Oak Street Health and Aetna Team Up to Expand Access to Value-Based Care in Indiana and Michigan

Chicago, IL — April 9, 2019 — Oak Street Health, a network of primary care centers providing a new model of value-based primary care to Medicare patients, and Aetna, a CVS Health Company (NYSE: CVS) have entered into an innovative value-based network agreement in Indiana and Michigan. Effective April 1, 2019, Aetna® Individual Medicare Advantage members and retirees that receive coverage through Aetna Group Medicare Advantage plans will have access to Oak Street Health’s primary care centers.

Expanding our partnership with Aetna will bring our proven model of preventive, personalized care to Aetna’s members in Indiana and Michigan,” said Rafe Petty, division president of Oak Street Health. We couldn’t be more excited to introduce an additional 1.6 million Medicare-eligible Aetna members to our holistic approach to health. We look forward to seeing these members in our centers throughout Michigan and Indiana over the coming months.”

Oak Street Health’s community-based care model focuses on the overall value of health care for its patients. Its facilities feature more comprehensive services than a traditional doctor’s office. These include 24-hour access to a physician, flexible scheduling, more face time with doctors, community health and wellness events, state-of-the-art technology and a dedicated care team to coordinate all health needs. This proven strategy has reduced Medicare hospitalizations in other Oak Street facilities by more than 40 percent*.

Aetna is a leader in providing innovative ways to access care for our members, enabled by strong, collaborative provider partnerships with aligned incentives for all,” said Gregg Kimmer, executive director and general manager for Aetna Great Lakes Individual Medicare Advantage plans. By working together with Oak Street Health, we will be able to collectively help deliver improved outcomes and a superior experience to our Medicare members, meeting them in their communities where many of the conversations between patients and providers occur.”
