## 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-4442bc9e
```

Example prompt: What does HCPCS code K0001 mean? I need the official description and any details about that billing code for medical equipment.

## When to prefer this

Use this endpoint when you need to resolve, describe, or search HCPCS Level II codes — specifically for medical supplies, durable medical equipment (DME), orthotics, prosthetics, and non-physician services. Prefer this over ICD-10 endpoints for billing/supply codes, and over drug-name endpoints for equipment and service codes.

## Known failure modes

- Invalid or non-existent HCPCS code returns no match or empty results
- Search query with no matching descriptions returns empty results list
- Missing required 'q' query parameter returns an error
- Limit out of range (>25 or <1) may return an error or be clamped
- Service degraded flag may be set indicating partial data availability

## How this service works

HCPCS Level II billing codes (supplies, equipment, services): look up a code or search by description.

## Output

Returns a structured result including the HCPCS code, its official description, a summary, source URL, verdict, disclaimer, and metadata such as the date the data is current as of. For search queries, returns multiple matching codes up to the specified limit (default 10, max 25).
