Key Players
Details
Onyx, recognized as the leading platform provider for CMS Payer Interoperability and a 2025 Best in KLAS® winner, announced the acquisition of InteropX. This merger integrates InteropX's expertise in large-scale payer interoperability, IT transformation, and data-driven AI with Onyx’s existing capabilities. The combined strength enhances health plans' ability to advance interoperability through APIs like Electronic Prior Authorization (ePA) and Payer-to-Payer Data Exchange. By incorporating InteropX's deep expertise in FHIR-based exchange, AI-powered clinical document processing, and payer-centric services, Onyx can operationalize interoperability for both regulatory compliance and high-impact business use cases. This allows health plans to move beyond mere compliance and achieve a true 'Operational Advantage.' The combined platform enables the embedding of standardized clinical data (such as CDEX bundles, CCDAs, and FHIR resources) directly into workflows like prior authorization, utilization management, risk adjustment, and quality improvement. The technology supports bi-directional, payer-ready access to clinical data, reducing reliance on manual processes and enabling smarter, more data-driven decisions across the healthcare ecosystem.
