This CodeSystem is declared as a stub (content = #not-present). The authoritative content is maintained by the World Health Organization. In Bangladesh, runtime code validation and lookup are delegated to the national OCL terminology server at https://tr.ocl.dghs.gov.bd.

Supported operations (use `system=` parameter, not `url=`):

- $validate-code: https://tr.ocl.dghs.gov.bd/api/fhir/CodeSystem/$validate-code?system=http://id.who.int/icd/release/11/mms&code={code}
- $lookup: https://tr.ocl.dghs.gov.bd/api/fhir/CodeSystem/$lookup?system=http://id.who.int/icd/release/11/mms&code={code}

$expand is not supported — known OCL limitation. Expansion must not be attempted at build time or by IG Publisher.

Preferred code form: short stem codes (e.g. 1A00, NC72.Z). Linearization URIs are not used as code identifiers in this IG.

Version 2025-01 is imported into OCL with 36,941 concepts across the following concept classes: Diagnosis, Finding, Substance, Organism, Device, Anatomy, Misc.
