The CMS Medicare Plan Finder Is Coming for Your Provider Directory API — Are You Ready?

“If your provider directory API isn’t compliant and performant, your plan simply won’t show up in Medicare Plan Finder

By Mark Scrimshire, Chief Interoperability Officer, Onyx The days of static provider directories are numbered. CMS is building a National Provider Directory powered by FHIR-based APIs, and starting October 1, 2026, the Medicare Plan Finder will begin ingesting provider and facility data directly from Medicare Advantage plans’ publicly accessible Plan-Net APIs. If your API isn’t […]

Why Mortality Data Still Breaks Healthcare Operations, and How APIs Can Fix It 

By Mark Scrimshire, Chief Interoperability Officer, Onyx One of the most important signals in healthcare data is also one of the hardest to capture reliably: vital status.  Health plans, providers, and researchers rely on accurate mortality information for everything from risk adjustment and quality reporting to population health analytics. Yet in many operational systems, mortality data is […]

From Compliance to Revenue Intelligence 

From Compliance to Revenue Intelligence Why we built OnyxOS and how the InteropX integration makes intelligence operational

Why we built OnyxOS and how the InteropX integration makes intelligence operational  By Susheel Ladwa, CEO, Onyx  The Shift  For years, the interoperability conversation in healthcare has been about compliance. CMS mandates. API deadlines. Audit readiness.  Health plans have done the work. APIs are live. Data is moving. And for most organizations, the compliance question, can we connect?, has been answered.  But here is what […]

Putting Clinical Data to Work 

Putting Clinical data to work

Why your data foundation determines your intelligence ceiling Interoperability has made real progress. APIs are live, standards are mandated, and most payers have crossed the compliance threshold. The infrastructure question—can we connect?—has largely been answered.  The question now is harder: what does the data actually do?  For payers managing HEDIS, Stars performance, risk adjustment, and care gap closure, the answer […]

Portable Trust Credentials: Why Now and How to Get Started 

The technology is ready, the regulatory deadlines are real, and early adopters will cut costs while building trust portfolios that late entrants will struggle to match.

By Mark Scrimshire, Chief Interoperability Officer, Onyx In my previous article, I explained how verifiable connectedness works as a mechanism for portable trust in healthcare interoperability. Today I want to address the practical questions: Why is now the right time to act? What does adoption look like? And what’s the business case?  Why Now: The Convergence of Three Forces  Three forces are […]

How Verifiable Connectedness Solves Healthcare’s Trust Problem 

Trust shouldn’t have to be re-established from scratch every time organizations connect. When authorization is verifiable, trust can travel across the network.

By Mark Scrimshire, Chief Interoperability Officer, Onyx  In a recent article on Healthcare IT Today, I described the missing trust layer in CMS-0057 compliance. The problem is clear: payers and providers need to establish thousands of new API connections, but current trust establishment methods—spreadsheets, attestation forms, manual verification calls—don’t scale.  Today I want to explain how we solve this: by making connectedness […]

Where Payer-to-Payer Succeeds or Fails in Production 

When Payer-to-Payer is designed as an operational workflow, it becomes the foundation for everything that follows under CMS-0057.

What payer teams encounter once real data and scale are introduced  By Balaji Narayanan, Chief Product Officer, Onyx Payer-to-Payer Data Exchange is a CMS-0057 workflow designed to transfer clinical history between payers when members change health plans. When executed reliably at scale, it establishes consistent data movement and enables downstream use across quality, utilization management, and risk programs.  In […]

Provider Directories, Interoperability, and What Medicaid & MA Plans Can Learn from Real-World Connectivity: A Conversation with Defacto Health

By Mark Scrimshire, Chief Interoperability Officer, Onyx   Accurate, accessible provider directory data sits at the foundation of almost every function in our healthcare system: member access, network adequacy oversight, referral management, prior authorization automation, and CMS-driven transparency initiatives.

Spotlight on PTAC: Strengthening the Data Foundation Needed for True Patient Empowerment 

A National Focus on Patient and Data Empowerment  The Physician-Focused Payment Model Technical Advisory Committee (PTAC) centered the agenda of its recent public meeting on a unifying theme: how data and health IT can transparently empower consumers and better support providers. PTAC’s role as an advisory body to HHS positions it uniquely to surface the structural challenges preventing patients from fully benefiting from digital tools, coordinated […]
