Don't guess where you stand with CMS-0057. Assess it.
With the January 1, 2027 CMS-0057 deadline approaching, now is the time to assess whether your roadmap is ready for the APIs, workflows, partner dependencies, and expanding mandates ahead.
Onyx CMS-0057 Readiness Check
For CMS-0057 and the expanding interoperability mandates around it.
Onyx has helped shape the CMS-0057 standards and guided health plans in bringing production-ready FHIR APIs to market. Today, we work with more than 50 payer organizations representing 55M covered lives, bringing practical experience across APIs, workflows, partner dependencies, and operational execution.
For most health plans, CMS-0057 work is already underway. The question now is whether those efforts are creating a foundation that can scale beyond the initial deadline.
CMS-0053-F claims attachments, Plan Net provider directory APIs, and the proposed CMS-0062-P expansion of prior authorization and related FHIR-based workflows are already broadening the interoperability roadmap. Health plans need a foundation that can support more data, more workflows, more partners, and more reuse across risk, quality, care, and payment.
Onyx’s complimentary, expert-led Readiness Check gives health plans a structured way to assess their current state in one week — including readiness across the required CMS-0057 APIs, key gaps, risks, partner dependencies, and practical next steps.

A Structured Assessment, Designed for Action
Our Readiness Check provides a structured assessment of your current state across the required CMS-0057 APIs, helping your team identify key gaps, risks, and next steps — and evaluate whether your approach can support broader priorities in risk, quality, care, and payment. It is designed as a focused, one-week engagement that works with your existing materials and avoids a lengthy discovery process.
What you'll receive
- A structured view of readiness across Patient Access, Provider Access, Payer-to-Payer, and Prior Authorization
- Key gaps and risks across APIs, workflows, and partner dependencies
- Practical recommendations and next steps to strengthen execution
- A clearer view of whether your approach is creating the right foundation for broader priorities in risk, quality, care, and payment
How it works
1. Kickoff conversation
We begin with a working session to understand your current CMS-0057 approach, priorities, and implementation status.
2. Structured assessment
Our team reviews your current state across the required APIs, workflows, and operational dependencies, using a consistent framework to assess readiness against core CMS-0057 requirements.
3. Tailored readiness report
Within one week, you receive a report outlining your current state, key gaps and risks, and practical next steps.
What this requires from your team
One 60-minute working session
We ask for a working session with the right business and technical stakeholders to understand your current approach and implementation status.
Existing documentation, if available
Implementation plans, architecture materials, or related documentation can help inform the assessment, but we can work with what you have.
A confidential review
We’ll put an NDA in place to support an appropriate review of your current state.
