The Medicare Shared Savings Program (Shared Savings Program or MSSP) is a program developed by CMS in 2012 that enables providers and suppliers of health care such as physicians and hospitals to set up an accountable care organization (ACO). The Shared Savings Program is a novel Medicare payment model which shifts away from the focus on volume-based reimbursement metrics and toward improved patient outcomes and increased value (value-based care). Under the MSSP, the ACO is charged with serving an assigned FFS Medicare beneficiary population, with a focus on improving patient outcomes while reducing cost of care. The Shared Savings Program holds ACOs accountable to certain standards while providing patient care, including quality, cost, and patient experience. These metrics are tied to the ACO’s reimbursement for services provided.
