The Centers for Medicare & Medicaid Services (CMS) has expanded the archive for Doctors and Clinicians (DAC) in the Provider Data Catalog (PDC) on Care Compare. This expansion allows users to access historic Merit-based Incentive Payment System (MIPS) program performance data that were previously publicly reported in the PDC since the program’s inception in 2017. This update benefits doctors, clinicians, researchers, and other interested parties who want access to all historic MIPS performance data previously publicly reported. Users can access the archive files.

CMS strongly cautions users against using the historical data to draw year-to-year performance comparisons. There are several aspects of the MIPS program and public reporting standards that make it inappropriate to make such comparisons – especially of measure-level performance over time. Additional details and information are available in the MIPS Data Archive on Care Compare: Doctors and Clinicians fact sheet and disclaimer.
