description	Carries a postcoordinated ICD-11 cluster expression as a single string on a Coding element where the stem code alone is insufficient to fully represent the clinical concept. A cluster expression combines a stem code with one or more satellite codes using the & operator (combination) or / operator (specificity). Example: NC72.Z&XK8G&XJ7ZH&XJ7YM - NC72.Z — stem: Fracture of femur, unspecified - XK8G — satellite: laterality - XJ7ZH — satellite: fracture subtype - XJ7YM — satellite: fracture open or closed Usage rules: - SHALL only be present when the expression contains at least one satellite code joined by & or / operators. - Single stem codes SHALL be represented in Coding.code only and validated via OCL $validate-code. The cluster validator at https://icd11.dghs.gov.bd/cluster/validate explicitly rejects stem-only expressions. - The stem code in Coding.code SHALL match the leading stem code in this expression string. - Satellite codes in the cluster expression are exempt from the Diagnosis/Finding class restriction that applies to stem codes in Condition.code. - Cluster expressions SHALL be validated against the Bangladesh ICD-11 Cluster Validator at https://icd11.dghs.gov.bd/cluster/validate prior to submission to the HIE. Cluster validator endpoint: POST https://icd11.dghs.gov.bd/cluster/validate Body: { "expression": "NC72.Z&XK8G&XJ7ZH&XJ7YM" } This extension is not MustSupport and is not mandatory. It is present only when postcoordination is clinically required. Cluster expressions are typically sourced from the WHO Electronic Coding Tool (ECT) at the point of care.
