{"abstract":"This final rule establishes the standard for a unique health identifier for health care providers for use in the health care system and announces the adoption of the National Provider Identifier (NPI) as that standard. It also establishes the implementation specifications for obtaining and using the standard unique health identifier for health care providers. The implementation specifications set the requirements that must be met by \"covered entities\": Health plans, health care clearinghouses, and those health care providers who transmit any health information in electronic form in connection with a transaction for which the Secretary has adopted a standard (known as \"covered health care providers\"). Covered entities must use the identifier in connection with standard transactions. The use of the NPI will improve the Medicare and Medicaid programs, and other Federal health programs and private health programs, and the effectiveness and efficiency of the health care industry in general, by simplifying the administration of the health care system and enabling the efficient electronic transmission of certain health information. This final rule implements some of the requirements of the Administrative Simplification subtitle F of the Health Insurance Portability and Accountability Act of 1996 (HIPAA).","action":"Final rule.","agencies":[{"raw_name":"DEPARTMENT OF HEALTH AND HUMAN SERVICES","name":"Health and Human Services Department","id":221,"url":"https://www.federalregister.gov/agencies/health-and-human-services-department","json_url":"https://www.federalregister.gov/api/v1/agencies/221","parent_id":null,"slug":"health-and-human-services-department"},{"raw_name":"Office of the Secretary"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2004/01/23/04-1149.html","cfr_references":[{"chapter":null,"citation_url":null,"part":162,"title":45}],"citation":"69 FR 3434","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"May 23, 2005, except for the amendment to Sec. 162.610, which is effective on January 23, 2004.
