Historical Provider Specific Data for Public Use File in CSV Format

CMS is developing a new Provider Data Service to modernize public access to the Provider Specific File. To start, the service allows users to export historic inpatient PSF data in a spreadsheet format (CSV). This beta version allows users to download historical data by entering a URL in their browser. In the future, a graphical user interface (GUI) will be developed to enable more user friendly filtering.

To learn how to download historical data using a URL, follow the directions in the the user guide below:

What is the Provider Specific File?

The Medicare Administrative Contractor maintains the Provider Specific File (PSF).  The file contains information about the facts specific to the provider that affects computations for the Prospective Payment System. 


CMS has begun an effort to modernize the Provider Specific File. We need your feedback to ensure we are not changing or breaking something you use or care about. We also want to improve your experience! No ask is too small.

Please email ModernizingMedicare@cms.hhs.gov with the subject line "Provider Specific File Feedback" with your comments or suggestions. The team will only respond to messages related to the Provider Specific File.

We look forward to hearing from you!
