NAACOS is pleased to release the updated MSSP ACO Directory, a favorite member resource. The directory contains descriptive and contact information for Medicare Shared Savings Program (MSSP) ACOs. The directory succinctly organizes publicly available information from multiple years and sources into one concise and easy to navigate resource. The information includes attributes such as each ACO’s beneficiary size, shared savings, and quality performance scores. The resource includes all MSSP ACOs that were in operation in 2021. This file is updated every year after the release of the Public Use File from the previous year. This usually occurs sometime in the fall. The current version is accurate as of the 2021 Public Use File and will be updated for 2022 later this year when that information becomes available.

This resource is available to NAACOS members and partners – to receive the directory please complete this form.
