## 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 cms-medicare-inpatient-drg-hospital-averages-8afeccc0
```

Example prompt: Pull CMS Medicare inpatient hospital averages for MS-DRG code 871 in Florida — show me up to 10 hospitals with their average submitted charges and Medicare payments.

## When to prefer this

Use this endpoint when you need hospital-level Medicare inpatient billing and payment averages for a specific MS-DRG code — ideal for healthcare cost research, price transparency analysis, hospital benchmarking, or policy work. Prefer this over IPPS national rate tables when you need actual per-hospital averages rather than CMS-set rates, and over general hospital lookup endpoints when you need DRG-specific financial data.

## Known failure modes

- Invalid or non-existent DRG code returns empty results or an error
- Invalid state code (not a 2-letter US abbreviation) may return an error or no results
- DRG codes with very few hospital submissions may return fewer rows than requested
- max parameter outside 1–20 range may be clamped or rejected
- Network or upstream CMS data availability issues causing a 500 error

## How this service works

CMS Medicare inpatient hospital averages per MS-DRG (data.cms.gov, fee-for-service Part A): hospital name, state, DRG code and description, discharges, average submitted charge, average total payment and average Medicare payment. Hospital-level averages, not the IPPS national rate table. Filter by 3-digit DRG code and optional state; up to 20 rows.

## Output

Returns up to 20 rows of hospital-level data including: hospital name, state, MS-DRG code and description, number of discharges, average submitted charge, average total payment, and average Medicare payment — sourced from CMS fee-for-service Part A data on data.cms.gov.
