Epic, Oracle and Cleveland Clinic Join CMS Prior Authorization Initiative

Posted 17 May 2026 · Updated 17 May 2026 · 3 min read

The Centers for Medicare and Medicaid Services has announced that Epic, Oracle Health, and Cleveland Clinic are among 29 organizations joining its Electronic Prior Authorization Acceleration initiative, signaling a major shift in how clinical teams will request and receive treatment approvals by 2027.

The CMS initiative moves prior authorization from paper forms and fax machines into real-time, interoperable digital pipelines before a mandatory January 2027 deadline. Early adopters commit to embedding electronic workflows directly into EHR systems, using standardized APIs to replace phone calls and faxes, and sharing implementation data with CMS to refine industry standards.

A total of 29 organizations across EHR vendors, providers, and health data networks have signed on as early adopters, including 9 major health systems. All participants must have electronic prior authorization workflows embedded in clinical systems ahead of the January 1, 2027 deadline for Medicare Advantage, Medicaid, and Marketplace plans.

Why Epic, Oracle and Cleveland Clinic's Participation Matters

By joining the pledge, Epic and Oracle Health signal that their core EHR platforms will support interoperable, end-to-end electronic prior authorization workflows for provider systems nationwide. Cleveland Clinic's inclusion reflects pressure from large health systems to cut delays in high-volume specialties where authorization backlogs have the most direct impact on patient care.

Early Adopters — Key Organizations

EHR Vendor

Epic

Epic's EHR — used by large health systems and community practices — can surface prior authorization requests directly inside clinician notes, eliminating workflow interruptions.

EHR Vendor

Oracle Health

Oracle's cloud and integration tools can connect prior authorization requests to payer decision engines in real time, reducing manual follow-up across clinical and administrative teams.

What This Means for Clinical Teams

If the initiative succeeds, clinical teams could see:

Faster approvals

API-driven exchanges may reduce routine request turnaround from days to hours, according to the CMS blog on moving prior authorization into the 21st century.

Fewer phone calls and faxes

Automated status tracking and embedded payer responses inside the EHR could significantly cut the time clinical staff spend chasing faxes and voicemails.

Better patient experience

Quicker decisions reduce treatment delays and coverage uncertainty, particularly for time-sensitive or urgent care where authorization backlogs most directly affect outcomes.

Implementation Challenges

Stakeholders warn that implementation will require careful mapping of clinical rules, payer-specific policies, and specialty workflows, particularly in oncology and advanced imaging. Smaller practices may also need IT support to integrate new tools without additional burden. Early-adopter sites will begin pilot testing over the next year, with CMS refining standards before broader rollout, according to LeadingAge.

The Bottom Line

Prior authorization has long been one of the most time-consuming and frustrating parts of clinical practice. The CMS initiative, backed by Epic, Oracle Health, and Cleveland Clinic, is the most concrete step toward fixing it. Whether it delivers on its promise depends on execution — but the participation of major EHR vendors and health systems makes this the most credible prior authorization reform effort to date.
