Section 425.222 - Eligibility to re-enter the program for agreement periods beginning before July 1, 2019(a) For purposes of determining the eligibility of a re-entering ACO to enter an agreement period beginning before July 1, 2019, the ACO may participate in the Shared Savings Program again only after the date on which the term of its original participation agreement would have expired if the ACO had not been terminated.(b) For purposes of determining the eligibility of a re-entering ACO to enter an agreement period beginning before July 1, 2019, an ACO whose participation agreement was previously terminated must demonstrate in its application that it has corrected the deficiencies that caused it to be terminated from the Shared Savings Program and has processes in place to ensure that it remains in compliance with the terms of the new participation agreement.(c) For purposes of determining the eligibility of a re-entering ACO to enter an agreement period beginning before July 1, 2019, an ACO whose participation agreement was previously terminated or expired without having been renewed may re-enter the program for a subsequent agreement period. (1) If the termination occurred less than half way through the agreement period, an ACO that was previously under a one-sided model may reenter the program under the one-sided model or a two-sided model. If the ACO reenters the program under the one-sided model, the ACO will be considered to be in the same agreement period under the one-sided model as it was at the time of termination.(2) If the termination occurred more than half way through the agreement period, an ACO that was previously in its first agreement period under the one-sided model may reenter the program under the one-sided model or a two-sided model. If the ACO reenters the program under the one-sided model, the ACO will be considered to be in its second agreement period under the one-sided model. An ACO that was previously in its second agreement period under the one-sided model must reenter the program under a two-sided model.(3) Regardless of the date of termination, an ACO that was previously under a two-sided model may only reapply for participation in a two-sided model. 76 FR 67973 , Nov. 2, 2011, as amended at 80 FR 32839 , June 9, 2015; 83 FR 68065 , Dec. 31, 2018
