Every few years, an article circulates declaring that fax in healthcare is finally dying. The EHR will replace it. Secure messaging will replace it. HL7 and FHIR will replace it. Direct Trust will replace it. And every few years, the fax machines keep running, the fax servers keep processing, and the volume of faxes transmitted across the healthcare system stays stubbornly high.
In 2026, fax remains the dominant channel for inter-organizational document transmission in healthcare. Understanding why that is true, and what it means for organizations that depend on it, is more useful than waiting for a transition that has been predicted and delayed for three decades.
The Interoperability Problem Fax Solves
Healthcare in the United States is not a unified system. It is a collection of organizations, each running its own technology infrastructure, built at different times, on different platforms, with different integration capabilities. A community hospital may be on Epic. The specialist group down the street may be on athenahealth. The reference laboratory serving both of them may be on Sunquest. The post-acute facility accepting discharges from the hospital may be on PointClickCare. The small primary care practice referring patients to all of them may be on a legacy system that was installed fifteen years ago and has not been meaningfully updated since.
Fax works across all of those environments. It does not require a shared platform, a common integration standard, a vendor relationship, or a technical implementation on either end beyond a fax number. When a physician needs to send a referral to a specialist they have never worked with before, at a practice they have never contacted before, fax is the channel that works without any setup.
That cross-organizational interoperability is the core reason fax persists. Every alternative, whether Direct messaging, EHR-to-EHR interfaces, or API-based data exchange, requires both parties to be on compatible platforms and to have completed some form of technical onboarding. Fax requires neither. The universality of fax is not a technical limitation. It is a feature that no current alternative fully replicates.
What HIPAA Has to Do With It
HIPAA’s Security Rule requires that electronic protected health information be transmitted using appropriate safeguards. Fax, when transmitted through a compliant platform with encryption and delivery confirmation, satisfies those requirements. Email, despite widespread use, does not satisfy HIPAA’s technical safeguard requirements without additional encryption and access controls that many organizations have not fully implemented.
For organizations transmitting PHI externally, to providers, payers, laboratories, and post-acute facilities outside their own network, fax through a HIPAA-compliant platform is often the most straightforward compliant transmission option available. It does not require the receiving organization to have implemented a specific security standard. The encryption and audit trail live at the sending platform level.
The FAQ Friday post on what HIPAA actually requires for secure document transmission covers those requirements in more detail.
Volume Has Not Declined the Way Predictions Suggested
Industry predictions throughout the 2010s suggested that fax volume in healthcare would decline sharply as EHR adoption increased. EHR adoption did increase dramatically under the HITECH Act and Meaningful Use programs. Fax volume did not decline proportionally. In many organizations, EHR adoption increased fax volume because the EHR made it easier to generate and send documents that previously required manual preparation.
Prior authorization workflows, referral management, lab result delivery to community providers, discharge documentation, and care transition communications all generate fax volume that increased alongside EHR adoption rather than decreasing. The EHR created more structured, more complete documentation. Fax remained the channel for moving that documentation outside the organization.
What Modern Fax Infrastructure Actually Looks Like
The fax infrastructure that persists in healthcare today is not the fax machine in the corner or the aging server in the data center running software that has not been updated since 2012. For organizations that have modernized, fax infrastructure looks like Lane’s Passport platform or Fax 2.0: a cloud-based or software-based enterprise platform with workgroup routing, delivery confirmation, real-time monitoring through the Enterprise Status Manager, integration with EHR and LIS systems, and a full audit trail for every transmission.
That infrastructure does not look like what most people imagine when they think of fax. It looks like a critical communication platform that happens to use fax as its transmission protocol because fax is the protocol that reaches every organization in the healthcare ecosystem regardless of their technology stack.
The question for healthcare organizations in 2026 is not whether to use fax. The question is whether the fax infrastructure they are running is modern enough to meet the reliability, compliance, and visibility requirements of the workflows that depend on it.
