Patient Access API

Integration of the Digital Insurance Card With the CARIN Consumer Directed Payer Data Exchange (CARIN IG for Blue Button®) and Patient Access API

The widely adopted CARIN Blue Button IG supports the generation of FHIR Coverage resources to represent insurance coverage associated with adjudicated claims and encounters. The CARIN Digital Insurance Card IG supports the digital representation of a consumer’s insurance card. To enable broader interoperability and consumer usability, implementers may choose to generate both of these distinct Coverage resources.

This approach allows payers to leverage existing functionality from CARIN Blue Button and the resources in this IG to expose both claims-related coverage and insurance card coverage. Applications can query for both resources using standard FHIR search parameters (e.g., _profile, type, status) and present them in context. For example, a consumer-facing app may show the member’s digital insurance card alongside their Explanation of Benefits (EOBs), while a provider-facing system may use both resources to verify coverage and review recent claims during patient intake. This integration supports both consumer-facing (B2C) and provider-facing (B2B) workflows and enhances usability, transparency, and compliance with federal regulations.
