The Centers for Medicare & Medicaid Services (CMS) finalized a rule this month that is meant to drive healthcare transactions away from fax machines and postal mail. Too many providers are still using these old-school workflows with surprising frequency for submitting claims documentation today, and CMS believes the Adoption of Standards for Health Care Claims Attachments Transactions and Electronic Signatures Final Rule represents a major step toward fully electronic workflows, according to a press release. The regulation introduces the first HIPAA-adopted standards for claims attachments, allowing providers to securely transmit supporting clinical information—such as medical records, imaging, lab results, and telemedicine documentation—through standardized digital channels. It also establishes requirements for electronic signatures to ensure authentication and compliance. While the initially proposed rule included standards for both claims and prior authorization attachments, the final rule addresses only claims attachments with more evaluation promised in the future for prior auth rules.
Did you get my fax? In the announcement, CMS Administrator Mehmet Oz. MD, quipped: “The 1980s called, and they want their fax machines back.” By driving digital claims adjudication, the rule aims to streamline revenue cycle management tasks across the entire industry. CMS estimates the changes could save about $781 million annually. HIPAA-covered entities required to comply with the final rule by May 26, 2028, and some urgent cares may need to consult with revenue cycle experts to create a compliant roadmap to advance from their current fax processes to the CMS-required fully digital processes.
