Oak Street Health clinics function as primary care providers within the Medicare network. They employ doctors, nurse practitioners, and physician assistants who see Medicare patients. The clinics typically focus on managing chronic conditions, preventive care, and routine health maintenance for older adults. Unlike some healthcare providers that limit their services, Oak Street Health maintains a broad scope of primary care services for Medicare-covered patients.
The organization has grown significantly over the past decade. As of recent reports, Oak Street Health serves hundreds of thousands of patients across its clinic network. The clinics accept various types of Medicare coverage, including Original Medicare (Parts A and B) and Medicare Advantage plans, though specific plans accepted may vary by location.
Understanding how Oak Street Health fits into the Medicare landscape matters for those seeking primary care services. The clinics operate on a fee-for-service or capitated model depending on the payment arrangement with different Medicare plans. This means they receive payment from Medicare or Medicare Advantage insurers for the services they provide to enrolled patients.
Practical Takeaway: Oak Street Health represents one option among many primary care providers in the Medicare network. Learning about their locations, services, and which Medicare plans they accept in your area can help you understand your healthcare options.
Many Oak Street Health clinics participate in Medicare Advantage plans, also called Medicare Part C. These plans are offered by private insurance companies approved by Medicare and provide all Medicare Parts A and B coverage, typically with additional benefits like prescription drug coverage and vision or dental services. Understanding how primary care providers work within these plans matters for Medicare beneficiaries.

Medicare Advantage plans usually require members to select a primary care provider (PCP) or be assigned one. The primary care provider coordinates most of your healthcare, and you typically must use doctors within the plan's network for covered services. Oak Street Health clinics may participate in multiple Medicare Advantage plans in their service areas, meaning you might find them available through different insurance options.
Different Medicare Advantage plans have different networks and benefits. A plan offered in one geographic area may include an Oak Street Health clinic, while another plan in the same area may not. Additionally, the same Oak Street Health clinic might participate in some Medicare Advantage plans but not others. When reviewing plan options, you can check which providers participate in each plan you're considering.
Selecting a primary care provider is an important decision because this doctor manages your overall care coordination. They see you for routine visits, manage chronic conditions, and typically provide referrals to specialists if needed. If you prefer to receive care from an Oak Street Health provider, you can look for plans where those clinics are in-network and available for you to select as your PCP.
Medicare Advantage plans have annual enrollment periods during which you can make changes. The general enrollment period typically runs from October 15 through December 7 each year. If you want to switch to a different plan or change your primary care provider, these timeframes are when changes become effective.
Practical Takeaway: Review the provider networks of any Medicare Advantage plans you're considering. Check whether Oak Street Health clinics are available in-network and whether you can select one as your primary care provider.
Beneficiaries enrolled in Original Medicare (Medicare Parts A and B) can also receive care at Oak Street Health clinics. Original Medicare is the traditional fee-for-service program run directly by the federal government. With Original Medicare, you're not required to select a primary care provider or stay within a specific network of doctors. This means you have more flexibility in choosing where to receive care, though you still benefit from finding providers who understand your complete medical history.

Oak Street Health clinics that accept Original Medicare participate as in-network providers, which means they have an agreement with Medicare regarding payment for services. When you visit an in-network provider like an Oak Street Health clinic with Original Medicare, you typically only pay your share of costs after Medicare pays its portion. Out-of-pocket costs may include copayments for office visits or coinsurance depending on your specific coverage and the services received.
With Original Medicare, there's no referral requirement to see a specialist, though your primary care provider—whether at Oak Street Health or elsewhere—may still recommend specialist care. You can see any doctor accepting Medicare without needing approval from another provider first. This structure differs from Medicare Advantage plans, which typically require referrals and restrict you to in-network providers.
Original Medicare doesn't include prescription drug coverage or vision and dental benefits, though you can purchase separate coverage for these services. Many beneficiaries with Original Medicare also purchase Medigap (supplemental insurance) to help cover costs that Original Medicare doesn't pay. Others may choose to enroll in a separate Part D prescription drug plan.
If you have Original Medicare and want to receive primary care at an Oak Street Health clinic, you can contact the clinic directly to schedule an appointment. No enrollment or registration beyond what's needed for any doctor visit is necessary. The clinic's administrative staff can verify your Medicare coverage and explain what you might owe for your visit.
Practical Takeaway: Original Medicare beneficiaries can seek care at Oak Street Health clinics that accept Medicare without needing to change their coverage type. Call ahead to confirm the clinic accepts your Medicare coverage and to understand what costs you might pay.
Oak Street Health clinics provide a range of primary care services typical of community health centers focused on serving seniors.

Chronic disease management represents a significant focus for Oak Street Health. Many older adults live with conditions like diabetes, hypertension, heart disease, COPD, or arthritis. Oak Street Health providers work with patients to develop treatment plans, monitor disease progression, and adjust medications as needed. Regular visits allow providers to track how well current treatments work and make changes to improve outcomes.
Preventive care services at Oak Street Health clinics typically include annual wellness visits (covered under Medicare), cancer screenings, cardiovascular health assessments, and vaccinations. The clinics often provide flu shots, pneumonia vaccines, and other immunizations recommended for older adults. Some clinics offer bone density screening and other age-appropriate preventive services.
Many Oak Street Health clinics feature on-site capabilities that reduce the need to visit multiple locations. Some clinics have in-house laboratory services, allowing blood work to be done during your visit. Certain locations offer basic radiology services. This consolidation of services can make healthcare management more convenient for patients who need multiple tests or evaluations.
Care coordination is another component of services at Oak Street Health. Providers work to communicate with specialists you may see elsewhere, review records from other healthcare providers, and ensure your various treatments don't conflict. This coordinated approach helps prevent gaps in care or duplication of services.
The specific services available may vary by clinic location. Some clinics may offer additional services like behavioral health support, care management for complex patients, or partnerships with community resources. Contacting your local Oak Street Health clinic can provide details about the exact services they provide.
Practical Takeaway: Learn what services your local Oak Street Health clinic provides by reviewing their website or calling directly. Understanding available services helps you determine if the clinic can meet your healthcare needs.
