CodeSystem subsumption testing (deprecated)

Overview

Test the subsumption relationship between code/Coding A and code/Coding B given the semantics of subsumption in the underlying code system. For more details, see the official documentation FHIR CodeSystem $subsumes

Api

URL: [base]/CodeSystem/$subsumes

URL: [base]/CodeSystem/[id]/$subsumes

Parameters

Parameter	Type	Status	Example
codeA	code	`supported`	code
codeB	code	`supported`	code
system	uri	`supported`	system
codingA	Coding	`supported`	coding
codingB	Coding	`supported`	coding
version	string	`not supported`	-

Examples

We will use goal-status CodeSystem which consists of :

Code	Parent codes
accepted	`-`
achieved	`["accepted"]`
ahead-of-target	`["accepted", "in-progress"]`
behind-target	`["accepted", "in-progress"]`
cancelled	`-`
entered-in-error	`-`
in-progress	`["accepted"]`
on-hold	`["accepted"]`
on-target	`["accepted", "in-progress"]`
planned	`["accepted"]`
proposed	`-`
rejected	`-`
sustaining	`["accepted", "in-progress"]`

Result of subsumption

The subsumption relationship between code/Coding "A" and code/Coding "B". There are 4 possible codes to be returned: equivalent, subsumes, subsumed-by, and not-subsumed. If the server is unable to determine the relationship between the codes/Codings, then it returns an error.

Requests examples

With Coding

You will receive same subsumption results

POST [base]/CodeSystem/$subsumes
content-type: text/yaml

resourceType: Parameters
parameter:
- name: system
  valueUri: 'http://hl7.org/fhir/goal-status'
- name: codingA
  valueCoding: {code: accepted}
- name: codingB
  valueCoding: {code: achieved}

You can also combine code and Coding

POST [base]/CodeSystem/$subsumes
content-type: text/yaml

resourceType: Parameters
parameter:
- name: system
  valueUri: 'http://hl7.org/fhir/goal-status'
- name: codingA
  valueCoding: {code: accepted}
- name: codeB
  valueCode: achieved
