lookup_icd10_cm
Look up ICD-10-CM diagnosis codes by code or keyword to find English and Traditional Chinese descriptions, category, and related OPDSTAR specialties.
Instructions
Look up ICD-10-CM diagnosis codes with English / Traditional Chinese descriptions, category, and the OPDSTAR specialties each code is keyed against. Use when the agent encounters an ICD-10 code in a note, claim, or rejection notice and needs the canonical name, or wants to free-text search by EN / 中文 keyword to find candidate codes. Typical follow-up: chain into get_procedures_for_icd({icd10, specialty}) to find the procedures commonly paired with the code, or check_icd_for_major_illness_eligibility({icd10}) to check 重大傷病 coverage. Scope note: Currently backed by OPDSTAR's specialty-keyed Taiwan-relevant subset (~3,000 codes covering the diagnoses doctors actually code on outpatient claims); the full CMS public-domain ICD-10-CM 2025 set (~70K codes) will be merged in a later release. Out of scope: SNOMED CT cross-mapping, international procedure codes (ICD-10-PCS), drug interactions. Reference only — clinical coding decisions require physician judgment. Curated by OPDSTAR (https://opdstar.com).
