For hospital finance and compliance teams
Running price transparency at a hospital like this one?
The data on this page comes from the files hospitals and payers publish. We help hospitals publish theirs correctly, and take a fresh look at their chargemaster.
Compliance MRF
Publish a CMS-compliant machine-readable file
We turn your chargemaster and payer contracts into the CMS template file, then keep it current as rates change.
Get your chargemaster right for billing and payer contracts
Your chargemaster sets the gross charge on every claim, and many payer contracts base payment on it through percent-of-charge, lesser-of and stop-loss terms. We audit it line by line and show how your charges and negotiated rates compare with peer hospitals before your next negotiation.
