description: The US Core Observation Pregnancy Intent Profile inherits from the FHIR [Observation](https://hl7.org/fhir/R4/observation.html) resource; refer to it for scope and usage definitions. This profile meets the requirements of the U.S. Core Data for Interoperability (USCDI) *Pregnancy Status* Data Element. This profile sets minimum expectations for the Observation resource to record, search, and fetch the patient's intention to become pregnant. 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: USCoreObservationPregnancyIntentProfile type: Observation elements: status: {mustSupport: true, index: 0} category: mustSupport: true index: 1 slicing: rules: open discriminator: - {path: $this, type: value} min: null slices: SocialHistory: match: coding: - {code: social-history, system: 'http://terminology.hl7.org/CodeSystem/observation-category'} schema: mustSupport: true pattern: type: CodeableConcept value: coding: - {code: social-history, system: 'http://terminology.hl7.org/CodeSystem/observation-category'} index: 2 min: 0 max: 1 code: short: Pregnancy Status mustSupport: true pattern: type: CodeableConcept value: coding: - {code: 86645-9, system: 'http://loinc.org'} index: 3 subject: type: Reference mustSupport: true refers: ['http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient'] index: 4 effectiveDateTime: {mustSupport: true, index: 5} performer: type: Reference short: '𝗔𝗗𝗗𝗜𝗧𝗜𝗢𝗡𝗔𝗟 𝗨𝗦𝗖𝗗𝗜: Who is responsible for the observation' refers: ['http://hl7.org/fhir/StructureDefinition/PractitionerRole', 'http://hl7.org/fhir/us/core/StructureDefinition/us-core-careteam', 'http://hl7.org/fhir/us/core/StructureDefinition/us-core-organization', 'http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient', 'http://hl7.org/fhir/us/core/StructureDefinition/us-core-practitioner', 'http://hl7.org/fhir/us/core/StructureDefinition/us-core-relatedperson'] index: 6 valueCodeableConcept: type: CodeableConcept short: Coded Responses from Pregnancy Intent Value Set binding: {strength: extensible, valueSet: 'http://cts.nlm.nih.gov/fhir/ValueSet/2.16.840.1.113762.1.4.1166.22'} mustSupport: true index: 7 package_version: 8.0.0-ballot class: profile kind: resource url: http://hl7.org/fhir/us/core/StructureDefinition/us-core-observation-pregnancyintent base: http://hl7.org/fhir/StructureDefinition/Observation version: 8.0.0-ballot required: [effectiveDateTime, subject, valueCodeableConcept]
