Surescripts Eligibility and Formulary
Verifies patient pharmacy benefit eligibility and returns formulary and benefit coverage details so prescribers see coverage and coverage alternatives in workflow. Eligibility rides X12 270 request / 271 response exchange through the network; formulary rides the NCPDP Formulary and Benefit standard. Companion guides for both are published on the Surescripts Developer Portal; the machine-callable download surface is catalogued separately as the Formulary Download API.
