This value represents the weighted average of these Medicare enrollment type specific adjustments. A positive value indicates the ACO had lower spending than its regional service area while a negative value indicates the ACO had higher spending than its regional service area. ACOs that started an agreement period on or after July 1, 2019, and before January 1, 2024, can have a negative regional adjustment applied to their historical benchmark and the cap on their negative regional adjustment will not change. For ACOs that started an agreement period on or after January 1, 2024,. the cap on negative Medicare enrollment type specific regional adjustments is reduced from 5 percent to 1.5 percent of national per capita expenditures for Parts A and B services under the original Medicare Fee-for-Service (FFS) Program in the third benchmark year. Additionally, if the regional adjustment, when expressed as a single value, is negative, then no regional adjustment is applied to the ACO’s historical benchmark.

If an ACO generates losses for a performance year that meet or exceed its MLR (for two-sided model ACOs) or negative MSR (for one-sided model ACOs) under the three-way blended update factor, CMS will recalculate the ACO’s updated benchmark using the two-way national-regional blended update factor.

If an ACO generates savings using the two-way blend to update its benchmark but does not generate savings under the three-way blend, the ACO will neither be responsible for shared losses (if in a two-sided model) nor be eligible for shared savings for the applicable performance year, even if the savings generated exceed the ACO’s MSR.
