The race to eliminate healthcare faxes is officially on, but technology alone cannot fix a broken insurer approval system.

For decades, the fax machine has remained the stubborn gatekeeper of American medicine. Doctors waste hours chasing insurers for permission to treat patients, leading to dangerous delays. Now, Epic is rolling out its Coverage Requirements Discovery API to bypass this manual bottleneck entirely.

Four health systems—including Ochsner Health and Denver Health—are the first to deploy the tool. They are attempting to replace phone calls with instant, electronic checks.

The regulatory push

This early rollout is a defensive maneuver. A federal mandate looms on January 1, 2027, requiring electronic prior authorization across the industry. By partnering early with major payers like UnitedHealthcare and Aetna, Epic is trying to set the industry standard before regulators force everyone’s hand.

Sixteen additional payers are currently testing the tool.

The real bottleneck

But automating the request does not guarantee an approval. The underlying tension in healthcare is not just about slow communication; it is about rising insurer denial rates and strict coverage rules.

If insurers use these automated pipelines to issue instant denials, patients gain nothing. Speeding up a broken process does not fix the care deficit.

The true test of this API is whether it reduces administrative friction or simply accelerates the rejection rate. For now, it is a crucial infrastructure test. It proves that EHRs and insurers can talk to each other in real time, but the power dynamic between providers and payers remains unchanged.
