Operon is the integration layer that wraps the UM, claims, member, and PA systems you already run and exposes them as one CMS-0057-F-conformant FHIR surface.

Provider-Payer Test Ready in weeks. No data-layer rebuild.

The Deadline Is Here

January 1, 2027 is firm.

Federal program participation is on the line.

86% of US payers scored an F on the April 2026 audit
Zero of audited payer FHIR endpoints meet the CMS-0057-F PAS spec
47% of providers expect to meet the deadline (was 69%)
33% of providers haven't started implementation

The Structural Problem

Why One Platform Can't Fix
CMS-0057-F for Multi-System Payers

Real payer stacks span multiple vendors: a UM platform, a claims system, a member portal, a PA platform, EHR feeds, clearinghouses. CMS-0057-F requires you to expose one coherent FHIR surface across all of them. WEDI's February 2026 survey identifies "delegated third parties struggling with system connectivity" as the #1 reported payer pain point.

Most CMS-0057-F vendors answer this by asking you to replace your data layer with theirs. For a multi-system payer that is a 12-to-18-month engagement, in cross-vendor coordination, on a 7-month calendar. Even when it ships, you've substituted one platform for another. The structural integration problem hasn't gone away.

Operon wraps the systems you already run. No retirements. Provider-Payer Test Ready in weeks.

What Operon Does

The Neutral Integration Layer
Above Your Existing CMS-0057-F Stack

We orchestrate what you already run into one conformant FHIR surface for your testing partners, and produce the public-reporting-ready evidence your compliance team will be asked for.

The Reality

CMS-0057-F Runs on a Stack

In production, compliance is delivered by a combination of platforms, vendors, and internal tools, including UM systems, claims platforms, member portals, PA workflows, FHIR servers, integration engines, prior-payer connectors. No single component covers the whole rule. Orchestration across them is the actual work, and it's the #1 reported payer pain in WEDI's February 2026 survey.

The Operon Angle

Operon Connects What You Already Run

We sit above the stack and connect it. Operon does not replace your UM platform, claims system, member portal, PA workflow, or FHIR server. For testing engagements, we connect through standard integration patterns (HL7 v2, X12, FHIR, REST, SFTP, message queues) and orchestrate the combined output as one CMS-0057-F-conformant FHIR surface across all six WEDI-tracked surfaces on Da Vinci IG 2.0 / 2.1 / 2.2 concurrently. Per-engagement isolated tenants. Cross-system provenance on every response.

What You Get

Two Outputs from One Engagement

For Your Testing Partners

Provider EHRs, third-party apps, prior-payer systems. Operon is one stable FHIR target across all six APIs, not a per-vendor scavenger hunt.

For Your Compliance Team

Every engagement ends with a public-reporting-ready report:

  • Per-resource conformance evidence vs the IG, plus a CapabilityStatement diff per supported IG version.
  • SLA telemetry, PAS 72-hour expedited / 7-day standard, Patient Access freshness, Payer-to-Payer round-trip, Provider Access export latency.
  • Public-reporting-ready CMS metric template, denial rates, response times, decision categories.
  • Cross-system provenance log, which underlying vendor answered each request, attributable in audit.

Industry Reality

The Cost and Complexity
Reality

The deadline is one half of the story. Cost uncertainty, vendor sprawl, and rollout preference are the other half. They're what makes wrapping the existing stack land instead of replacing it.

Vendor Evaluation

Three Questions to Ask
Any CMS-0057-F Vendor

Worth asking before you commit to a path. These are the trade-offs WEDI's February 2026 industry survey surfaces as the dominant readiness blockers.

Question 1

Do you have 12 to 18 months to replace your data layer?

Most plans do not. Platform-replacement engagements typically run 12 to 18 months from kickoff. The deadline is January 1, 2027. Operon reaches Provider-Payer Test Ready in weeks because we wrap your existing systems instead of replacing them.

Question 2

Do you want to retire UM, claims, member, or PA vendors you already pay?

Most plans do not. Operon sits in front of whichever combination you already run and exposes them as one CMS-0057-F-conformant FHIR surface. No retirements required.

Question 3

Can your compliance team prove conformance without your team rebuilding what already works?

With Operon, every engagement produces a public-reporting-ready conformance and readiness report scoped to the CMS metric template, plus per-resource pass/fail evidence against the IG.

Ready to Ship

Book a Call

30 minutes with someone from our team. We'll ask about the systems you already run, where you are on the CMS-0057-F calendar, and what testing you need to ship. No pitch deck, no pressure, no demo unless you ask.

Good Fit If You Are:

  • A covered payer planning CMS-0057-F testing windows against your existing UM, claims, member, or PA stack.
  • A provider, EHR, or third-party app vendor needing a tested payer counterparty to validate your integration.
  • A clearinghouse or prior-auth intermediary in a delegated workflow that needs a published testing target.
  • Anyone preparing for the January 1, 2027 deadline who wants conformance evidence, not slides.
