On March 31, 2011, CMS released the proposed rule implementing the Medicare Shared Savings program and establishing the requirements for Accountable Care Organizations (ACOs) that wish to participate in this program. The following is a list of some of the highlights from this Proposed Rule.
1. The proposed rule contemplates two models: a “one-sided” model in which providers do not share risk and a “two-sided” model in which providers share in risk and realize greater return on the shared savings.
2. ACOs must commit to participate in the shared savings program for three years. Providers who select the “one-sided” option will need to agree to share risk in their final year of participation. If an ACO wants to terminate early, they will need to give a 60 day notice to CMS, as well as a notice to beneficiaries, and will forfeit a portion of previously earned shared savings that was withheld by CMS.
