Tune into the ninth episode of our podcast series, Get the Facts on COVID-19. In episode 9, Avalere experts from the Health Plans and Providers practice and the Center for Healthcare Transformation discuss the near- and long-term impacts of COVID-19 on value-based contracting and Alternative Payment Models (APMs). The conversation focuses on Medicare programs, such as specialty Accountable Care Organizations (ACOs) and bundled payment models, and newer Center for Medicare and Medicaid Innovation (CMMI) programs.

Avalere’s analysis found that hospice patients diagnosed with cardiovascular and dementia conditions represent the largest proportion of “live discharges” compared to patients with other conditions.

New analysis from Avalere finds that more accountable care organizations (ACOs) participating in the Medicare Shared Savings Program (MSSP) have assumed downside risk as the program matures, with the greatest growth over the past 3 years.

The Centers for Medicare & Medicaid Services (CMS) announced that 121 new Medicare Accountable Care Organizations (ACOs) have joined the Medicare Shared Savings Program (MSSP) and Next Generation (Next Gen) ACO models.
