Fill a prior authorization fax form. Provide the patient’s plan identifiers (bin, pcn, group, member_id, state), a drug_slug (from /search_drugs), the icd10_diagnosis, plus patient, prescriber, and clinical-question data; the backend looks up the full drug profile (medication_strength, qty, day_supply, directions, route, etc.) from its internal drug catalog, resolves the correct PA form, and fills it. Returns a form ID and a signed URL to preview the filled PDF. Call Submit Prior Authorization with the ID to transmit the fax to the payer.
