The US Core Medication Request Profile is based upon the core FHIR MedicationRequest Resource and meets the U.S. Core Data for Interoperability (USCDI) Medications requirements. The MedicationRequest resource can be used to record a patient’s medication prescription or order. This profile sets minimum expectations for the MedicationRequest resource to record, search, and fetch a patient’s medication to promote interoperability and adoption through common implementation. It identifies which core elements, extensions, vocabularies, and value sets SHALL be present in the resource and constrains the way the elements are used when using this profile. It provides the floor for standards development for specific use cases.

Example Usage Scenarios:

The following are example usage scenarios for the US Core-MedicationRequest profile. See the Medication List section for guidance on accessing a patient medications:

  • Fetching all medications that have been prescribed to a particular patient
  • Fetching all active medications that have been prescribed to particular patient
  • Fetching all medications that have been prescribed to particular patient during a particular encounter
  • Record or update medications that have been prescribed for a particular patient

Mandatory and Must Support Data Elements

The following data-elements must always be present (Mandatory definition) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.

Each MedicationRequest Must Have:

  1. a status
  2. an intent code
  3. a medication*
  4. a patient

Each MedicationRequest Must Support:

  1. the category (e.g., Discharge Medication)
  2. the reported flag or reference signaling that information is from a secondary source such as a patient
  3. the encounters
  4. a prescriber
  5. a date for when written
  6. the prescription Sig
  7. the amount dispensed and number of refills
  8. the dose and rate

Additional USCDI Requirements:

These Additional USCDI Requirements elements are not Mandatory or Must Support but are required for ONC Health IT certification testing and are included in the formal definition of the profile and the MedicationRequest examples.

  1. the reason or indication for the prescription*
  2. reported adherence to prescribed medication instructions*

* see guidance below

Profile Specific Implementation Guidance:

  • See the Medication List section for guidance on accessing a patient medications including over the counter (OTC) medication and other substances taken for medical and recreational use.
    • When recording “self-prescribed” medication, requester SHOULD be used to indicate the Patient or RelatedPerson as the prescriber.
  • *This Profile can represent a medication using a code or reference a Medication resource.
    • When using a code, RXNorm concepts are used. They are defined as an extensible binding to .medicationCodeableConcept. USCDI recommends the National Drug Codes (NDC) as an optional terminology. They can be supplied as an additional coding element.
      • Systems that primarily rely on NDC codes instead of RxNorm to represent medications can use the National Library of Medicine’s (NLM) NDC to RxNorm mappings to aid in translations.
    • When referencing a Medication resource in .medicationReference, the resource may be contained or an external resource.
    • The server systems are not required to support both a code and a reference, but SHALL support at least one of these methods.
    • If an external reference to a Medication resource is used, the server SHALL support the _include parameter for searching this element.
    • The client application SHALL support all methods.
  • The MedicationRequest resource can represent that information is from a secondary source using either a boolean flag or a reference using MedicationRequest.reportedReference.
    • Although both are marked as Must Support, the server system is not required to support both, but SHALL support at least one of these elements.
    • The client application SHALL support both elements.
  • *The MedicationRequest resource can communicate the reason or indication for treatment using either a code in MedicationRequest.reasonCode or a reference using MedicationRequest.reasonReference.
    • As documented here, when using MedicationRequest.reasonReference, the referenced Condition or Observation SHOULD be a US Core Profile.
  • Source EHR identifiers SHOULD be included to support deduplication across MedicationRequest resources. Exposing the EHR identifiers helps client applications identify duplicates.
  • Servers SHALL follow the guidance in the Medication List page and return all active Medications as MedicationRequest. It is always best practice to confirm this list with the Patient or Caregiver.

  • * This profile uses the US Core Medication Adherence Extension to report medication adherence. This extension communicates whether a medication has been consumed according to instruction.

    Quick Start


    Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile’s information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

    • See the Scopes Format section for a description of the SMART scopes syntax.
    • See the Search Syntax section for a description of the US Core search syntax.
    • See the General Requirements section for additional rules and expectations when a server requires status parameters.
    • See the General Guidance section for additional guidance on searching for multiple <patient user system>s.

    US Core Scopes

    Servers providing access to prescription data SHALL support these US Core SMART Scopes:

    Mandatory Search Parameters:

    1. SHALL support searching using the combination of the patient and intent search parameters:
      • including optional support for these _include parameters: MedicationRequest:medication
      • including support for OR search on intent (e.g.intent={system|}[code],{system|}[code],...)

      GET [base]/MedicationRequest?patient={Type/}[id]&intent=order,plan

      Example:

      1. GET [base]/MedicationRequest?patient=14676&intent=order,plan
      2. GET [base]/MedicationRequest?patient=14676&intent=order,plan&_include=MedicationRequest:medication

      Implementation Notes: Fetches a bundle of all MedicationRequest resources for the specified patient and intent code = order,plan (how to search by reference and how to search by token)

    2. SHALL support searching using the combination of the patient and intent and status search parameters:
      • including optional support for these _include parameters: MedicationRequest:medication
      • including support for OR search on intent (e.g.intent={system|}[code],{system|}[code],...)
      • including support for OR search on status (e.g.status={system|}[code],{system|}[code],...)

      GET [base]/MedicationRequest?patient={Type/}[id]&intent=order,plan&status={system|}[code]{,{system|}[code],...}

      Example:

      1. GET [base]/MedicationRequest?patient=1137192&intent=order,plan&status=active
      2. GET [base]/MedicationRequest?patient=1137192&intent=order,plan&status=active&_include=MedicationRequest:medication

      Implementation Notes: Fetches a bundle of all MedicationRequest resources for the specified patient and intent code = order,plan and status (how to search by reference and how to search by token)

    Optional Search Parameters:

    The following search parameter combinations SHOULD be supported:

    1. SHOULD support searching using the combination of the patient and intent and encounter search parameters:
      • including optional support for these _include parameters: MedicationRequest:medication
      • including support for OR search on intent (e.g.intent={system|}[code],{system|}[code],...)

      GET [base]/MedicationRequest?patient={Type/}[id]&intent=order,plan&encounter={Type/}[id]

      Example:

      1. GET [base]/MedicationRequest?patient=1137192&intent=order,plan&status=active&encounter=Encounter/123
      2. GET [base]/MedicationRequest?patient=1137192&intent=order,plan&status=active&&encounter=Encounter/123&_include=MedicationRequest:medication

      Implementation Notes: Fetches a bundle of all MedicationRequest resources for the specified patient and intent code = order,plan and encounter (how to search by reference and how to search by token)

    2. SHOULD support searching using the combination of the patient and intent and authoredon search parameters:
      • including optional support for these _include parameters: MedicationRequest:medication
      • including support for OR search on intent (e.g.intent={system|}[code],{system|}[code],...)
      • including support for these authoredon comparators: gt,lt,ge,le
      • including optional support for AND search on authoredon (e.g.authoredon=[date]&authoredon=[date]]&...)

      GET [base]/MedicationRequest?patient={Type/}[id]&intent=order,plan&authoredon={gt|lt|ge|le}[date]{&authoredon={gt|lt|ge|le}[date]&...}

      Example:

      1. GET [base]/MedicationRequest?patient=1137192&intent=order,plan&authoredon=ge2019-01-01T00:00:00Z
      2. GET [base]/MedicationRequest?patient=1137192&intent=order,plan&authoredon=ge2019-01-01T00:00:00Z&_include=MedicationRequest:medication

      Implementation Notes: Fetches a bundle of all MedicationRequest resources for the specified patient and intent code = order,plan and authoredon date (how to search by reference and how to search by token and how to search by date)
