Under the Medicare Advantage Program, Medicare beneficiaries have the option to obtain their health care through privately-operated insurance plans known as MA plans, some of which contract with health care providers, including Oak Street, to provide their plan members with primary care services. The United States alleged that the Oak Street Health payments to the agents improperly incentivized them to base their referrals and recommendations on the financial motivations of Oak Street Health and of the agents rather than the best interests of seniors. In addition to this matter, the Justice Department continued to litigate a number of other cases involving the Medicare Advantage program, including actions against UnitedHealth Group, Elevance Health (formerly Anthem), and the Kaiser Permanente consortium.
