The real-time pharmacy benefit check (RTPBC) process involves a request from a consumer application used by a patient to either (a) the party that manages the pharmacy benefit portion of the patient's health insurance or (b) a party that serves as a source for typical and discount medication pricing information.

Resources used in the exchange

The consumer RTPBC request and response are accomplished using FHIR Claim and ClaimResponse resources in a "predetermination" (what-if) mode. Other FHIR® resources support the exchange by fleshing out patient, prescription, pharmacy and coverage information needed to determine accurate cost and coverage. An OperationOutcome communicates exception situations where a ClaimResponse cannot be returned.

Claim - Represents the RTPBC request. Uses the predetermination Claim.use mode

ClaimResponse - Represents the RTPBC response

Patient - Conveys the patient information needed for the exchange

Coverage - Conveys the patient's pharmacy benefit coverage IDs

MedicationRequest - Conveys the needed prescription information (a subset of what is present in a full prescription)
