A new federal regulation set to take effect on October 1, 2025, aims to move medical offices away from using fax machines by updating health information technology (IT) requirements. The U.S. Department of Health and Human Services (HHS) has introduced the Health Data, Technology, and Interoperability (HTI-4) rule. This policy requires healthcare IT systems to give doctors real-time access to prior authorization details and prescription drug prices during patient visits.
The HTI-4 rule is part of a broader policy update spanning 2,000 pages. It is designed to allow both physicians and patients to check drug costs instantly, consider less expensive alternatives, submit prior authorization requests electronically, and track their progress. According to HHS estimates, these updates could save providers millions of hours over the next ten years, which could amount to $19 billion in value.
Mehmet Oz, MD, who leads the Centers for Medicare & Medicaid Services, said the new regulation means “less red tape, faster answers, and more time focused on care.” HHS officials described it as a breakthrough that would lower administrative work for doctors and improve patient care.
Despite these advancements in efficiency, legal experts caution that the new rule does not resolve all issues related to prior authorization processes. While some paperwork may be reduced, challenges with insurance approvals are expected to remain.
Physician groups have expressed support for the changes. American Medical Association President Bobby Mukkamala, MD, stated that the update is a “tangible burden-reduction win,” adding that it may signal “the demise of the fax era in medicine.”
Following the announcement of this rule change, compliance will be voluntary except where tied to certain federal health programs. The deadline for full implementation is January 1, 2028. Health insurers back efforts to modernize communications but have raised concerns about uncertain timelines and limited incentives for providers.
Legal specialists advise healthcare organizations to prepare for these changes by making sure their practices comply with HIPAA rules as well as state privacy laws.
As digital solutions become more common in healthcare settings across the country, traditional fax machines are likely nearing obsolescence.
