Onyx Acquires InteropX
Advancing Interoperability and Prior Authorization.
Amplifying the Value of Clinical Data.
Ready to deliver interopability & ePA at scale
Electronic Prior Authorization has become a critical operational challenge for health plans. While CMS requirements have accelerated adoption, success depends on more than exposing APIs—it requires proven execution and the ability to use clinical data inside payer workflows.
Together, Onyx and InteropX expand delivery capacity and execution depth, helping health plans move from implementation to sustained operational impact across interoperability and prior authorization initiatives.
What We Deliver Together
More FHIR expertise. More delivery power.
Clinical Data, Ready to Use
AI-Assisted Workflows
Where clinical data creates operational value
Interoperability alone doesn’t deliver ROI. Value is realized when clinical data is trusted, prepared, and embedded directly into payer workflows.
By combining standards-based interoperability with clinical data readiness and AI-assisted processing, Onyx and InteropX help health plans apply clinical data across prior authorization, utilization management, risk, and quality—turning regulatory requirements into lasting operational capability.
What This Means For You
