## 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 hcpcs-level-ii-code-lookup-1ea134d8
```

Example prompt: What is HCPCS code E0601 — give me the full description, what category it falls under (like DME or drugs), and whether it's still active or has been terminated.

## When to prefer this

Use this endpoint when you need authoritative CMS HCPCS Level II code details — including descriptions, category classification, and lifecycle dates — for medical billing, claims processing, or compliance workflows. Prefer this over generic medical code databases when you need public-domain CMS data specifically for non-CPT codes like DME, drugs, ambulance, orthotics, or supplies.

## Known failure modes

- Invalid or malformed code returns 404 or empty result
- CPT codes (AMA-licensed) are not covered and will return no data
- Terminated or obsolete codes may still return data but with a terminated date and obsolete flag set
- Network timeout for slow responses
- Code not yet in the CMS database if recently added
