description: The US Core Device Profile inherits from the FHIR [Device](https://hl7.org/fhir/R4/device.html) resource; refer to it for scope and usage definitions. This profile meets the requirements of the U.S. Core Data for Interoperability (USCDI) *Unique Device Identifier - Implantable* Data Element. It sets minimum expectations for the Device resource to record, search, and fetch UDI information associated with a patient's implantable device(s). It specifies which core elements, extensions, vocabularies, and value sets **SHALL** be present in the resource and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption. package_name: hl7.fhir.us.core derivation: constraint name: USCoreImplantableDeviceProfile type: Device elements: udiCarrier: mustSupport: true index: 0 elements: deviceIdentifier: {mustSupport: true, index: 1} carrierHRF: {mustSupport: true, index: 2} required: [deviceIdentifier] distinctIdentifier: {mustSupport: true, index: 3} manufactureDate: {mustSupport: true, index: 4} expirationDate: {mustSupport: true, index: 5} lotNumber: {mustSupport: true, index: 6} serialNumber: {mustSupport: true, index: 7} type: binding: {strength: extensible, valueSet: 'http://hl7.org/fhir/ValueSet/device-kind'} mustSupport: true index: 8 patient: type: Reference mustSupport: true refers: ['http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient'] index: 9 package_version: 8.0.0-ballot class: profile kind: resource url: http://hl7.org/fhir/us/core/StructureDefinition/us-core-implantable-device base: http://hl7.org/fhir/StructureDefinition/Device version: 8.0.0-ballot required: [type, patient]
