What CMS enforcement actually looks like
Since January 1, 2026, every hospital's machine-readable file must follow CMS's v3.0 format — including the median, 10th- and 90th-percentile allowed amounts calculated from your own remittance data, and a named attestation of accuracy (45 CFR § 180.50). Enforcement of the new requirements began April 1, 2026.
Under 45 CFR § 180.90, civil monetary penalties for hospitals of 30 beds or fewer run about $323 per day — roughly $118,000 a year. Larger hospitals pay per bed, per day — up to roughly $2,000,000 a year. CMS adjusts these amounts annually for inflation, and it publishes its enforcement actions publicly — hundreds of hospitals are already under warning notices or corrective-action plans.
Every hospital's attestation is signed by a senior official — usually the CEO. Your name goes on it.

We run CMS's official validator
The same open-source tool CMS publishes — not our interpretation of the rule.

Every error, what it means in plain English, and what fixing it takes. Yours to keep either way.
Built for the people who sign
For the CFO
For a critical-access hospital, non-compliance is up to ~$118,000 a year of penalty exposure — against a fix priced to fit inside the Small Rural Hospital Improvement Program (SHIP) grant many rural hospitals already receive. No new FTE, no IT project, no system-sized platform contract.

Before you sign this year's attestation, know what CMS's validator sees on your website today. We make sure the numbers under your signature are right.
Know what you're attesting to →For your HIM / IT lead: nothing to install, no EHR access, no network access. It works with whatever produced your current file — Epic, Cerner, a consultant, or a spreadsheet.

Pricing
File check. We run your public file through CMS's validator and send you the full report. No login, no card, and the report is yours.
Critical-access tier. Your file rebuilt from your 835 remittance data, validated against CMS's own tool, kept current, with an attestation-ready sign-off packet. One flat annual price, fixed at kickoff — where you land in the range depends on bed count and how many payer plans your file covers. Priced to fit within the SHIP grant. No implementation fee.
Small rural PPS tier. Same service, sized for larger rural hospitals.
For scale: penalty exposure for even the smallest hospital runs ~$118,000 a year — and price-transparency software is an allowable use of SHIP grant funds.
Security & data
The file we check is the machine-readable file your hospital already publishes to the public internet under 45 CFR § 180. For the free check we never access PHI, your EHR, or your network — and no BAA is required. When we later rebuild your file from 835 remittance data, that work runs under a signed Business Associate Agreement. This site is served over HTTPS and loads nothing from third parties. The only thing you submit here is your email address, and we use it for exactly one thing: sending your report.
Common questions
What do you do with our file?
We validate it, write your report, and that's it. It's already public data; we don't sell, share, or republish it. Your email address is used only to send the report and one follow-up.
Does passing the validator mean we're fully compliant?
It means your file meets the v3.0 format and completeness checks CMS's tool enforces — the layer where most files fail today. Full compliance also covers the accuracy of the underlying data and your consumer display requirements, which is exactly what our paid service takes on.
Do we need IT involved?
No. The free check uses your public website. Even the paid service is a file transfer — no installation, no EHR integration.
What does the free check cost later?
Nothing, ever. It's how we show our work. If your file passes, we'll tell you that too.
We already have a vendor — why check?
A posted file isn't the same as a passing one. As of mid-2026, we've run dozens of hospitals' public files through the validator — including many from hospitals on CMS's published enforcement list — and most fail at least one current check. If your vendor's file passes, you've lost nothing and gained proof.
You're new — will you be around?
Fair question. The check runs on CMS's own open-source validator, not our black box — and the report is yours to keep either way. You can verify everything we tell you against CMS's published tooling.
Is this legal advice?
No. AttestWell provides compliance tooling and reporting, not legal advice.
