US Core Implementation Guide, published by HL7 International / Cross-Group Projects. This guide is not an authorized publication; it is the continuous build for version 8.0.1 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/US-Core/ and changes regularly. See the Directory of published versions

## Resource Profile: US Core Procedure Profile

Official URL: http://hl7.org/fhir/us/core/StructureDefinition/us-core-procedure | Version: 8.0.1
Standards status: Trial-use | Maturity Level: 3 | Computable Name: USCoreProcedureProfile
Other Identifiers: OID:2.16.840.1.113883.4.642.40.2.42.53

The US Core Procedure Profile inherits from the FHIR Procedure resource; refer to it for scope and usage definitions. This profile meets the requirements of the U.S. Core Data for Interoperability (USCDI) Procedures Data Class. It sets minimum expectations for the Procedure resource to record, search, and fetch procedure information associated with a patient. It specifies which core elements, extensions, vocabularies, and value sets SHALL be present and constrains how the elements are used. Providing the floor for standards development for specific use cases promotes interoperability and adoption.

Example Usage Scenarios:

The following are example usage scenarios for this profile:

- Query for procedures performed on a Patient
- Record or update a procedure performed on a Patient

### Mandatory and Must Support Data Elements

The following data elements must always be present (Mandatory definition) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.

Each Procedure Must Have:

1. a status
2. a code that identifies the type of procedure performed on the patient*
3. a patient
4. when the procedure was performed*

Each Procedure Must Support:

1. the encounter associated with the procedure

Additional USCDI Requirements:

This Additional USCDI Requirements element is not Mandatory or Must Support but is required for ASTP Health IT certification testing and is included in the formal definition of the profile and the Procedure examples.

1. who was involved in the procedure*
2. a reason or indication for referral or consultation*

*see guidance below

Profile Specific Implementation Guidance:

- *The `Procedure.performed` is mandatory if `Procedure.status` is "completed" or "in-progress".
- *The `Procedure.code` has an additional binding of "current" and a base "preferred" binding.
  - For the conformance rules on the current binding for coded data, review this section in the General Requirements page.
  - Procedure codes can be taken from SNOMED-CT, CPT, HCPCS II, ICD-10-PCS, CDT, or LOINC.
    - Only LOINC concepts that reflect actual procedures SHOULD be used
- A procedure including an implantable device SHOULD use `Procedure.focalDevice` referencing the US Core Implantable Device Profile.

- See the Screening and Assessments guidance page for more information when exchanging Social Determinants of Health (SDOH) Procedures

- *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`. When the Procedure does not have an associated ServiceRequest, it is communicated through the US Core Procedure Profile's `Procedure.reasonCode` or `Procedure.reasonReference`. Depending on the procedure being documented, a Server will select the appropriate Profile to use.
  - Although both `Procedure.reasonCode` and `Procedure.reasonReference` are marked as Additional USCDI Requirements, the certifying Server system is not required to support both, but SHALL support at least one of these elements. The certifying Client application SHALL support both elements.
    - when using `Procedure.reasonReference`:
      - Servers SHALL support at least one target resource in `Procedure.reasonReference`. Clients SHALL support all target resources in `Procedure.reasonReference`.
      - The referenced resources SHOULD be a US Core Profile as documented in Referencing US Core Profiles.

- *The profile elements `Procedure.asserter and Procedure.performer.actor` communicate the individual level provenance author data corresponding to the U.S. Core Data for Interoperability (USCDI) Provenance Author Data Elements.

Usages:

- Refer to this Profile: US Core Encounter Profile
- Examples for this Profile: Procedure/defib-implant and Procedure/rehab
- CapabilityStatements using this Profile: US Core Client CapabilityStatement and US Core Server CapabilityStatement

### Notes:

Quick Start

Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile's information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

- See the Scopes Format section for a description of the SMART scopes syntax.
- See the Search Syntax section for a description of the US Core search syntax.
- See the General Requirements section for additional rules and expectations when a Server requires status parameters.
- See the General Guidance section for additional guidance on searching for multiple patients.

#### US Core Scopes

Servers providing access to procedure data SHALL support these US Core SMART Scopes:

- resource level scopes: `<patient|user|system>/Procedure.rs`

#### Mandatory Search Parameters:

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

1. SHALL support searching for all procedures for a patient using the `patient` search parameter:

   `GET [base]/Procedure?patient={Type/}[id]`

   Example:

   1. GET [base]/Procedure?patient=1291938

   Implementation Notes: Fetches a bundle of all Procedure resources for the specified patient (how to search by reference)

2. SHALL support searching using the combination of the `patient` and `date` search parameters:

   - including support for these `date` comparators: `gt,lt,ge,le`
   - including optional support for AND search on `date` (e.g.`date=[date]&date=[date]]&...`)

   `GET [base]/Procedure?patient={Type/}[id]&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}`

   Example:

   1. GET [base]/Procedure?patient=1137192&date=ge2019-01-14

   Implementation Notes: Fetches a bundle of all Procedure resources for the specified patient and date (how to search by reference and how to search by token)

#### Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

1. SHOULD support searching using the combination of the `patient` and `status` search parameters:
   - including support for OR search on `status` (e.g.`status={system|}[code],{system|}[code],...`)

   `GET [base]/Procedure?patient={Type/}[id]&status={system|}[code]{,{system|}[code],...}`

   Example:

   1. GET [base]/Procedure?patient=1137192&status=completed

   Implementation Notes: Fetches a bundle of all Procedure resources for the specified patient and status (how to search by reference and how to search by token)

2. SHOULD support searching using the combination of the `patient` and `code` and `date` search parameters:
   - including optional support for OR search on `code` (e.g.`code={system|}[code],{system|}[code],...`)
   - including support for these `date` comparators: `gt,lt,ge,le`
   - including optional support for AND search on `date` (e.g.`date=[date]&date=[date]]&...`)

   `GET [base]/Procedure?patient={Type/}[id]&code={system|}[code]{,{system|}[code],...}&date={gt|lt|ge|le}[date]{&date={gt|lt|ge|le}[date]&...}`

   Example:

   1. GET [base]/Procedure?patient=1137192&date=ge2019-01-14T00:00:00Z&code=http://snomed.info/sct|35637008

   Implementation Notes: Fetches a bundle of all Procedure resources for the specified patient and date and procedure code(s). SHOULD support search by multiple codes. (how to search by reference and how to search by token and how to search by date)
