An ecosystem built to go further, faster

Availity · Data & Network

Onyx and Availity have partnered to deliver a comprehensive, out-of-the-box solution for CMS-0057 compliance — combining OnyxOS’s FHIR platform with Availity’s connections to over 95% of payers, 3M+ providers, and 2,000+ trading partners. The joint platform covers patient access, provider access, payer-to-payer exchange, and prior authorization APIs — production-ready, without building from scratch. 

"We've built this solution to go beyond compliance. By embedding FHIR-native APIs and real-time data exchange into payer workflows, we're laying the foundation for a more connected, efficient, and patient-centered healthcare system."

Sean Barrett · Chief Product Officer, Availity

Microsoft · Technology & Cloud

OnyxOS is jointly built with Microsoft on Azure — the same infrastructure behind CMS Blue Button 2.0. The partnership gives every OnyxOS deployment enterprise-grade cloud security, Azure Health Data Services integration, and native availability in the Azure Marketplace. Jointly developed, production-tested, and trusted at national scale. 

"OnyxOS not only meets CMS mandate requirements but exceeds them on all counts. Microsoft is proud to partner with Onyx in making the OnyxOS offering available in the Azure Marketplace."

Sam Robinson · Chief Health Plan Officer, US Health and Life Sciences, Microsoft

Veritas Data Research · Data & Network

Onyx and Veritas Data Research have partnered to deliver real-time mortality data directly into OnyxOS via FHIR — the first integration of its kind. Veritas’s Fact of Death index, sourced from 45,000+ public and private records, flows into OnyxOS as a standardized, automated feed. Health plans get mortality signals embedded in the same platform driving risk adjustment, payment integrity, and care gap programs. 

"We are eliminating the technical silos that prevent critical mortality data from reaching the point of need. By partnering with Onyx to leverage FHIR standards, we are making it easier than ever for payers and providers to maintain the integrity of their member and patient data."

Jason LaBonte · CEO, Veritas Data Research

Abacus Insights · Data & Network

Abacus Insights, the leader in data usability for payers, built their interoperability solution on OnyxOS — combining Abacus’s longitudinal patient record and data enrichment capabilities with OnyxOS’s FHIR APIs. The result is a single, unified solution that takes health plans from raw data to compliant, actionable intelligence — without two separate platforms to manage. 

"The partnership between Abacus Insights and Onyx unleashes the full power of interoperability for payers in a single solution, eliminating the need for them to undertake massive and costly internal development efforts."

Minal Patel, MD · Founder & CEO, Abacus Insights

Midato Health · Data & Network

Onyx and Midato Health have integrated Midato’s ShareApprove™ Consent Preference Management Platform with OnyxOS — enabling payers, Medicaid agencies, and MCOs to activate FHIR APIs with embedded, patient-directed consent flows. The joint solution supports CMS-Aligned Network goals and CMS-0057 compliance with consent management built in from the start. 

"Consent is the connective tissue in a person-centric, interoperable health network."

Carol Robinson · CEO, Midato Health

Mastek · Implementation & Integration

"Our FHIR Interoperable platform services partnership with Onyx decomplexifies healthcare mandates and compliance deadlines — improving star quality ratings and patient experiences and outcomes for healthcare CXOs."
