Onyx Ranked #1 for Client Satisfaction in FHIR-Based Prior Authorization Solutions

Onyx Leads the 2025 Healthcare Interoperability Market with OnyxOS Platform

TAMPA, FLORIDA / ACCESSWIRE / December 17, 2024 / Black Book Research has identified Onyx as the highest-rated vendor in its 2025 survey on FHIR-based prior authorization interoperability solutions. The survey, which captured insights from 665 providers and 718 payers, highlights the importance of CMS-mandated HL7\u00ae FHIR\u00ae (Fast Healthcare Interoperability Resources) standards in modernizing healthcare data exchange.

The study underscores the essential role of FHIR-based APIs in optimizing prior authorization workflows, enabling organizations to improve operational efficiency, meet compliance requirements, and enhance patient outcomes. Under recent CMS mandates, payer organizations-including Medicare Advantage Plans, Medicaid Managed Care Organizations (MCOs), and Qualified Health Plans - are required to adopt FHIR standards to enhance data sharing and interoperability. These regulations aim to standardize, secure, and simplify the exchange of healthcare data across ecosystems.

"These CMS mandates represent a transformative advancement for the healthcare industry," said Doug Brown, Founder of Black Book Research. "FHIR standards provide a robust, technically sound framework for seamless system integration, improving the efficiency of prior authorization and claims workflows. By leveraging FHIR-based APIs, organizations achieve real-time, bidirectional data exchange, fostering provider collaboration while reducing administrative overhead. This shift supports the industry's broader transition to value-based care models."
