About Us
Before OnyxOS was a platform, it was our point of view — that health data should be useful, not just exchanged. We're engineers, standards authors, and healthcare operators, and we've spent the last decade turning that belief into something our customers can run. The rest of this page is how we got here, and where we're taking it next.
OnyxOS is the payer intelligence platform that turns connected health data into intelligence across risk adjustment, quality and HEDIS, care management, and payment integrity — for 50+ health plans covering 1 in 6 Americans.
"Connected data is the biggest unused asset in American healthcare. Closing the gap between data that exists and data that works is why we built Onyx."
Onyx was built by the architects of modern payer interoperability — the team that built CMS Blue Button 2.0, authored the HL7 Da Vinci PDex standard that CMS-0057 is built on, and created the federal health data infrastructure that serves tens of millions of Americans today.
Connected health data has always been at the core of everything we build. OnyxOS takes that foundation further — getting clinical data from every provider, making it usable through a longitudinal patient record, and activating it across the workflows that drive payer performance: risk adjustment, quality and HEDIS, care management, and payment integrity.
That's what OnyxOS is today — and why we say "From data exchange to data intelligence." It's our history, and our direction.
