Why CRD is the starting point for seamless prior authorization

Key Players

Details

This article addresses the common delays in prior authorization processes—such as unclear requirements or incomplete documentation—by introducing CRD. Developed under the HL7 Da Vinci project, CRD is a FHIR Implementation Guide designed to provide providers with real-time visibility into payer rules right inside their workflow. It forms part of the larger electronic prior authorization (ePA) ecosystem, working alongside Documentation Templates and Rules (DTR) and Prior Authorization Support (PAS) to create an end-to-end digital loop. Technically, CRD utilizes CDS Hooks to surface payer-specific coverage rules in real time. This allows providers to determine if a service is covered, whether prior authorization is needed, and what documentation will be required—all without leaving their Electronic Health Record (EHR). Compliance with standards like CMS-0057-F mandates the implementation of primary hooks such as Appointment Book, Orders Sign, and Order Dispatch. For CRD to function effectively, payers must configure their services to return complete data responses. This requires defining specific data elements (e.g., Coverage status: covered | not-covered; Prior authorization status: no-auth | auth-needed) and ensuring client systems prefetch the necessary FHIR resources. Ultimately, by providing immediate, reliable coverage guidance at the moment of care, CRD transforms a historically frustrating process into a streamlined, real-time operation, laying the foundation for compliance.
