About ChargemasterDB

ChargemasterDB helps people compare hospital chargemaster prices published under the federal hospital price transparency rule. The site brings those files into one searchable database so patients, researchers, and journalists can quickly see how prices vary across hospitals.

What the site does

Each hospital page shows price data tied to a hospital and its latest published chargemaster records. Code pages aggregate that data so you can compare a procedure across hospitals, review national and state-level pricing distributions, and identify unusually high or low charges.

The search tools let you look up billing codes directly, search by description, and jump from a hospital to the procedure prices published for that facility.

How to use it

  • Search for a CPT or HCPCS code to compare hospitals side by side.
  • Open a hospital page to see prices published by that facility.
  • Use the data as a starting point for billing review, price negotiation, or market research.

Data source and limitations

The database is built from hospital pricing files published to comply with CMS hospital price transparency requirements. Hospitals do not all publish data in the same format, and chargemaster prices are not the same as the amount a patient or insurer will actually pay. They are still useful for understanding relative pricing, spotting outliers, and asking better questions before care.

If you are comparing costs for a real medical bill, use these figures alongside an itemized bill, your insurance benefits, and written estimates from the hospital.
