How this service works
What an ICD-10-CM diagnosis code means: official description, chapter, and whether it is a complete code or a category header.
Output
Returns the official ICD-10-CM description, the chapter (number, title, and range), the code set (e.g. ICD-10-CM), a verdict indicating whether the code is billable or a category header, the data as-of date, a source URL, and a disclaimer. May also include child codes if the code is a category, and degraded-mode flags if data is partial.
Example use cases
Decode a diagnosis code from a medical record
“I have this diagnosis code on a patient chart: J45.50 — what does it mean, what chapter is it in, and is it a complete billable code?”
Verify billing code before submitting a claim
“Before we submit this insurance claim, can you check whether ICD-10 code M79.3 is a valid billable code or just a category header?”
Explain a diagnosis code to a patient
“My doctor listed F41.1 on my paperwork — can you tell me the official description of that ICD-10-CM code and what medical chapter it falls under?”

For finding codes by keyword or symptom, prefer the ICD-10-CM search endpoint on the same service. This endpoint is ideal for decoding codes found in medical records, EHR exports, or insurance claims.
