New HIPAA Rule: Standards for Health Care Claims Attachments Transactions and Electronic Signatures

5/1/2026
On March 24, 2026, the U.S. Department of Health and Human Services (DHHS) published a final rule in the Federal Register implementing certain administrative simplification requirements under HIPAA. In short summary, the final rule establishes for the first time HIPAA-adopted standards for health care claims attachments transactions—that is, submission of attachments to support claims (which historically have been sent by outdated methods such as fax or postal mail). The rule mandates the electronic exchange of clinical and administrative documentation to support the claims-related processes, replacing fax and other manual methods. The rule also adopts a standard for electronic signatures to be used in conjunction with health care claims attachments transactions. The final rule is effective May 26, 2026, and compliance is required by May 26, 2028.
