CMS-Required Hospital Charge Data

Mass General Brigham provides information about the rates negotiated with insurance companies for all services and items offered by our hospitals.

How can I view your hospital charge data?

As required by the federal government (Centers for Medicare and Medicaid Services, or “CMS”), we publish information (comprehensive machine-readable files) about the rates negotiated with insurance companies for all services and items offered by our hospitals. These files are listed below and available for download. 

Please note: Because of the size of the files, you may need special computer software/speed to open the files. 

This price information contained in these large files is NOT an estimate of the costs that you are responsible for paying. These files are not intended for patients and do not reflect your out-of-pocket costs. If you are a patient, you can request a cost estimate by contacting Patient Billing Solutions or using our online tool to view a cost estimate of common health care services ("shoppable items").
