| *Official URL*:https://fhir.dghs.gov.bd/core/NamingSystem/icd11-mms-bd | *Version*:0.4.0 | |
| * Standards status: *[Informative](http://hl7.org/fhir/R4/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 1 | *Computable Name*:ICD11MMSBangladesh |

 
Declares the ICD-11 Mortality and Morbidity Statistics (MMS) coding system as a known and supported terminology within the Bangladesh national health information infrastructure. 
Canonical system URI: http://id.who.int/icd/release/11/mms Canonical authority: World Health Organization (WHO) 
Preferred code form: short stem codes (e.g. 1A00, NC72.Z). Linearization URIs are not used as code identifiers in this IG. 
National terminology resolver (OCL): https://tr.ocl.dghs.gov.bd 
Supported OCL 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. 
Version 2025-01 is active in the national OCL instance with 36,941 imported concepts. The OCL resolver is an internal national service; vendors do not interact with it directly. All vendor submissions are validated at the HIE boundary via the Bangladesh ICD-11 Cluster Validator at https://icd11.dghs.gov.bd/cluster/validate.
