The annual application period for the Medicare Shared Savings ACO program begins May 20 and will last through June 17. Accountable Care Organizations, or ACOs, interested in applying to the program in 2025 must meet this June 17 deadline.
After the initial application process, ACOs will need to submit additional or updated information by certain deadlines. For providers and physician groups, the most important of those deadlines is August 1, which is the final date that prospective ACO entities that submitted the first phase of the application will be able to add ACO participants to their participant lists.
