Key Findings
  • Practices’ ability to work on CPC+ care delivery requirements was hindered by the COVID-19 pandemic, but a range of supports (such as care managers) and temporary changes in payment policies (such as Medicare fee-for-service payment for telehealth) helped practices continue to fund their COVID-19 work.
  • CPC+ practices cited care management fees as the most useful type of CPC+ payment support they received, used primarily to fund the salaries of care managers, behavioral health care providers, and other staff to improve care delivery.
  • The annual increase in the number of practice sites with on-site behavioral health specialists was valuable, particularly during the fourth year as the COVID-19 pandemic increased mental health care demand during a very challenging time to secure services.
  • CPC+ practices saw reductions in emergency department (ED) visits, acute hospitalizations, and acute hospitalization expenditures and improvement in some quality-of-care measures, though overall savings to Medicare were offset by increases in expenditures on other services.

The Comprehensive Primary Care Plus (CPC+) Model: Findings at a Glance provides a brief overview of the independent evaluation’s findings about the first four years of CPC+ for the 2,905 practices in regions that began CPC+ in 2017. A full report on the evaluation of CPC+’s four year is found in the Independent Evaluation of Comprehensive Primary Care Plus (CPC+): Fourth Annual Report, which describes (1) engagement in CPC+ by payer partners and health IT vendors and participation by practices; (2) the supports practices received; (3) how practices implemented CPC+ and changed the way they delivered health care; and (4) the impacts of CPC+ on cost, service use, limited claims-based quality-of-care outcomes, and patient experience for attributed Medicare fee-for-service beneficiaries.
