Given a code/system, or a Coding, get additional details about the concept, including definition, status, designations, and properties. One of the products of this operation is a full decomposition of a code from a structure terminology
In Aidbox this is essentially the same as search Concept by system and code
GET [base]/fhir/CodeSystem/$lookup?system=http://loinc.org&code=1963-8
equals to
GET [base]/Concept?system=http://loinc.org&code=1963-8
The only difference is response format.
With Concept Search you can do even more, than just getting one concept. For example search and filter by any concept elements.
POST [base]/CodeSystem/$lookup
