What Can It Do?

Autocode clinical text into ICD-11 codes

Paste free-text clinical descriptions and get the right code back. No more manual lookups.

{"action": "autocode", "query": "acute bronchitis with fever"}
→ CA20 Acute bronchitis (92.3% confidence)

{"action": "autocode", "query": "patient presents with chest pain and shortness of breath"}
→ MD81 Chest pain (87.1% confidence)

Look up any ICD-10 or ICD-11 code instantly

Get definitions, coding notes, inclusions, exclusions — everything a coder needs.

{"action": "lookup", "code": "BA00"}
→ BA00: Lobar pneumonia — full definition, coding notes, inclusions/exclusions

{"action": "lookup", "code": "J18.9", "version": "10"}
→ J18.9: Pneumonia, unspecified (ICD-10)

Search by keyword

Don't know the code? Describe it and get ranked results.

{"action": "search", "query": "type 2 diabetes with kidney complications"}

{"action": "browse"}
→ All 28 ICD-11 chapters (or 21 ICD-10 chapters)

{"action": "browse", "code": "BA00"}
→ Parent context + sub-categories with ▸ expansion markers

Trace a code's full lineage

Walk from any leaf code all the way up to its chapter root.

{"action": "ancestors", "code": "BA01.0"}
→ BA01.0 → BA01 → BA0Y-BA2Z → Diseases of the respiratory system → Chapter 12

Validate codes instantly

Quick yes/no — is this a real code? Is it a leaf or a category?

{"action": "validate", "code": "BA00"}
→ Valid ICD-11 code, category level, has sub-codes
