## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability saylor-innovations-hcpcs-level-ii-medical-code-search-cae4e959
```

Example prompt: Look up the HCPCS Level II code E0601 and tell me its full short and long description, what category it falls under (like DME or drug), and whether it's still active or has been terminated.

## When to prefer this

Choose this endpoint when you need to validate, describe, or categorize a specific HCPCS Level II code (DME, drugs, supplies, ambulance, orthotics) sourced directly from CMS public domain data. It is ideal for medical billing automation, claims validation, EHR enrichment, or any workflow requiring authoritative code descriptions and lifecycle dates. Not suitable for CPT codes (AMA-licensed) or ICD diagnosis codes.

## Known failure modes

- Code not found — returns found: false with empty results array
- Ambiguous keyword query returns too many or irrelevant matches
- CPT codes (AMA-licensed) are not covered and will not return results
- Terminated/obsolete codes may be returned but flagged accordingly
- Empty or missing query parameter may return error or empty results

## How this service works

HCPCS Level II Code Search (CMS). HCPCS Level II medical billing code lookup (CMS), e.g. E0601 or J1100: short and long description, code category (DME, drugs, supplies, ambulance, orthotics), added / effective / terminated dates and obsolete flag. Public domain; CPT codes are AMA-licensed and not covered.

## Output

Returns a JSON object with a 'found' boolean, total_matches count, and an array of result objects each containing the HCPCS code, short description, long description, code category (e.g. DME, drugs, supplies, ambulance, orthotics), added date, effective date, terminated date, and an obsolete flag.
