CMMI Model Data Sharing (CMDS) Model Participation Data Initiative

The CMS Innovation Center is committed to making model data more easily available to stakeholders to advance transparency on model performance and to support external research and learning. In line with this commitment, the CMS Innovation Center is releasing model participant data for use in data analysis research projects.

These data files may be used as ‘finder files’ in combination with other requested CCW files to isolate results to include (or not include as desired) entities, providers and or beneficiaries participating in specific models.

Each model has a set of up to three (3) files, one per participant type:

  1. Entity file
  2. Provider file
  3. Beneficiary file

Data for each model will be updated the first month of each calendar quarter.

The quarterly file updates are “full replacement files” and contain data from the launch of each model to the current quarter. Note: Participating entities, providers and beneficiaries may frequently change due to time lags in updates by model participants to their provider lists and/or to changes in beneficiary attribution. As such, these files should not be considered fully complete or final until approximately 6-12 months after a model has ended.

CMS is releasing data files for the following models:

          Note: The GPDC model is transitioning to the ACO REACH model as of January 1, 2023.

  • Oncology Care Model (OCM) - In this model, physician practices enter into payment arrangements that include financial and performance accountability for episodes of care surrounding chemotherapy administration to cancer patients.
  • Bundled Payments for Care Improvement Advanced (BPCI Advanced) Model - This model supports healthcare providers who invest in practice innovation and care redesign to better coordinate care and reduce expenditures, while improving the quality of care.
  • Comprehensive Primary Care Plus (CPC+) Model - This national advanced primary care medical home model aims to strengthen primary care through regionally-based multi-payer payment reform and care delivery transformation.
  • Kidney Care Choices (KCC) Model - This model helps health care providers reduce the cost and improve the quality of care for patients with late-stage chronic kidney disease and ESRD and aims to delay the need for dialysis and encourage kidney transplantation.
  • Primary Care First (PCF) Model - This voluntary alternative five-year payment model rewards value and quality by using an innovative payment structure to support the delivery of advanced primary care.

The group of models for which CMDS participation files are available will expand over time to include additional models.

The model IDs for the 6 models in the CMDS file set is depicted in the table below.
