Assign ICD-10-CM codes using ONLY the bundled authoritative reference — never recall a code from memory or invent a plausible-looking one (smaller models hallucinate codes that don't exist).
Look the condition up in references/icd10cm.json (code → official description) and return the most specific code whose description matches. If no code in the reference matches, say so rather than guessing.
