The Centers for Medicare and Medicaid Services (CMS) has released the final rule that implements requirements of the Administrative Simplification subtitle of the Health Insurance Portability and Accountability Act of 1996 (HIPAA), and the Patient Protection and Affordable Care Act (ACA), as amended by the Health Care and Education Reconciliation Act of 2010, enacted on March 30, 2010.

Specifically, this final rule adopts standards for health care claims attachments transactions, which will support health care claims transactions and a standard for electronic signatures to be used in conjunction with health care claims attachments transactions.

The final rule will slash wasteful spending and antiquated paperwork by swapping out faxing and mailing for streamlined electronic transactions. This action lets providers spend less time on administrative hassle and more time caring for patients and is projected to save the healthcare industry approximately $781 million on an annual basis.

The final rule will be published in tomorrow’s (March 24, 2026) Federal Register and will become effective on May 19, 2026. Covered entities must comply by May 19, 2028.
