This implementation guide describes the CARIN for Digital Insurance Card (C4DIC) Framework, providing a set of resources that payers can display to consumers via a FHIR API. This implementation guide focuses on standardizing how data elements from the physical insurance card can be transmitted in a FHIR-based exchange, leveraging the Coverage resource as well as Patient and Organization resources. See the Table of Contents for more information.

The CARIN Alliance

The CARIN (Creating Access to Real-time Information Now through Consumer-Directed Exchange) Alliance is an HL7 FHIR Accelerator program which brings implementers together to advance the use of HL7 FHIR standards in health care. The CARIN Alliance Health Plan Workgroup was organized to develop a FHIR-based API that could be implemented by a consumer-facing application. The goal of the CARIN Alliance Health Plan Workgroup is to develop an agreed upon set of data fields to exchange with consumers and a FHIR-based implementation guide for health plans and consumer facing applications to use to implement the API.



This IG was developed using FHIR Shorthand syntax and the SUSHI tookit, a free, open source toolchain from the MITRE Corporation. Valuable guidance on FSH and assistance with the FHIR IG builds were provided by Corey Spears (MITRE) and Vince Van Dintel (Humana).
