Guidance

An ACO Participant is an entity identified by a Medicare-enrolled TIN through which one or more ACO providers/suppliers bill Medicare. The document describes the requirements that an ACO participating in or applying to the Shared Savings Program must follow with respect to its ACO Participant List, ACO Provider/Supplier List, and ACO Participant Agreement. Currently Participating ACOs may modify their ACO Participant List and associated agreements for the upcoming performance year during established timeframes.

Only Shared Savings Program ACOs that are currently participating in or applying to certain Shared Savings Program performance-based risk tracks have the opportunity to apply for a waiver of the SNF 3-Day Rule, and they must apply separately for the waiver during the annual application process..

The ACO Primary Care Flex Model (ACO PC Flex Model) is a voluntary model that will focus on primary care delivery in the Shared Savings Program. It will test how prospective payments and increased funding for primary care in ACOs impact health outcomes, quality, and costs of care. The flexible payment design will empower participating ACOs and their primary care providers to use more innovative, team-based, person-centered and proactive approaches to care.

ACOs who are interested in the  ACO PC Flex Model must first apply the Shared Savings Program. ACOs who do not have an application to begin a new agreement period will not be able to respond the ACO PC Flex Model Request for Application.
