Request a patient's medication history via the Surescripts Medication History API

Steps

1. Obtain Surescripts network credentials and a signed trading partner agreement; Surescripts Medication History is accessible only to credentialed participants (EHRs, PBMs, health systems)
2. Construct a medication history request using the NCPDP SCRIPT MedicationHistoryRequest message type, supplying patient demographics (name, date of birth, gender, zip code) and your organization's NPI and NCPDP sender ID
3. Transmit the request to the Surescripts endpoint over the required secure transport (typically HTTPS with mutual TLS using YOUR_CERT and YOUR_KEY) and include the required message header fields
4. Parse the MedicationHistoryResponse which returns a structured list of fill records, each containing drug name, NDC, fill date, quantity dispensed, days supply, prescriber NPI, and dispensing pharmacy NCPDP ID
5. Reconcile returned fill records against the patient's current medication list in your system, flagging discrepancies or unreported medications for clinical review
6. Audit log the request and response including patient identity, requesting user, and timestamp to satisfy Surescripts audit requirements and HIPAA access logging obligations
