description: The Immunizations Section defines a patient's current immunization status and pertinent immunization history. The primary use case for the Immunization Section is to enable communication of a patient's immunization status. The section should include current immunization status, and may contain the entire immunization history that is relevant to the period of time being summarized. package_name: hl7.cda.us.ccda derivation: constraint name: ImmunizationsSection type: http://hl7.org/cda/stds/core/StructureDefinition/Section elements: nullFlavor: {short: 'If a required section contains no information, the @nullFlavor MAY be set to NI', index: 0} templateId: index: 1 slicing: rules: open discriminator: - {path: root, type: value} - {path: extension, type: value} min: 1 slices: section: match: {root: 2.16.840.1.113883.10.20.22.2.2.1, extension: '2015-08-01'} schema: _required: true index: 2 elements: root: pattern: {type: String, value: 2.16.840.1.113883.10.20.22.2.2.1} index: 3 extension: pattern: {type: String, value: '2015-08-01'} index: 4 required: [root, extension] extensions: {} code: short: Immunizations index: 5 elements: code: pattern: {type: Code, value: 11369-6} index: 6 codeSystem: pattern: {type: String, value: 2.16.840.1.113883.6.1} index: 7 required: [codeSystem, code] title: {index: 8} text: {index: 9} entry: short: If section/@nullFlavor is not present... index: 10 slicing: rules: open discriminator: - {path: substanceAdministration, type: profile} min: null slices: activity: match: {} schema: short: (USCDI) Immunizations array: true index: 11 elements: substanceAdministration: {type: 'http://hl7.org/cda/stds/core/StructureDefinition/SubstanceAdministration', index: 12} required: [substanceAdministration] package_version: 3.0.0-ballot class: logical kind: logical url: http://hl7.org/cda/us/ccda/StructureDefinition/ImmunizationsSection base: http://hl7.org/cda/stds/core/StructureDefinition/Section version: 3.0.0-ballot required: [text, title, templateId, code]
