NHI CQL Generator

• You have an NHI rule code and full rule text and need to produce a deployable CQL library and FHIR ValueSet in one step
• You are building or maintaining a Taiwan NHI clinical decision support system and need consistent, pattern-compliant artifacts
• You need to encode frequency limits, contraindications, specialist restrictions, or multi-subpopulation logic from 健保給付規則 into executable CQL
• You want to generate multiple related ValueSets (indication + contraindication) with correct OID-based naming and filter operators

• You need CQL for non-Taiwan health insurance systems (e.g., US Medicare, EU payers) — this skill's codesystems and patterns are NHI-specific
• Your rule text is incomplete or missing 適應症 and 點數 — the skill requires structured rule input to produce valid output
• You need a FHIR terminology server or ValueSet expansion service — this skill generates authoring artifacts, not expanded code lists

Produces .cql files with correct library declarations, FHIR 4.0.1 headers, valueset/codesystem declarations, and define logic (MeetsInclusionCriteria, InPopulation, Recommendation, etc.) following documented NHI GT patterns exactly.

Creates ValueSet files using OID-based IDs (2.16.840.1.113762.1.4.1287.[N]), selects the correct filter operator (descendent-of, is-a, =, or in) based on code granularity, and populates all required metadata including the 4-part purpose field.

Directly uses CDSConnectCommonsForFHIRv401 (C3F) functions — Confirmed, Verified, MostRecent, ObservationLookBack, QuantityValue, and more — without redundant redefinition, keeping generated CQL clean and maintainable.

Translates NHI frequency rules ("一年限申報三次", "限住院期間申報一次", "每人以申報一次為原則") into correct CQL using ProcedureLookBack time windows or Encounter-reference checks as appropriate.

Automatically distinguishes regulations that must become executable CQL (specialist restrictions, contraindications, procedure type checks) from those that belong only in Recommendation text (material fee add-ons, administrative requirements).

Every output includes FHIRHelpers.cql (v4.0.1) and CDSConnectCommonsForFHIRv401.cql (v2.1.0) copied from the skill assets directory, preventing the Could not load source for library runtime error.

Convert a single-indication NHI rule (e.g., 08111B for Von Willebrand disease screening at 800 points) into a CQL library and matching ICD-10-CM ValueSet with correct filter operators.

Generate CQL for rules like 17022B (FeNO monitoring) that require age range checks (6–12 years), annual frequency limits (≤3 times/year), and pediatric specialty encounter validation.

Handle rules with multiple 適應症 groups each carrying different frequency constraints — such as 12216C where HIV patients get annual testing and dialysis patients get quadrennial testing — using the subpopulation pattern.

Produce CQL that checks both positive indications and the absence of contraindications, generating separate ValueSets for each and branching the Recommendation string to explain denial reasons.
