Example prompt: Can you search for HCPCS Level II billing codes related to 'wound care' and show me the top 10 matching codes with their descriptions?

## When to prefer this

Use this endpoint when you need to search CMS HCPCS Level II codes by descriptive keyword — ideal for medical billing automation, claims coding assistance, or supply/drug code lookup. Note that CPT codes are AMA-licensed and not available here; for CPT lookups you need a different licensed source. Best suited for lightweight, keyword-driven code searches returning up to 20 results.

## Known failure modes

- Search term shorter than 2 or longer than 60 characters returns a validation error
- Max parameter outside 1–20 range may be rejected or clamped
- No results found for obscure or misspelled terms (returns empty codes array with total 0)
- NLM Clinical Tables upstream unavailability causes failure
- CPT codes (AMA-licensed) are explicitly excluded and will not appear in results

## How this service works

HCPCS Level II billing code search (CMS code set, via NLM Clinical Tables): code and short description for procedures, supplies and drugs, with total match count. CPT codes are AMA-licensed and not included. Up to 20 codes per call.

## Output

Returns a JSON object containing the search term used, an array of matching HCPCS Level II codes (each with a code string like 'J1817' and a short description), the total number of matches found in the dataset, the NLM source URL, and the timestamp of the lookup.
