Short Description[edit | edit source]

CARIN Real-time Pharmacy Benefit Check (RTPBC) FHIR Implementation Guide

Long Description[edit | edit source]

Using Real-time Pharmacy Benefit Check (RTPBC), a patient can learn how their medications will be covered at the pharmacy, including out of pocket costs and coverage restrictions or requirements that might apply.

The communication flow consists of...

  • a request submitted by a consumer application that contains information about the patient, the prescription and their insurance coverage
  • a response from the patient's insurer that contains cost and coverage information for the requested product, alternative products, and different pharmacy options.

This IG defines FHIR profiles for resources representing...

  • the set of information provided in the RTPBC request that enables the insurer to locate the patient's membership details and determine coverage for the requested product. This includes profiles of Claim, Patient, Practitioner, Organization and MedicationRequest resources
  • the pricing and coverage information returned in the RTPBC response, using a profile of the ClaimResponse.

In addition, the guide identifies terminology to identify the referenced entities and aspects of insurance coverage.

Involved parties[edit | edit source]

The RTPBC IG is being authored by the CARIN Alliance in collaboration with the National Council for Prescription Drug Programs (NCPDP), HL7 Pharmacy and Financial Management workgroups.
