In late August 2025, CMS released Performance Year (PY) 2024 data for the Medicare Shared Savings Program (MSSP). MSSP incentivizes participants to provide coordinated, high-quality care while lowering costs by sharing a portion of savings achieved for Medicare with participants. This marked the twelfth year of the program and the eighth consecutive year MSSP has achieved savings for Medicare (based on comparisons to the benchmark). The PY 2024 MSSP results are largely positive and support the continued success of the program. Accountable care organizations’ (ACO) participation increased compared to last year, and shared savings reached the highest level in the history of the program. As always, benchmarks represent a spending target and should not be interpreted as a counterfactual, so assessment of performance based on comparisons against benchmarks, including quality, should be interpreted with caution. Our results are unadjusted, savings are calculated from benchmarks set in advance based on a blend of historical ACO and regional spending, and rates of uncontrollable circumstance adjustments are increasing (often a function of natural disasters and other emergencies).
