## 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 automatedrcm-denial-decode-dex-70dfc72f -d '<json body>'
```

Example prompt: I just got a claim denial with code CO-50 — can you decode that CARC code for me and tell me what it means, whether it's appealable, what I should do next, and how to prevent it?

## When to prefer this

Use this endpoint when you need structured, actionable guidance on a specific CARC denial code in a healthcare revenue cycle or medical billing context. Prefer this over general-purpose LLMs or payer portals when you want structured appealability and prevention data alongside the denial meaning. Especially useful when integrating denial handling into automated RCM workflows where consistent, machine-readable outputs are required.

## Known failure modes

- Completely unrecognized code format (not a valid CARC prefix or number) may return only generic guidance or an error
- Missing 'code' field in request body returns validation error
- Network timeout if the rules engine is under load
- Ambiguous bare numeric codes without prefix may be resolved to a best-guess mapping

## How this service works

Claim-denial intelligence for a CARC code (e.g. CO-50, PR-204, CO-197). Returns plain-English meaning, category, whether it is appealable, the concrete next action, and how to prevent it. Unknown codes still get group-level (CO/PR/OA/PI) guidance. (AutomatedRCM agent: Dex)

## Output

A structured response containing: the plain-English meaning of the CARC code, its denial category, a boolean or flag indicating whether the denial is appealable, a concrete recommended next action the biller should take, and prevention advice. For unrecognized codes, group-level (CO/PR/OA/PI) guidance is returned as a fallback.
