RTPB
Real-Time Prescription Benefit
RTPB surfaces patient-specific drug coverage and out-of-pocket cost inside the prescribing workflow, so clinicians can pick affordable, covered medications at the point of care.
Real-Time Prescription Benefit (RTPB) lets a prescriber see a patient's actual drug coverage, expected out-of-pocket cost, formulary status, and covered alternatives at the moment they are writing a prescription — rather than discovering a problem when the patient is at the pharmacy counter.
The current transaction standard is NCPDP RTPB v13, and it is converging with the CARIN Real-Time Pharmacy Benefit Check (RTPBC) FHIR implementation guide, aligning pharmacy benefit surfacing with the broader FHIR ecosystem on a timeline that overlaps the CMS-0057-F window.
RTPB is high-value because it directly affects adherence and cost: when a covered, affordable alternative is surfaced in workflow, patients are more likely to fill and stay on therapy.
