The US Core Medication Profile inherits from the FHIR Medication resource; refer to it for scope and usage definitions. This profile sets minimum expectations for the Medication resource to record, search, and fetch medications associated with a patient. When referencing a medication, the MedicationRequest resource can use a code or refer to this profile. It specifies which core elements, extensions, vocabularies, and value sets SHALL be present and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.

Example Usage Scenarios:

Queries on Medication resources are expected to be within the context of a MedicationRequest resource query. The following are example usage scenarios for the US Core Medication profile:

  • Read Medication resources referenced in MedicationRequest resources.

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 Medication Must Have:

  1. A medication code

Profile Specific Implementation Guidance:

  • RXNorm concepts are defined as an extensible binding. USCDI recommends the National Drug Codes (NDC) as an optional terminology. They can be supplied as an additional coding element.
  • Since the binding is extensible when a code is unavailable, just text is allowed.
  • When the medication is compounded and is a list of ingredients, the code is still present and may contain only the text.

Notes:

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 patients.

US Core Scopes

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

No required search criteria for us-core-medication profile.
