ServiceRequest

Conformance Expectation: SHALL

Resource Specific Documentation:

• The Must Support ServiceRequest.category is bound, at a minimum, to the [US Core ServiceRequest Category Codes], and other category codes can be used. API consumers can query by category when accessing patient information. For the USCDI Laboratory Order, Imaging Order, Clinical Test Order, and Procedure Order Data Elements, implementers SHOULD use the corresponding category codes listed in the table below. For example, laboratory orders would have the category code "108252007" (Laboratory procedure).

  |USCDI Order Data Element|Category Codes| |---|---| |Laboratory Order| 108252007 Laboratory procedure (procedure)| |Imaging Order|363679005 Imaging (procedure)| |Clinical Test Order|386053000 Evaluation procedure (procedure), 410606002 Social service procedure (procedure), or 387713003 Surgical procedure (procedure)| |Procedure Order|386053000 Evaluation procedure (procedure), 410606002 Social service procedure (procedure), or 387713003 Surgical procedure (procedure)|

• The ServiceRequest.code value set is broad to accommodate a wide variety of use cases and SHOULD be constrained to a subset for a particular use case or domain. These value sets contain concepts that span many use cases and are not bound to any USCDI Data Element. However, the table below identifies additional value set bindings for the USCDI Laboratory Order, Imaging Order and Clinical Test Order Data Elements. Implementers SHOULD conform to the binding strengths listed for each USCDI Order context. For example, laboratory orders are extensibly bound to the LOINC Common Laboratory Orders Value Set. Note that the USCDI Class Procedure Order Data Element has no additional binding.

  |USCDI Order Data Element|Additional Binding|Binding Strength|Comments| |---|---|---|---| |Laboratory Order|LOINC Common Laboratory Orders Value Set|extensible|The LOINC Common Laboratory Orders Value Set is a "starter set" for mapping commonly used laboratory orders. It does not attempt to include all possible laboratory order codes. For additional information on LOINC Common Laboratory Orders Value Set, refer to www.loinc.org/usage/orders.| |Imaging Order|LOINC Radiology Codes|preferred|The LOINC Radiology Codes include all imaging codes minus concepts that are deprecated or discouraged.| |Clinical Test Order|LOINC Clinical Test Codes|example|LOINC Clinical Test Codes include all non-laboratory and non-imaging clinical test codes|

• *Servers and Clients SHALL support both US Core ServiceRequest and US Core Procedure Profiles for communicating the reason or justification for a referral as Additional USCDI Requirements. Typically, the reason or justification for a referral or consultation is communicated through Procedure.basedOn linking the Procedure to the US Core ServiceRequest Profile that includes either ServiceRequest.reasonCode or ServiceRequest.reasonReference.
