MedicationRequest is a base FHIR Resource ( JSON example)
Commonly available via US Core MedicationRequest Profile

MedicationRequest is a FHIR Resource that describes an order or request for both supply of the medication and the instructions for administration of the medication to a patient.

Accessing a patient's medications can aid in workflows such as:

Working with the patient to ensure adherence to the medication protocol
Understanding a patient’s current medications to prevent drug-to-drug interactions
Advising the patient switch to generic medications to reduce overall out-of-pocket cost

Many payers make this available in a basic form derived from a patient's claims, but some also provide a more detailed view of the patient's medication requests if they have a more robust provider-payer clinical data exchange, such as quality measures.

#Search parameters

The full list of search parameters can be found here. Some of the most important are:

Parameters

patient: string; The ID of the patient for whom the medication was requested. We recommend using this search parameter along with the $PATIENT_ID wildcard
status: string; The status of the medication request.
code: string; The code of the medication that was requested. This is typically an NDC or RxNorm code.

#Sample request

While some servers may support a resource-level search without any parameters, not all do. We recommend using the format below with the patient ID via the $PATIENT_ID wildcard as a search parameter.

This is a sample request using curl
