    • Medicare Geographic Variation - by Hospital Referral Region

    Metadata Updated: September 8, 2025

    The Medicare Geographic Variation by Hospital Referral Region dataset provides information for researchers and policymakers to evaluate the geographic differences in the use and quality of health care services for the Original Medicare population. The dataset includes demographic, spending, use, and quality indicators at the hospital referral region (HRR) level.

    Please note that CMS has decided to discontinue updates to the Fee-for-Service (FFS) Geographic Variation Public Use File by Hospital Referral Region, so the dataset is retired. Data in the FFS Geographic Variation Public Use File by Hospital Referral Region has been divided into two files: 2007-2013 data and 2014-2021 data. This was done to account for changes to the Geographic Variation methodology beginning with data year 2014. The 2007-2013 data is located under data year 2013, and the 2014-2021 data is located under data year 2021.
