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.

DecimalAI ran this skill against gemini-3.5-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 23 cases were attempted. The headline lift of +52 percentage points is the difference between those two pass rates over the 23 comparable cases.
The per-case answers from this run were removed by the retention sweep, so the case table below shows the verdicts without the text either arm produced. The counts above were recorded at the time and are unaffected. Answers are now kept for 180 days.
