Section 1833(t) of the Social Security Act (the Act), as added by section 4523 of the Balanced Budget Act of 1997 (BBA), Pub. L. 105-133, provided for implementation of a prospective payment system (PPS) for hospital outpatient services furnished to Medicare beneficiaries. The Medicare, Medicaid, and SCHIP Balanced Budget Refinement Act of 1999 (BBRA), Pub. L. 106-113, amended section 1833(t) of the Act to make major changes that affected the new prospective payment system. On April 7, 2000, we published a final rule with comment period in the Federal Register (65 FR 18434) to implement the new PPS for hospital outpatient services. The new system established payment rates for each service paid under this system using ambulatory payment classification (APC) groups. On June 30, 2000, we published a notice in the Federal Register (65 FR 40535) announcing a delay in the effective date of the hospital outpatient PPS (OPPS) from July 1, 2000 (as set forth in the April 7, 2000 final rule) until August 1, 2000. Therefore, OPPS became effective on August 1, 2000. The regulations implementing the payment system appear at 42 CFR part 419.
On August 3, 2000, we published an interim final rule with comment period (65 FR 47670) that modified criteria that we use to determine which medical devices are eligible for transitional pass-through payments. On November 13, 2000, we published an interim final rule with comment period in the Federal Register (65 FR 67798) that provided for the annual update to the amounts and factors for OPPS payment rates effective for services furnished on or after January 1, 2001. We also responded to public comments on those portions of the April 7, 2000 final rule that implemented related provisions of the BBRA and public comments on the August 3, 2000 rule.
On August 24, 2001, we published a proposed rule in the Federal Register (66 FR 44672) that set forth proposed changes to the OPPS to implement applicable statutory requirements, including relevant provisions of the Medicare, Medicaid, and SCHIP Benefits Improvement and Protection Act of 2000 (BIPA) (Pub. L. 106-554), enacted on December 21, 2000, as well as changes arising from our continuing experience with the system. That document described proposed changes to the amounts and factors used to determine the payment rates for services paid under the hospital OPPS for CY 2002. These amounts and factors include the updated conversion factor, APC classifications and relative weights, wage index values, copayment amounts, and the discussion of a possible pro rata reduction to be applied to the transitional pass-through payments for certain drugs, biologicals, and medical devices.
We received approximately 400 timely items of correspondence containing multiple comments on the August 24, 2001 proposed rule. In this final rule, we will respond to those comments addressing the Secretary's estimate of the total amount of pass-through payments for CY 2002 and the need for a uniform reduction to those payments in 2002 as well as the determination of the OPPS conversion factor for CY 2002.
In a subsequent final rule to be published by December 1, 2001, we will address the remainder of the comments and include the tables necessary to calculate CY 2002 payment rates and beneficiary copayment amounts.
II. Transitional Pass-Through Payments
Section 1833(t)(6) of the Act provides for temporary additional payments or “transitional pass-through payments” for certain innovative medical devices, drugs, and biologicals. As originally enacted by the BBRA, this provision required the Secretary to make additional payments to hospitals for current orphan drugs, as designated under section 526 of the Federal Food, Drug and Cosmetic Act; current drugs, biologicals, and brachytherapy devices used for the treatment of cancer; and current radiopharmaceutical drugs and biologicals. Transitional pass-through payments are also required for new medical devices, drugs, and biologicals that were not being paid for as a hospital outpatient service as of December 31, 1996 and whose cost is “not insignificant” in relation to the OPPS payment for the procedures or services associated with the new device, drug, or biological. Under the statute, transitional pass-through payments for any given device, drug, or biological are to be made for at least 2 years but not more than 3 years.
Section 1833(t)(6)(D)(i) of the Act sets the payment rate for drugs and biologicals eligible for a transitional pass-through payment as the amount by which the amount determined under section 1842(o) of the Act (that is, 95 percent of the applicable average wholesale price) exceeds the portion of the otherwise applicable fee schedule amount (that is, the APC payment rate) that the Secretary determines is associated with the drug or biological. Section 1833(t)(6)(D)(ii) of the Act sets the transitional pass-through payment for a medical device at the amount by which the hospital's charges, adjusted to cost, exceeds the portion of the otherwise applicable fee schedule amount (that is, the APC payment rate) that the Secretary determines is associated with the device.
B. Pro Rata Reductions
Section 1833(t)(6)(E) of the Act limits the total projected amount of transitional pass-through payments for a given year to an “applicable percentage” of projected total payments under the hospital OPPS. For a year before 2004, the applicable percentage is 2.5 percent; for 2004 and subsequent years, the applicable percentage is a percentage specified by the Secretary up to 2.0 percent. If the Secretary estimates before the beginning of the calendar year that the total amount of pass-through payments in that year would exceed the applicable percentage, section 1833(t)(6)(E)(iii) of the Act requires a uniform prospective reduction in the amount of each of the transitional pass-through payments for that year to ensure that the limit is not exceeded.
In the August 24, 2001 proposed rule setting out the proposed changes for CY 2002 in the OPPS, we described the extensive data base that we have constructed in order to prepare for making an estimate of pass-through payments for 2002. This data base includes outpatient claims data submitted by hospitals for services furnished on or after July 1, 1999 and before July 1, 2000, as well as device cost and utilization data extracted from applications for pass-through status submitted by manufacturers, hospitals, specialty societies, and other entities. In their applications for pass-through status, manufacturers have supplied information on the expected cost to hospitals of devices and the procedures with which the devices are commonly used.
In the August 24, 2001 proposed rule, we indicated that the information collected to that time suggested that a significant pro rata reduction might be required for 2002 in order to meet the statutory limit on the amount of the pass-through payments. We also announced that we were considering the appropriateness of a number of possible alternative approaches that would have the effect of minimizing the amount of any potential reduction in these Start Printed Page 55859payments. Finally, we presented a discussion of the methodology that we contemplate using in the development of our estimate.
We announced in the August 24, 2001 proposed rule that we were considering a number of possible approaches to different technical aspects of estimating payments. We also indicated that, as is always the case in making these types of estimates, it would be necessary to make a number of assumptions in interpreting the data. We were tentatively contemplating using the following assumptions and techniques in developing our methodology:
1. Data and Procedures for Estimation
We planned to base the estimate of 2002 pass-through expenditures on the claims we would use to set payment rates for 2002; 2001 pass-through amounts for drugs and radiopharmaceuticals; and device cost and use data from pass-through applications submitted by manufacturers, hospitals, specialty societies, and other entities. We proposed to make projections to CY 2002 on the basis of price, volume, and service-mix inflators consistent with our baseline for OPPS spending. Estimates for drugs, radiopharmaceuticals, and devices would be made separately and combined for the final projection of pass-through spending.
2. Drug Estimate
We also proposed to identify those drugs eligible for pass-through status that have been separately billed to the Medicare program on the claims that we intend to employ for the estimate. We proposed to multiply the frequency of use for each of these drugs (that is, the number of line items multiplied by the number of units billed as shown in the claims data) by its 2001 pass-through payment amount. We would determine a reasonable adjustment to account for those drugs that do not appear in the claims data. Such an adjustment might take into account the extent to which the noncoded items were classified as orphan drugs and therefore to be used infrequently.
3. Radiopharmaceutical Estimate
As in the case of the drug estimates, we proposed to identify those radiopharmaceuticals eligible for pass-through status that were separately billed to Medicare in the claims data file. We proposed to estimate expenditures for these radiopharmaceuticals directly as described above. For radiopharmaceutical drugs, we would multiply the frequency of use for each item by the 2001 pass-through amount. We would estimate expenditures for the remaining items by using the frequency counts for all nuclear medicine procedures not billed with one of these radiopharmaceuticals.
4. Device Estimate
We proposed to estimate the transitional pass-through payments attributable to devices by linking the frequencies for all device-related procedures in the claims data file with the cost and use data supplied by the manufacturers or other entities as part of their applications for pass-through status. We proposed to match each device eligible as of January 2001 with the procedures with which it would be used. We would then calculate an average cost for each device or device package associated with a procedure.
The statute requires that we calculate transitional pass-through payments for devices by adjusting the hospital's charge for the device to cost and then subtracting an amount that reflects the device costs already included in the payment for the associated APC. As we explained in the April 7, 2000 final rule (65 FR 18481), we were not able to implement these subtractions at the time of implementation of the system. For 2001, we made these deductions for pacemakers and neurostimulators. In the August 24, 2001 proposed rule, we proposed to make these subtractions for most other devices beginning in 2002. For the purpose of doing this estimation, we proposed to deduct these amounts from each device package before multiplying that cost by the procedure frequencies.
5. Projecting to 2002
We planned to project prices and quantities in the estimates determined as above to 2002 using actuarial projections of price and enrollee volume and service increase consistent with the OPPS baseline. We then proposed to add the three separate results in an estimate of total pass-through spending.
We received over 80 comments in response to our proposal, including comments from national provider associations, hospitals, device and drug manufacturers, and their representative associations.
Comment: Many commenters expressed concern about the data and the methodology that we proposed to use in developing an estimate of pass-through spending for 2002. A number of these commenters specifically cited the lack of actual claims data under the OPPS as one major concern. Commenters doubted that claims from the period before implementation of the OPPS would contain sufficiently accurate coding or adequately reflect utilization of pass-through items to allow us to make an accurate estimate.
Response: We believe that the outpatient claims data submitted by hospitals for services furnished on or after July 1, 1999 and before July 1, 2000 provide adequate information for use in projecting pass-through spending for 2002. These claims are the most recent outpatient data available to us, and we are also using these claims for the purpose of recalibrating the APC relative weights for 2002. These data provide useful information on the frequencies of the procedures in which pass-through items are used, as well as of the utilization frequencies of some of the pass-through items themselves (especially drugs). Claims data for the period after the implementation of the prospective payment system are not at present available for analysis. Under the best of circumstances, we would only expect data from the prior calendar year to be available. Thus, only data from the first 5 months under the OPPS (August to December 2000) might be available at this point in the update cycle. However, the extent to which these data, were they available, would offer any significant improvement for these purposes is unclear. Those claims data would not contain information on most of the devices approved for pass-through payment in 2002 because those items became eligible for payment after January 1, 2001. It would still be necessary to use a crosswalk that maps devices to procedures in order to project spending for pass-through devices in 2002.
Comment: Some commenters questioned the appropriateness of using data on cost, utilization, and coding derived from applications from device manufacturers for pass-through status in developing the estimate. These commenters specifically contended that these data were not collected for the purpose of establishing payment amounts. They also contended that the cost, utilization, and coding information were not requested in a specific format on the applications, and that this information was therefore not presented in an appropriately consistent manner for the requisite level of analysis.
Response: The assertions of the commenters are incorrect. We were aware that we would have to develop estimates of pass-through costs for the purposes of applying the statutory limit on these costs when we developed the applications for pass-through status. We also knew at that time that we needed cost data in order to apply the cost significance eligibility criteria for pass-Start Printed Page 55860through status. We deliberately developed the applications in order to generate reliable information on the cost, coding, and use of devices.
We specifically requested that the following information be uniformly provided: “Current cost of the item or service to hospitals (i.e., actual cost paid by hospitals net of all discounts, rebates, and incentives in cash or in-kind).” We also specifically asked applicants to identify the Healthcare Common Procedure Coding System (HCPCS) or American Medical Association Current Procedural Terminology (CPT) service codes associated with each device application. We certainly assume that the manufacturers would be reliable sources of this information. We did not derive information on utilization frequencies solely from the manufacturers' applications for pass-through status. Rather, we calculated our projections of utilization by analyzing the claims at our disposal using a crosswalk of pass-through items to procedure codes that our clinical staff developed from the information supplied by manufacturers. The crosswalk established the CPT codes and the APCs with which the particular devices are used, while the claims data provided the frequency of use for devices in those APCs.
Comment: Many commenters questioned the validity of matching items eligible for pass-through payment with the procedures with which they would be used, citing the complexity of the CPT coding system and the variety and number of pass-through items that could be associated with particular procedure codes. The commenters asserted that a crosswalk that matched pass-through items and codes would require external review and validation. One commenter expressed concern that this crosswalk could overstate the frequencies of device use, since devices may not actually be used in every procedure where they could have been used.
Response: Using the information from the applications, our clinical staff (including physicians, nurses, and coding specialists) developed the device-to-procedure crosswalk. The staff employed a rigorous process of analysis and verification in developing this crosswalk. All members of the staff reviewed each tentative assignment of pass-through items to procedures. In order to minimize the use of individual clinical judgement, the staff made final decisions only after reaching a consensus on the assignment of pass-through items to each procedure. We are confident that the crosswalk reflects an appropriate level of analytical rigor and independent validation.
The clinical staff also followed a conservative approach in matching devices to procedures. Specifically, they assigned pass-through items only to procedures for those pass-through items that would be typically used, even if there were other procedures in which those items might occasionally be used. Moreover, the crosswalk specifically accounts for procedures where a device or devices might be used less than 100 percent of the time. We are confident that the crosswalk procedure itself has not in any way led to an overstatement of pass-through costs.
Comment: Many commenters asserted that the method described in the August 24, 2001 proposed rule is necessarily flawed because we excluded multiple service claims from the data.
Response: We use only single service claims in calibrating the APC weights because we have no way of allocating ancillary service costs among the various procedures on multiple service claims. However, for all other facets of our annual calculation of OPPS payment amounts and factors (for example, our estimate of outlier spending and resulting thresholds), we use both single and multiple service claims. Similarly, we included both single service and multiple service claims in developing our estimate of pass-through costs and the pro rata reduction. Specifically, we used both types of claims in developing the count of the procedures associated with the use of pass-through items.
Comment: Several commenters questioned whether we had provided sufficient notice of a possible pro rata reduction to comply with the requirements of the Administrative Procedure Act. These commenters contended that the description of the proposed method for calculating a pro rata reduction was too general to allow for adequate public comment and that the data supporting the need for such a reduction should have been published to allow for public review and analysis. One commenter argued that a pro rata reduction cannot be implemented legally without specifying the size of the reduction in a proposed rule with an adequate comment period. A commenter from the drug industry stated that data on utilization should be released in time for review and analysis so that the industry could have sufficient opportunity to assess the contribution of its products to pass-through spending and to develop options and recommendations for legislative and administrative action.
Response: At the time the August 24, 2001 proposed rule was published, we had assembled a data base and developed a preliminary methodology for making an estimate of pass-through spending in 2002. Our best judgment was that further review and analysis of the data and methodology were warranted before we announced a specific estimate of 2002 pass-through spending and any requisite pro rata reduction. We therefore confined our discussion in the proposed rule to the information that was then clearly known to us, namely the general methodology that we proposed to employ, and the likely magnitude of a pro rata reduction.
We believe that our description of our data sources and methodology allowed ample opportunity for substantive comment, and we did receive numerous substantive comments on both the data sources and the methodology. Furthermore, our notice that a “significant pro rata reduction could be required for 2002” provided interested parties sufficient opportunity to assess the situation and to develop options and recommendations for both legislative and administrative action. We received many comments with proposals and recommendations for administrative action, as well as proposals for possible legislative measures that commenters have urged us to bring to the attention of the Congress. (We respond to these comments below.) Finally, we note that section 1833(t)(12) of the Act provides that there “shall be no administrative or judicial review * * * of the application of any pro rata reduction * * *.”
Based on the methodology described above, we estimate that the total amount of transitional pass-through payments for 2002 would exceed the limit of 2.5 percent of total spending under the OPPS. Specifically, we estimate that total transitional pass-through payments for 2002 would be about $2.26 billion, of which about $1.89 billion is attributable to devices and about $0.37 billion is attributable to drugs and radiopharmaceuticals. (Of the latter number, radiopharmaceuticals account for about $0.17 billion, and drugs account for about $0.20 billion.) Estimated total pass-through payments would thus be approximately 13 percent of the baseline projection of $17.5 billion in total payments (including both program and beneficiary payments) to hospitals in 2002 under the OPPS, and pass-through payments for devices are approximately 11 percent total of OPPS payments in 2002. Based on this estimate, a pro rata reduction of 80.7 percent would be required by the statute. Start Printed Page 55861
Many commenters recommended measures to delay or mitigate the effects of any pro rata reduction. These comments and our responses are set forth below.
Comment: A number of commenters requested a 1-year delay in implementing a pro rata reduction, citing their concerns about data limitations and methodological weaknesses as reasons for such a delay. Other commenters recommended that any pro rata reduction should be phased in over a period of several years in order to allow vendors and hospitals adequate time to adjust to the reduced payment.
Response: The statute specifically requires that, if the Secretary estimates before the beginning of a year that the amount of the pass-through payments for that year will exceed the limit, “the Secretary shall reduce pro rata the amount of each of the additional payments * * * for that year.” (Emphasis added.) Therefore, we can legally neither delay the reduction until a later year nor spread the reduction over the payments for several years. We now have an estimate of pass-through spending for 2002, and we have explained above why we believe that our methodology for determining it was reasonable.
Comment: Several commenters recommended that we use the amount “reserved” for outlier payments (up to 2.5 percent of OPPS payments) to increase the amount of money available for pass-through payments in order to reduce the need for a pro rata reduction. (As we have explained in other contexts, outlier payments are financed through a prospective reduction to PPS rates. We do not “set aside” money in a discrete fund to pay for outliers, and the same is true for pass-through payments.) Another commenter advocated that we fold the pass-through payments into the outlier “pool,” and pay for the high costs of new technology as part of our payment for high cost services of all types. Other commenters contended that the 2.5 percent limit on pass-through payments was inadequate to pay for the costs of new technologies and recommended that the limit be raised.
Response: The statute provides for both the outlier and transitional pass-through payments and establishes the 2.5 percent limits on those payments for the years before 2004 (when the limit for outliers increases to 3.0 percent and the limit for transitional pass-throughs decreases to 2.0 percent). Thus, we do not have the administrative authority to make any of the changes that these commenters have recommended. Rather, legislative action would be required to make any of these changes.
Comment: One commenter recommended that we move the procedures associated with pass-through items to the inpatient list so that they can be paid under the hospital inpatient PPS.
Response: We believe that the commenter is confused about the purpose of the inpatient list. The inpatient list identifies procedures that may not be paid under the OPPS. If medically necessary, any procedure, including those not on the inpatient list, that is performed in an inpatient setting may be paid under the hospital inpatient PPS. We decide which procedures are included on the inpatient list on the basis of clinical criteria alone. We believe that procedures should not be included on the inpatient list for payment reasons.
Comment: Several commenters asserted that a pro rata reduction will be necessary in 2002 only because we have failed to implement the transitional pass-through program as the Congress intended it. Specifically, these commenters contended that we have failed to restrict the pass-through payments to the incremental costs of new technologies by identifying the costs for predecessor technologies that are already represented in the APC payment rates and subtracting those amounts from the pass-through payments, as contemplated by the statute.
Response: Because of constraints on our data analysis before implementation of the pass-through provision, we did have difficulty initially in determining appropriate offsets for the technology costs already represented in the payment rates for many APCs. However, in the August 24, 2001 proposed rule, based on the updated claims data, we proposed appropriate offset amounts for 25 APCs that are associated with the use of pass-through devices. We will announce our final computations of the offset amounts for the affected APCs in a subsequent rule, which will be published before the beginning of the year. We will thus have substantially accounted for the technology costs that are already represented in APC payment rates, and, therefore, the magnitude of the pro rata reduction cannot be attributed to a failure to restrict pass-through payments to the incremental costs of new technology.
Comment: Many commenters expressed their concern about the prospect for a significant pro rata reduction, and the potential effect of such a reduction on access of Medicare beneficiaries to necessary treatments in the outpatient setting. These commenters therefore urged us not to implement a pro rata reduction in 2002.
Response: A significant pro rata reduction could affect the availability of improved medical technology for Medicare beneficiaries, but the possibility of such a result is inherent in the statutory scheme. The Congress has set up a scheme to limit the aggregate amount of (projected) pass-through payments in a given year, including a requirement for a pro rata reduction. The statute reflects a balance of competing considerations— providing pass-through payments for new technologies but limiting the aggregate amount of those payments so that payments for other services are not reduced significantly (if there were no limit on projected pass-through payments, then, other things being equal, we would be reducing the base payments by 13 percent rather than 2.5 percent to ensure budget neutrality). In order to promote access to new technologies, we have decided to take a significant administrative action in order to reduce the size of the reduction. That action, which incorporates a portion of the pass-through costs into the base APCs, is discussed below. We believe that there are no other feasible and prudent administrative options available to reduce the amount of a pro rata reduction.
Comment: Several commenters, including device manufacturers and the associations that represent them, recommended that we fold the costs of pass-through devices into the base APC rates. These commenters noted that such a step would limit pass-through payments to the incremental costs of new technologies, and at least reduce the size of a pro rata reduction. Some of these commenters urged us not to implement any pro rata reduction until we have revised the base rates to include these costs.
Response: The transitional pass-through payment provision was intended as an interim measure to allow for adequate payment of new, innovative technology while we collected the necessary data to incorporate the costs for these items into the base APC rates. The statute and regulations specifically limit the payment for individual pass-through items to at least 2 years but no more than 3 years, with the intention that the costs for these items should be incorporated into the APC rates for the procedures associated with these items after that period. We agree with these commenters that we have the discretion to fold some of these costs into the APC rates before the time period for Start Printed Page 55862transitional payment of specific devices has expired. (We cannot fold all of the current pass-through costs into the APC rates at this time, because the statute implies that pass-through payments for devices that have been eligible for less than 2 years must continue to be made.)
We also agree with the commenters that it is reasonable and prudent to incorporate some of the pass-through costs into the APC rates now, before we are legally required to do so, in order to mitigate the effects of the significant pro rata reduction that is mandated by the statute. Prudence also dictates, however, that we take into account all the other effects of incorporating these costs into the base rates at this time in deciding how much of the costs to incorporate into the base rates for 2002.
In addition to reducing the size of the pro rata reduction, incorporating a portion of the cost of pass-through devices into the basic APC costs has an effect on the APC relative weights. This is because the costs to be incorporated are not evenly distributed among the APCs, but are rather concentrated in a relatively small number of APCs that include the procedures that use pass-through devices. The effect of incorporating pass-through costs into the APCs is thus to decrease the APC weights for services such as clinic visits, preventive care, and diagnostic tests, while the weights for the APCs into which the pass-through costs are incorporated generally increase, often by large percentages.
In addition, increases in the relative weights for some APCs can lead to increases in beneficiary copayments because, by statute, the coinsurance rate cannot be less than 20 percent of the payment rate for an APC. We note, however, that beneficiaries are protected from much of this increase on an individual APC basis because section 1833(t)(8)(C) of the Act limits the copayment for a procedure performed in a year to no more than the amount of the inpatient hospital deductible for that year. For CY 2002, that amount is $812.
Accordingly, choosing a percentage of the estimated pass-through costs for devices to fold into the APCs associated with the use of those devices requires us to balance several considerations. We must be mindful not only of the effect on transitional pass-through payments for drugs and devices, but also on the payments for other services and on beneficiary copayments. In addition, we note that, in CY 2003, almost all of the items currently receiving transitional pass-through payments will have reached the end of their eligibility for this payment status, and their costs must be folded into the APCs at that time. Changes made in CY 2002 will thus provide a transition to rates in CY 2003. After weighing these factors, and considering the potential impacts of a variety of options, we have concluded it is appropriate to incorporate 75 percent of the estimated pass-through costs for devices into the procedure APCs associated with these devices. We are incorporating 75 percent of the device pass-through payments, or approximately $1.4 billion, into the costs that are used to establish the APC relative weights for 2002.
We are not incorporating any of the current drug and biological pass-through costs into the APCs for two reasons. First, the costs for drugs and biologicals are already incorporated to a large extent into a base APC rate. As discussed more fully in the August 24, 2001 proposed rule (66 FR 44701), we assume that, for most drugs, 68 percent of the AWP is acquisition costs of the drug or biological that is already recognized in the base costs. Thus, the pass-through payment for those drugs and biologicals is 27 percent of the AWP. Second, it is generally not feasible to determine which APCs are associated with the use of drugs and biologicals from our current claims data. Unlike devices, which are used solely in the performance of certain procedures, drugs and biologicals can be provided in connection with almost any outpatient service. Thus, we are postponing the incorporation of these costs until we have data that allow us to determine the APCs with which the use of these items is associated. We note, however, that the pro rata reduction will be applied to the pass-through payment for drugs and biologicals as well as devices.
To incorporate 75 percent of the device payments, we are employing the following methodology. We use the crosswalk that we developed as part of the methodology for estimating total pass-through spending as the basis for determining the device costs that we include in setting the relative weight for each APC. As we have discussed above, this crosswalk matches devices to the typical procedures in which they are used.
In developing the total pass-through estimate, we used this crosswalk to produce a device package for each CPT code associated with device use, based on the device or devices used in each procedure included in an APC. We adjusted the costs of each package by subtracting the device costs already represented in the payment amount for the APC. (These are the costs that we deduct from each pass-through payment to ensure that the pass-through payments are limited to the incremental costs of the new technologies. The principle for making this subtraction is the same in each case: to avoid double-counting costs already represented in the APC rates.) We then add 75 percent of these adjusted costs of the package to the costs at the claim level for each device-related procedure in the APC. At this point, we determine a revised median cost for the APC. That new median cost in turn is the basis for the APC's new relative weight.
The costs folded in will affect the relative weights of the APCs. The resulting APC payment rates will not increase on a dollar-for-dollar basis with the device costs folded into the APCs. In most cases, the device costs folded into an APC will not be uniformly distributed among the procedures in that APC. This is because procedures in an APC may require different types or numbers of devices and some procedures may not require devices at all. Therefore, the increase in median cost for an affected APC is unlikely to exactly equal the amount of the cost folded in. Furthermore, the statute requires that APC recalibration and reclassification changes be made in a manner that assures that aggregate payments will be neither greater nor less than they would have been without the changes. Changes in an APC's payment rate therefore cannot be expected to vary on a dollar-for-dollar basis with changes in the costs used to determine the APC's relative weight.
Finally, we note that the initial payments under the OPPS were calculated to be budget neutral to the methodology in use before the implementation of the OPPS. The prior payment methodology paid hospitals, on average, approximately 83 percent (the actual payment-to-cost ratio under the prior system) of their costs for furnishing outpatient services. Under the pass-through payment methodology, eligible devices are paid at 100 percent of their costs. Once these costs are incorporated into the APCs, they will also be paid at rates calculated to reflect these reductions.
The increase in APC rates due to the incorporation of these pass-through costs will be offset against the estimated 2002 pass-through payments. (As discussed above, we subtract the amount of the pass-through costs represented in the rate for the associated APC from each pass-through payment.) The remaining amount of estimated pass-through spending for 2002, once we have applied these offsets, will be subject to the pro rata reduction. Because we have not completed the recalculation of the adjusted APC payments, we are unable to provide the Start Printed Page 55863specific amount of the pro rata reduction at this time. We will announce the exact amount of the reduction that will be required before the beginning of 2002. In the meantime, we are announcing that we expect the required reduction will be in the range of 65 to 70 percent. As can be seen from this estimate, folding in 75 percent of the device costs into the APCs does not reduce the pro rata by 75 percent. The following is a simplified illustration of the process.
Assume there is only one device eligible for a pass-through and only one associated APC. That APC has a payment rate of $3,000, of which $1,000 is associated with device costs already in the APC. If a hospital bills a device with that APC whose charge adjusted to cost is $9,000, the payment for the pass-through is $9,000 minus $1,000, or $8,000. Thus, the payment for the entire service is $3,000 for the base APC and $8,000 for the device, for a total payment of $11,000. The pro rata reduction would be applied to the $8,000. If we were to implement the 80.7 percent reduction, the total payment would be $4,544 ($3,000 + $8,000 (0.193)).
For the 75 percent fold-in, we would first adjust the $9,000 device cost to account for the $1,000 in device costs already represented in the APC rate. The remaining $8,000 represents the adjusted costs for the device. We would then incorporate $6,000 of the $8,000 in adjusted costs into the APC rate. As discussed above, the increase in the APC rate is not a dollar-for-dollar match with the amount folded in. Therefore, assume that the APC rate increases by $3,500, for a total of $6,500. The $6,500 payment rate now reflects $4,500 in device costs “ the original $1,000 plus the difference between the original APC payment ($3,000) and the APC payment rate after the fold-in ($6,500), or $3,500. The increase in the amount of device costs reflected in the APC is a dollar-for-dollar match with the increase in the payment rate. The total payment for the service is now $6,500 for the base APC and $4,500 for the device ($9,000 minus $4,500), for a total payment of $11,000. Even though 75 percent of the $8,000, or $6,000, has been folded into the APC rate, the pass-through payment (before any pro rata reduction) is reduced by only $4,500, to $4,500. Thus, folding in 75 percent of the device costs does not reduce the total pass-through estimate by that same 75 percent. However, any remaining pro rata reduction would be applied only to the $4,500. Based on an expected reduction of between 65 and 70 percent, total payment would be between $8,075 and $7,850, respectively.
Comment: Several commenters requested that we clarify how the incorporation of pass-through costs into the associated APCs would affect the APC payments. Specifically, some of these commenters requested that we clarify whether there would be a dollar-for-dollar match between the costs incorporated into an APC and the resulting increase in the APC's rate. Others asked whether there would be a dollar-for-dollar match between the increase in the APC's rate and the increase in the reduction in the pass-through payments to account for the device costs incorporated into the APC.
Response: As discussed in the response immediately preceding, there is not a dollar-for-dollar match between the costs incorporated into an APC and the resulting increase in the APC's payment rate. There is, however, a dollar-for-dollar match between the increase in an APC's rate and the increase in the reduction for the pass-through payment for devices associated with that APC. This is because the additional payment for a pass-through item equals the amount by which the hospital's cost for the item exceeds the portion of the applicable APC payment amount that is associated with the item. There is thus necessarily a dollar-for-dollar match between the increase in the APC's rate that is due to the new costs being incorporated into the APC, and the reduction applied to the pass-through payments.
Comment: Several commenters made specific requests for data files and other information related to any possible pro rata reduction. These requests included the following:
- The data files used to estimate pass-through spending, including claims data from the period July 1, 1999 and July 1, 2000.
- A comprehensive description of the methods used to identify gaps in the reporting of drugs, biologicals, and devices, and the assumptions used to estimate utilization of pass-through items.
- An estimate of projected pass-through payments for 2002, including breakdowns by category (orphan drugs, cancer drugs, devices, etc.).
- An estimate of the magnitude of any proposed reduction in pass-through payments to meet the 2.5 percent statutory cap.
- A detailed description of how any pro rata reduction would be implemented.
Response: It is our general practice to release the data we use in setting Medicare payment amounts to the public when we announce proposed payment amounts. Some of the data requested by these commenters, especially the relevant claims data for the period July 1, 1999 and July 1, 2000, were in fact released at the time of the August 24, 2001 proposed rule because these data were used in developing the proposed APC payment rates in that rule. We did publish a substantive description of the methodology that we were proposing to use in developing an estimate of pass-through costs, and we received numerous comments on that proposed methodology. To the degree that we did not release some of the other information requested by these commenters, such as an estimate of a proposed pro rata reduction and a breakdown of pass-through costs by category, it was because we were still reviewing our methodology and analyzing the data. We did, however, present the public with the likely magnitude of a reduction at that time.
In this final rule, in response to the comments, we are providing more information on the methodology that we have used to determine the pro rata reduction. We are also providing a detailed account of our calculation of 2002 pass-through costs. We plan to release additional information when we announce the exact percentage of the required pro rata reduction before the beginning of the year. The pro rata reduction will be implemented by our systems as a uniform reduction to every pass-through payment.
Comment: The Medicare Payment Assessment Commission commented that the transitional pass-through provision has three flaws:
- The use of categories to determine the eligibility of devices allows devices the costs of which had already been taken into account in setting the base rates to qualify for pass-through payments.
- The pass-through payments for drugs and biologicals are set at 95 percent of average wholesale cost, thus creating an incentive to increase Medicare payments by raising prices for these items.
- Pass-through payment rates are based on hospital-specific cost-to-charge ratios, allowing hospitals to increase their payments by raising the charges for eligible items.
The Commission recommended that the Congress enact three statutory changes to improve the transitional pass-through provision:
- Restrict the eligibility for pass-through payments to technologies that are new or substantially improved and that add substantially to the cost of care.
- Allow for the costs of pass-through items to be completely incorporated into the base APC rates more quickly than the current statutory eligibility period of 2 to 3 years allows. Start Printed Page 55864
- Replace the facility-specific payments for devices with national payments.
Response: We appreciate the Commission's comments about flaws in the transitional pass-through provision. We will be available to provide technical assistance to the appropriate congressional committees in developing measures to improve the provision. We do note, however, that although the use of categories allows devices whose costs had previously been included in the calculation of the APC payment rates to qualify for pass-through payments, those payments will be reduced by the amount that we have calculated to be reflected in that APC. However, this subtraction of the costs in the APC may not reduce the pass-through payment for those devices to zero.
III. Conversion Factor Update for CY 2002
Section 1833(t)(3)(C)(ii) of the Act requires us to update the conversion factor used to determine payment rates under the OPPS on an annual basis. Section 1833(t)(3)(C)(iv) of the Act, as redesignated by section 401 of the BIPA, provides that for 2002, the update is equal to the hospital inpatient market basket percentage increase applicable to hospital discharges under section 1886(b)(3)(B)(iii) of the Act, reduced by one percentage point. Further, section 401 of the BIPA increased the conversion factor for 2001 to reflect an update equal to the full market basket percentage increase amount.
To set the proposed OPPS conversion factor for 2002, we increased the 2001 conversion factor of $50.080, which reflects the BIPA provision of the full market basket update, by 2.3 percent, that is, the full market basket percentage increase of 3.3 percent minus 1 percentage point.
In accordance with section 1833(t)(9)(B) of the Act, we further adjusted the conversion factor for 2002 to ensure that the revisions we made to update the wage index are made on a budget-neutral basis. A proposed budget neutrality factor of 0.9924 was calculated for wage index changes by comparing total payments from our simulation model using the proposed FY 2002 hospital inpatient PPS wage index values to those payments using the current (FY 2001) wage index values.
The increase factor of 2.3 percent for 2002 and the required wage index budget neutrality adjustment of 0.9924 resulted in a proposed conversion factor for 2002 of $50.842.
Based on the 2.3 percent update factor and the final FY 2002 hospital inpatient wage index values, the final wage index budget neutrality adjustment is 0.9936, which results in a final conversion factor for 2002 of $50.904.
We received one comment on the calculation of the conversion factor.
Comment: One commenter requested clarification of the methodology used to calculate the conversion factor for CY 2002, particularly as it relates to the payment update provided by section 401 of BIPA. The commenter is concerned that we did not explain that the CY 2001 conversion factor we set forth in the August 24, 2001 proposed rule as the basis for the CY 2002 conversion factor was never used to make payment in CY 2001.
Response: Before the enactment of BIPA on December 21, 2000, section 1833(t)(3)(C)(iii) of the Act provided for a 2001 update of the market basket percentage increase reduced by 1 percentage point. This is the update that was implemented by the November 13, 2000 final rule (65 FR 67827).
Section 401(a) of BIPA amended section 1833(t)(3)(C)(iii) (redesignated by section 401(b) of BIPA as section 1833(t)(3)(C)(iv)) of the Act to provide for a full market basket percentage increase for CY 2001. However, section 401(c) of BIPA also provided a special payment rule for CY 2001 that requires the payment rate for services furnished under the OPPS on or after April 1, 2001 and before January 1, 2002 to be updated by an additional 0.32 percent to account for the timing of the implementation of the full market basket update for 2001. Thus, the conversion factor used to make payment on or after January 1 and before April 1, 2001 was based on a market basket percentage increase minus 1 percentage point, and the conversion factor used to make payment on or after April 1, 2001 was based on a full market basket percentage increase increased by 0.32 percent. Payment was never made in 2001 using a conversion factor based on a full market basket percentage increase. However, it is this last conversion factor (which is equal to $50.080) that must be used to update the conversion factor for CY 2002.
IV. Collection of Information Requirements
This document does not impose information collection and recordkeeping requirements. Consequently, it need not be reviewed by the Office of Management and Budget under the authority of the Paperwork Reduction Act of 1995 (44 U.S.C. 35).
V. Regulatory Impact Analysis
We have examined the impacts of this final rule as required by Executive Order 12866 (September 1993, Regulatory Planning and Review) and the Regulatory Flexibility Act (RFA) (September 19, 1980 Public Law 96-354). Executive Order 12866 directs agencies to assess all costs and benefits of available regulatory alternatives and, if regulation is necessary, to select regulatory approaches that maximize net benefits (including potential economic, environmental, public health and safety effects, distributive impacts, and equity). A regulatory impact analysis (RIA) must be prepared for major rules with economically significant effects ($100 million or more annually).
The statutory effects of the provisions that are implemented by this final rule result in expenditures exceeding $100 million per year. We estimate the total impact of these changes for CY 2002 payments compared to CY 2001 payments to be approximately a $400 million increase. Therefore, this final rule is an economically significant rule under Executive Order 12866, and a major rule under 5 U.S.C. 804(2).
The RFA requires agencies to determine whether a rule will have a significant economic impact on a substantial number of small entities. For purposes of the RFA, small entities include small businesses, nonprofit organizations, and government agencies. Most hospitals and most other providers and suppliers are small entities, either by nonprofit status or by having revenues of $5 to $25 million or less annually (see 65 FR 69432). For purposes of the RFA, all providers of hospital outpatient services are considered small entities. Individuals and States are not included in the definition of a small entity.
In addition, section 1102(b) of the Act requires us to prepare a regulatory impact analysis if a rule may have a significant impact on the operations of a substantial number of small rural hospitals. This analysis must conform to the provisions of section 604 of the RFA. With the exception of hospitals located in certain New England counties, for purposes of section 1102(b) of the Act, we define a small rural hospital as a hospital that is located outside of a Metropolitan Statistical Area (MSA) and has fewer than 100 beds, or New England County Metropolitan Area (NECMA). Section 601(g) of the Social Security Amendments of 1983 (Pub. L. 98-21) designated hospitals in certain New Start Printed Page 55865England counties as belonging to the adjacent NECMA. Thus, for purposes of the OPPS, we classify these hospitals as urban hospitals.
It is clear that the changes in this final rule affect both a substantial number of rural hospitals as well as other classes of hospitals, and the effects on some may be significant. The discussion below, in combination with the rest of this final rule, constitutes a regulatory impact analysis.
Section 202 of the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4) also requires that agencies assess anticipated costs and benefits before issuing any rule that may result in an expenditure in any one year by State, local, or tribal governments, in the aggregate, or by the private sector, of $110 million. This final rule does not mandate any requirements for State, local, or tribal governments.
Executive Order 13132 establishes certain requirements that an agency must meet when it publishes a proposed rule (and subsequent final rule) that imposes substantial direct costs on State and local governments, preempts State law, or otherwise has Federalism implications. We have examined this final rule in accordance with Executive Order 13132, Federalism, and have determined that it will not have any negative impact on the rights, roles, and responsibilities of State, local, or tribal governments.
B. Changes in This Final Rule
This final rule implements changes to the OPPS that are required by the statute. We are required under section 1833(t)(3)(C)(ii) of the Act to update annually the conversion factor used to determine the APC payment rates. In addition, section 1833(t)(6)(E)(iii) of the Act requires a uniform reduction in the amount of each of the transitional pass-through payments made in a year if the Secretary estimates, before the beginning of that year, that the total pass-through payments will exceed an applicable percentage of total payments estimated to be made under OPPS in that year. For CY 2002, the applicable percentage is 2.5 percent.
The projected aggregate impact of updating the conversion factor is to increase total payments to hospitals by 2.3 percent. As described in the preamble, a budget neutrality adjustment is made to the conversion factor to assure that the revision in the wage index does not affect aggregate payments.
C. Estimated Impacts of This Final Rule
The 2.3 percent update in the conversion factor results, in the aggregate, in an increase in payments for hospitals under the OPPS of approximately $400 million.
As discussed above in section II of this preamble, we have estimated that the total amount of pass-through payments for CY 2002 would be $2.26 billion if we did not fold in costs of pass-through devices into the base APC rates. Of that amount, approximately $0.37 million represents payments for drugs and biologicals and $1.89 billion represents payments for medical devices. Total OPPS payments in CY 2002 are estimated to be $17.5 billion. Because the estimate of pass-through payments exceeds 2.5 percent of estimated total payments, which is approximately $437 million (2.5 percent of $17.5 billion), we must implement a uniform reduction of all pass-through payments. Absent any administrative action, the estimate of the reduction necessary to account for the full pass-through estimate would be 80.7 percent. That is, we would pay 19.3 percent of the otherwise applicable pass-through payment for drugs, biologicals, and devices.
As further discussed above in section II of this preamble, in order to mitigate the effects of this significant pro rata reduction, we are incorporating, into the base APC costs, 75 percent of the cost of the devices currently eligible for pass-through payment. In the proposed rule, we estimated for most APCs that involve devices, an amount that represents the cost of devices already included in the APC payments. Those amounts would be subtracted from any pass-through payments associated with those APCs (before the pro rata reduction). That policy reduced the total estimate of pass-through payments by approximately $450 million. Because we are now incorporating additional device costs into the base APC costs, those subtraction amounts will increase to reflect the additional amounts included in the device-related APC payments. Thus, the total amount of pass-through payments estimated to be made in CY 2002 will be reduced, which will, in turn, reduce the amount of the pro rata reduction necessary to meet the 2.5 percent limit. As noted above in this preamble, because we have not yet completed our analysis and computations related to the fold in, we cannot yet announce the exact size of the pro rata reduction. However, we estimate that the amount of the reduction will be between 65 and 70 percent. The incorporation of costs into the base APCs results in the pro rata reduction being applied only to the marginal costs of the pass-through devices not incorporated into the APCs.
We believe that the changes we have made in this final rule will lessen the impact on hospitals of the required pro rata reduction on pass-through payments.
We estimate that the implementation of the pro rata reduction on pass-through payments for devices will affect urban hospitals more than rural hospitals and, in urban areas, large urban and teaching hospitals will be affected more than other urban hospitals. This is due to the fact that the types of outpatient procedures that use the pass-through devices are more frequently performed in large urban hospitals, particularly teaching hospitals. We estimate that the effect of the reduction on pass-through payments for drugs and biologicals may be more uniform across types of hospitals. Use of these items is more widespread among hospitals, although hospitals that furnish chemotherapy may be affected to a greater degree than others.
In accordance with the provisions of Executive Order 12866, this final rule was reviewed by the Office of Management and Budget.Start List of Subjects
