Hospital price transparency compliance,
done right.

We turn your payment data into a machine-readable file that passes CMS's official validator — and we manage the CEO attestation. Built for critical-access and rural hospitals.

The 2026 rule is here, and enforcement has started

CMS now requires every hospital to publish what it is actually paid for its services — a typical (median) price, plus a low and high range — calculated from your own insurance payment records (your 835 remittance data). It must be in CMS's exact file format, with your CEO's name attesting that it is accurate. Enforcement began April 1, 2026, and hundreds of hospitals are already under warning notices or corrective-action plans.

Proof, not promises

A published file is not the same as a passing one. We have run the public files of 500+ hospitals already under CMS enforcement through the government's own validator — and most still fail. We make yours pass, and we prove it against that same validator.

What AttestWell does

From your raw payment data to a filed, defensible, validator-passing file — and we keep it current.

1

Send us your data

You securely send your 835 remittance file under a Business Associate Agreement. No IT project on your end.

2

We do the math

We compute the median, 10th- and 90th-percentile allowed amounts CMS requires, exactly to the 2026 rule.

3

You get a passing file

A CMS v3.0 file checked against CMS's own validator, plus a simple sign-off workflow for your CEO's attestation.

Who it's for

For the CFO

Remove six-figure penalty exposure without adding work to your revenue-cycle team. We handle the computation and the file; you stay compliant.

For the CEO

Your name goes on the attestation. We make sure the numbers behind it are correct — so you can sign with confidence.

Built for rural hospitals — and rural budgets

No IT project: you send us a file, we do the rest. Everything runs HIPAA-compliant, under a Business Associate Agreement.

Our critical-access pricing is built to fit within the SHIP grant — federal funding that many rural hospitals can already use for price-transparency software. For many hospitals, that means most of the cost is grant-covered.
