@jerce Thanks. Also ACO participants are per CMS.gov:
https ://www.cms.gov/priorities/innovation/key-concepts/accountable-care-and-accountable-care-organizations.
Groups of doctors, hospitals, and other health care professionals that work together to give patients high-quality, coordinated service and health care, improve health outcomes, and manage costs. ACOs may be in a specific geographic area and/or focused on patients who have a specific condition, like chronic kidney disease.
