1. ServiceRequest
Definition | A record of a request for service such as diagnostic investigations, treatments, or operations to be performed.
Control | 0..*
Summary | false
Alternate Names | diagnostic request, referral, referral request, transfer of care request
Invariants | Defined on this element dom-2: If the resource is contained in another resource, it SHALL NOT contain nested Resources (: contained.contained.empty()) dom-3: If the resource is contained in another resource, it SHALL be referred to from elsewhere in the resource or SHALL refer to the containing resource (: contained.where((('#'+id in (%resource.descendants().reference | %resource.descendants().as(canonical) | %resource.descendants().as(uri) | %resource.descendants().as(url))) or descendants().where(reference = '#').exists() or descendants().where(as(canonical) = '#').exists() or descendants().where(as(canonical) = '#').exists()).not()).trace('unmatched', id).empty()) dom-4: If a resource is contained in another resource, it SHALL NOT have a meta.versionId or a meta.lastUpdated (: contained.meta.versionId.empty() and contained.meta.lastUpdated.empty()) dom-5: If a resource is contained in another resource, it SHALL NOT have a security label (: contained.meta.security.empty()) dom-6: A resource should have narrative for robust management (: text.`div`.exists()) prr-1: orderDetail SHALL only be present if code is present (: orderDetail.empty() or code.exists())
2. ServiceRequest.implicitRules
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Control | 0..1
Type | uri
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
3. ServiceRequest.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Control | 0..*
Type | Extension
Is Modifier | true
Summary | false
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.
Alternate Names | extensions, user content
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
4. ServiceRequest.identifier
Definition | Identifiers assigned to this order instance by the orderer and/or the receiver and/or order fulfiller.
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*
Type | Identifier
Must Support | true
Summary | true
Comments | The identifier.type element is used to distinguish between the identifiers assigned by the orderer (known as the 'Placer' in HL7 v2) and the producer of the observations in response to the order (known as the 'Filler' in HL7 v2). For further discussion and examples see the resource notes section below.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
5. ServiceRequest.status
Definition | The status of the order.
Control | 1..1
Binding | The codes SHALL be taken from RequestStatus The status of a service order.
Type | code
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Comments | The status is generally fully in the control of the requester - they determine whether the order is draft or active and, after it has been activated, competed, cancelled or suspended. States relating to the activities of the performer are reflected on either the corresponding event (see Event Pattern for general discussion) or using the Task resource.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. ServiceRequest.intent
Definition | Whether the request is a proposal, plan, an original order or a reflex order.
Control | 1..1
Binding | The codes SHALL be taken from RequestIntent The kind of service request.
Type | code
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Must Support | true
Summary | true
Comments | This element is labeled as a modifier because the intent alters when and how the resource is actually applicable.
Fixed Value | proposal
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. ServiceRequest.doNotPerform
Definition | Set this to true if the record is saying that the service/procedure should NOT be performed.
Control | 0..1
Type | boolean
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Requirements | Used for do not ambulate, do not elevate head of bed, do not flush NG tube, do not take blood pressure on a certain arm, etc.
Comments | In general, only the code and timeframe will be present, though occasional additional qualifiers such as body site or even performer could be included to narrow the scope of the prohibition. If the ServiceRequest.code and ServiceRequest.doNotPerform both contain negation, that will reinforce prohibition and should not have a double negative interpretation.
Meaning if Missing | If missing, the request is a positive request e.g. "do perform"
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
8. ServiceRequest.code
Definition | A code that identifies a particular service (i.e., procedure, diagnostic investigation, or panel of investigations) that have been requested.
Control | 0..1
Binding | For example codes, see Population Screening Follow-up Advice Value Set For example codes, see ProcedureCodes(SNOMEDCT)
Type | CodeableConcept
Must Support | true
Summary | true
Alternate Names | service requested
Comments | Many laboratory and radiology procedure codes embed the specimen/organ system in the test order name, for example, serum or serum/plasma glucose, or a chest x-ray. The specimen might not be recorded separately from the test code.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
9. ServiceRequest.subject
Definition | On whom or what the service is to be performed. This is usually a human patient, but can also be requested on animals, groups of humans or animals, devices such as dialysis machines, or even locations (typically for environmental scans).
Control | 1..1
Type | Reference(BePatient|Patient|Group|Location|Device)
Must Support | true
Summary | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
10. ServiceRequest.reasonReference
Definition | Indicates another resource that provides a justification for why this service is being requested. May relate to the resources referred to in `supportingInfo`.
Control | 0..*
Type | Reference(Condition|Observation|DiagnosticReport|DocumentReference)
Must Support | true
Must Support Types | No must-support rules about the choice of types/profiles
Summary | true
Comments | This element represents why the referral is being made and may be used to decide how the service will be performed, or even if it will be performed at all. To be as specific as possible, a reference to Observation or Condition should be used if available. Otherwise when referencing DiagnosticReport it should contain a finding in `DiagnosticReport.conclusion` and/or `DiagnosticReport.conclusionCode`. When using a reference to DocumentReference, the target document should contain clear findings language providing the relevant reason for this service request. Use the CodeableConcept text element in `ServiceRequest.reasonCode` if the data is free (uncoded) text as shown in the CT Scan example.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
11. ServiceRequest.bodySite

Control | 0..*
Binding | For example codes, see PopulationScreening Body Site Value Set For example codes, see SNOMEDCTBodyStructures
Type | CodeableConcept
Must Support | true
Summary | true
Requirements | Knowing where the procedure is performed is important for tracking if multiple sites are possible.
Alternate Names | location
Comments | Only used if not implicit in the code found in ServiceRequest.code. If the use case requires BodySite to be handled as a separate resource instead of an inline coded element (e.g. to identify and track separately) then use the standard extension procedure-targetBodyStructure.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))

Guidance on how to interpret the contents of this table can be found here.

1. ServiceRequest
Definition | A record of a request for service such as diagnostic investigations, treatments, or operations to be performed.
Control | 0..*
Summary | false
Alternate Names | diagnostic request, referral, referral request, transfer of care request
2. ServiceRequest.id
Definition | The logical id of the resource, as used in the URL for the resource. Once assigned, this value never changes.
Control | 0..1
Type | id
Summary | true
Comments | The only time that a resource does not have an id is when it is being submitted to the server using a create operation.
3. ServiceRequest.meta
Definition | The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.
Control | 0..1
Type | Meta
Summary | true
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
4. ServiceRequest.implicitRules
Definition | A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.
Control | 0..1
Type | uri
Is Modifier | true
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Comments | Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
5. ServiceRequest.language
Definition | The base language in which the resource is written.
Control | 0..1
Binding | The codes SHOULD be taken from CommonLanguages A human language
Additional Bindings | Purpose
AllLanguages | Max Binding
Type | code
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | false
Comments | Language is provided to support indexing and accessibility (typically, services such as text to speech use the language tag). The html language tag in the narrative applies to the narrative. The language tag on the resource may be used to specify the language of other presentations generated from the data in the resource. Not all the content has to be in the base language. The Resource.language should not be assumed to apply to the narrative automatically. If a language is specified, it should it also be specified on the div element in the html (see rules in HTML5 for information about the relationship between xml:lang and the html lang attribute).
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
6. ServiceRequest.text
Definition | A human-readable narrative that contains a summary of the resource and can be used to represent the content of the resource to a human. The narrative need not encode all the structured data, but is required to contain sufficient detail to make it "clinically safe" for a human to just read the narrative. Resource definitions may define what content should be represented in the narrative to ensure clinical safety.
Control | 0..1
Type | Narrative
Summary | false
Alternate Names | narrative, html, xhtml, display
Comments | Contained resources do not have narrative. Resources that are not contained SHOULD have a narrative. In some cases, a resource may only have text with little or no additional discrete data (as long as all minOccurs=1 elements are satisfied). This may be necessary for data from legacy systems where information is captured as a "text blob" or where text is additionally entered raw or narrated and encoded information is added later.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
7. ServiceRequest.contained
Definition | These resources do not have an independent existence apart from the resource that contains them - they cannot be identified independently, and nor can they have their own independent transaction scope.
Control | 0..*
Type | Resource
Summary | false
Alternate Names | inline resources, anonymous resources, contained resources
Comments | This should never be done when the content can be identified properly, as once identification is lost, it is extremely difficult (and context dependent) to restore it again. Contained resources may have profiles and tags In their meta elements, but SHALL NOT have security labels.
8. ServiceRequest.extension
Definition | May be used to represent additional information that is not part of the basic definition of the resource. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.
Control | 0..*
Type | Extension
Summary | false
Alternate Names | extensions, user content
Comments | There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count())) ext-1: Must have either extensions or value[x], not both (: extension.exists() != value.exists())
9. ServiceRequest.modifierExtension
Definition | May be used to represent additional information that is not part of the basic definition of the resource and that modifies the understanding of the element that contains it and/or the understanding of the containing element's descendants. Usually modifier elements provide negation or qualification. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer is allowed to define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension. Applications processing a resource are required to check for modifier extensions. Modifier extensions SHALL NOT change the meaning of any elements on Resource or DomainResource (including cannot change the meaning of modifierExtension itself).
Control | 0..*
Type | Extension
Is Modifier | true
Summary | false
Requirements | Modifier extensions allow for extensions that cannot be safely ignored to be clearly distinguished from the vast majority of extensions which can be safely ignored. This promotes interoperability by eliminating the need for implementers to prohibit the presence of extensions. For further information, see the definition of modifier extensions.

10. ServiceRequest.identifier
Definition | Identifiers assigned to this order instance by the orderer and/or the receiver and/or order fulfiller.
Note | This is a business identifier, not a resource identifier (see discussion)
Control | 0..*
Type | Identifier
Must Support | true
Summary | true
Comments | The identifier.type element is used to distinguish between the identifiers assigned by the orderer (known as the 'Placer' in HL7 v2) and the producer of the observations in response to the order (known as the 'Filler' in HL7 v2). For further discussion and examples see the resource notes section below.

Control | 0..*
Type | canonical(ActivityDefinition|PlanDefinition)
Primitive Value | This primitive element may be present, or absent, or replaced by an extension
Summary | true
Comments | Note: This is a business identifier, not a resource identifier (see discussion). It is best practice for the identifier to only appear on a single resource instance, however business practices may occasionally dictate that multiple resource instances with the same identifier can exist - possibly even with different resource types. For example, multiple Patient and a Person resource instance might share the same social insurance number.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))
12. ServiceRequest.instantiatesUri

Control | 0..1
Type | Identifier
Summary | true
Requirements | Some business processes need to know if multiple items were ordered as part of the same "requisition" for billing or other purposes.
Alternate Names | grouperId, groupIdentifier
Comments | Requests are linked either by a "basedOn" relationship (i.e. one request is fulfilling another) or by having a common requisition. Requests that are part of the same requisition are generally treated independently from the perspective of changing their state or maintaining them after initial creation.
Invariants | Defined on this element ele-1: All FHIR elements must have a @value or children (: hasValue() or (children().count() > id.count()))

Type | Reference(Practitioner|PractitionerRole|Organization|CareTeam|HealthcareService|Patient|Device|RelatedPerson)
Summary | true
Alternate Names | request recipient
Comments | If multiple performers are present, it is interpreted as a list of alternative performers without any preference regardless of order. If order of preference is needed use the request-performerOrder extension. Use CareTeam to represent a group of performers (for example, Practitioner A and Practitioner B).

Binding | For example codes, see ProcedureReasonCodes Diagnosis or problem codes justifying the reason for requesting the service investigation
Type | CodeableConcept
Summary | true
Comments | This element represents why the referral is being made and may be used to decide how the service will be performed, or even if it will be performed at all. Use `CodeableConcept.text` element if the data is free (uncoded) text as shown in the CT Scan example.

Must Support | true
Must Support Types | No must-support rules about the choice of types/profiles
Summary | true
Comments | This element represents why the referral is being made and may be used to decide how the service will be performed, or even if it will be performed at all. To be as specific as possible, a reference to Observation or Condition should be used if available. Otherwise when referencing DiagnosticReport it should contain a finding in `DiagnosticReport.conclusion` and/or `DiagnosticReport.conclusionCode`. When using a reference to DocumentReference, the target document should contain clear findings language providing the relevant reason for this service request. Use the CodeableConcept text element in `ServiceRequest.reasonCode` if the data is free (uncoded) text as shown in the CT Scan example.

37. ServiceRequest.supportingInfo
Definition | Additional clinical information about the patient or specimen that may influence the services or their interpretations. This information includes diagnosis, clinical findings and other observations. In laboratory ordering these are typically referred to as "ask at order entry questions (AOEs)". This includes observations explicitly requested by the producer (filler) to provide context or supporting information needed to complete the order. For example, reporting the amount of inspired oxygen for blood gas measurements.

38. ServiceRequest.specimen
Definition | One or more specimens that the laboratory procedure will use.
Control | 0..*
Type | Reference(Specimen)
Summary | true
Comments | Many diagnostic procedures need a specimen, but the request itself is not actually about the specimen. This element is for when the diagnostic is requested on already existing specimens and the request points to the specimen it applies to. Conversely, if the request is entered first with an unknown specimen, then the Specimen resource points to the ServiceRequest.

39. ServiceRequest.bodySite
Definition | Anatomic location where the procedure should be performed. This is the target site.
Control | 0..*
Binding | For example codes, see PopulationScreening Body Site Value Set
Type | CodeableConcept
Must Support | true
Summary | true
Requirements | Knowing where the procedure is performed is important for tracking if multiple sites are possible.
Alternate Names | location
Comments | Only used if not implicit in the code found in ServiceRequest.code. If the use case requires BodySite to be handled as a separate resource instead of an inline coded element (e.g. to identify and track separately) then use the standard extension procedure-targetBodyStructure.

Summary | false
Comments | This might not include provenances for all versions of the request – only those deemed “relevant” or important. This SHALL NOT include the Provenance associated with this current version of the resource. (If that provenance is deemed to be a “relevant” change, it will need to be added as part of a later update. Until then, it can be queried directly as the Provenance that points to this version using _revinclude All Provenances should have some historical version of this Request as their subject.
