Medicare Program; Medicare Shared Savings Program: Extreme and Uncontrollable Circumstances Policies for Performance Year 2017. Interim final rule with comment period

This interim final rule with comment period establishes policies for assessing the financial and quality performance of Medicare Shared Savings Program (Shared Savings Program) Accountable Care Organizations (ACOs) affected by extreme and uncontrollable circumstances during performance year 2017, including the applicable quality reporting period for the performance year. Under the Shared Savings Program, providers of services and suppliers that participate in ACOs continue to receive traditional Medicare fee-for-service (FFS) payments under Parts A and B, but the ACO may be eligible to receive a shared savings payment if it meets specified quality and savings requirements. ACOs in performance-based risk agreements may also share in losses. This interim final rule with comment period establishes extreme and uncontrollable circumstances policies for the Shared Savings Program that will apply to ACOs subject to extreme and uncontrollable events, such as Hurricanes Harvey, Irma, and Maria, and the California wildfires, effective for performance year 2017, including the applicable quality data reporting period for the performance year.
