Under 45 CFR Part 180, every US hospital must publish a machine-readable file of its standard charges, including gross charges, discounted cash prices and payer-specific negotiated rates, in the CMS template format. PayerPrice can help hospitals publish and maintain these files.
A chargemaster (charge description master, or CDM) is a hospital's master list of billable items, with codes, descriptions and gross charges. A chargemaster review looks at those lines for accuracy and pricing. PayerPrice can help hospitals review their chargemaster; contact us to discuss your needs.
For hospital finance and compliance teams
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.
We turn your chargemaster and payer contracts into the CMS template file, then keep it current as rates change.
