ServiceRequest

Overview

The ServiceRequest resource is used to record the details of requests for procedures, diagnostic investigations, referrals, consults, and other services to be performed on or for a patient. ServiceRequests can be used to share relevant information required to support a referral or a transfer of care request from one practitioner or organization to another. Examples of service requests include diagnostic tests, imaging studies, specialist referrals, physical therapy, home health services, and other healthcare services.

Each ServiceRequest has the following elements:

  • a status
  • an intent code indicating whether the request is a proposal, plan, or order.
  • a code defining what is being requested
  • a patient

Profile specific implementation guidance

  • The ServiceRequest.category binding Must Support, at a minimum, the US Core ServiceRequest Category Codes. However, this valueset can be treated as extensible, and other category codes can be used instead.
  • The ServiceRequest.code valueset is broad to accommodate a wide variety of use cases andSHOULDbe constrained to a subset for a particular use case or domain. (for example, LOINC for laboratory orders.)
  • The ServiceRequest resource can communicate the reason or indication for referral or consultation using either a code in ServiceRequest.reasonCode or a reference using ServiceRequest.reasonReference.
    • As documented here, when using ServiceRequest.reasonReference, the referenced resources SHOULD be a US Core Profile.
  • See the Screening and Assessments guidance page for more information when exchanging Social Determinants of Health (SDOH) Service Requests.

This resource conforms to USCDI V3 profile for Procedure - refer to StructureDefinition US Core ServiceRequest. ServiceRequest response will be provided in JSON (refers to Capability Statement) format as per FHIR standard R4 version.

ServiceRequest must support these elements:

  • status
  • intent
  • category
    • category:us-core

The following search parameters and search parameter combinations SHALL be supported:

The syntax used to describe the interactions is described here.

GET [base url]/ServiceRequest?patient={Type/}[id]

SHALL support searching using the combination of the patient and category search parameters:

GET [base url]/ServiceRequest?patient={Type/}[id]&category={system|}[code]
