Oak Street Health centers function as primary care medical homes rather than insurance companies themselves. Instead, they contract with established Medicare Advantage insurers such as United Healthcare, Humana, and Aetna to serve enrolled members. This distinction matters significantly because it means Medicare beneficiaries don't choose Oak Street Health directly as their insurance plan. Rather, they select a Medicare Advantage plan that includes Oak Street Health as an in-network provider, or they may be assigned to an Oak Street Health center depending on their plan selection.

The organization operates medical centers in numerous states including California, Florida, Illinois, Indiana, Ohio, Pennsylvania, Texas, and others, with continuous expansion. As of recent years, Oak Street Health serves hundreds of thousands of Medicare beneficiaries through their center network. Their model emphasizes preventive care, chronic disease management, and coordination across healthcare services. Many Medicare beneficiaries find value in this integrated approach because it centralizes their primary care with extended appointment times and care coordination support.

When exploring Oak Street Health options, beneficiaries should recognize that their experience depends largely on which Medicare Advantage plan they select. Different plans offer varying benefit structures, copayment amounts, prescription drug coverage details, and supplemental services. Some plans partnering with Oak Street Health include dental, vision, or hearing benefits that others don't provide. The specific benefits and costs depend entirely on the individual plan selected and the beneficiary's circumstances.

Practical Takeaway: Review your Medicare Advantage plan documents to confirm whether Oak Street Health centers participate as in-network providers. Contact your plan directly or visit their website to identify participating Oak Street Health locations in your service area and understand what benefits apply to services received there.

Types of Medicare Advantage Plans Offering Oak Street Health Access

Medicare Advantage plans, also called Part C plans, allow private insurers to offer coverage of Medicare-covered services. These plans must cover at minimum everything Original Medicare covers, but they often add supplemental benefits. Many Medicare Advantage plans contracting with Oak Street Health provide comprehensive primary care access through their centers as part of the plan's network infrastructure. Understanding the different plan types helps beneficiaries make informed decisions about their coverage options.

Health Maintenance Organization (HMO) plans represent one common structure for Medicare Advantage plans featuring Oak Street Health. These plans typically require members to use in-network providers, making Oak Street Health centers ideal resources for HMO participants. HMO members generally pay lower premiums and copayments compared to other plan types but have less flexibility in provider selection. Many Oak Street Health members find HMO plans advantageous because the centers' comprehensive services reduce the need to seek care elsewhere. Some HMO plans include extended primary care visits at Oak Street Health locations, with appointment times sometimes exceeding one hour compared to standard fifteen to twenty-minute visits.

Preferred Provider Organization (PPO) plans offer another Medicare Advantage structure that may include Oak Street Health in their networks. PPO plans provide greater flexibility, allowing members to visit out-of-network providers, though typically at higher out-of-pocket costs. PPO participants using Oak Street Health as their primary care provider still benefit from in-network rates and coordinated care services, but they maintain the option to see other providers without plan authorization. This flexibility appeals to beneficiaries who want comprehensive primary care at Oak Street Health but desire additional choice in specialist selection or care settings.

Regional Preferred Provider Organizations (RPPOs) and Special Needs Plans (SNPs) may also include Oak Street Health participation. RPPOs limit geographic service areas while maintaining PPO-style flexibility within those regions. Certain SNPs focus on specific populations such as individuals with chronic conditions, dual Medicare-Medicaid coverage, or those living in institutional settings. Some beneficiaries with particular health conditions or circumstances discover that specialized Medicare Advantage plans incorporating Oak Street Health provide services specifically designed for their needs, such as enhanced care coordination for heart disease, diabetes, or behavioral health conditions.

Practical Takeaway: During Medicare's Annual Enrollment Period (typically October 15 to December 7), use Medicare.gov's plan comparison tool to search for plans in your area that include Oak Street Health in their networks, then compare the plan types, costs, and additional benefits offered by each option.

Primary care services form the foundation of Oak Street Health's offerings, including office visits with physicians, nurse practitioners, and physician assistants. The organization's care model emphasizes extended appointments, with many visits scheduled for sixty minutes or longer compared to industry averages. These longer appointments allow providers to conduct more thorough assessments, discuss multiple health concerns, and develop personalized care plans. Beneficiaries can address chronic disease management, acute illness concerns, preventive health screenings, and medication reviews during these visits. Many patients report satisfaction with the opportunity to discuss health concerns comprehensively rather than feeling rushed through appointments.

Preventive services at Oak Street Health centers align with Medicare-covered preventive benefits, including annual wellness visits, cancer screenings, cardiovascular risk assessments, and diabetes screenings. These preventive services help identify health conditions early when treatment often proves most effective. Many Medicare Advantage plans partnering with Oak Street Health cover these preventive services without copayments when provided at in-network locations. Beneficiaries can explore the specific preventive benefits covered under their individual plans to understand what services may help their personal health situation.

Care coordination and management represent significant value components at Oak Street Health. Care coordinators help beneficiaries navigate healthcare systems, arrange specialist referrals, ensure medication adherence, and manage complex chronic conditions. This coordination often reduces hospitalizations and emergency department visits for beneficiaries with multiple chronic diseases. Telehealth services extend access to primary care providers and care coordinators beyond in-person center visits, allowing convenient consultations for non-urgent concerns, prescription refills, and follow-up discussions. Social services coordinators assist with identifying community resources, transportation services, housing assistance, and other social determinants that affect health.

Some Oak Street Health centers provide on-site laboratory and imaging services, reducing the need for separate lab appointments and allowing faster turnaround on test results. Behavioral health screening and referral services help identify mental health and substance use concerns, with some centers offering direct mental health counseling. Medication management services include comprehensive medication reviews to identify potential interactions or side effects. Home-based care programs serve homebound beneficiaries who have difficulty accessing office-based services.

Practical Takeaway: Schedule an initial appointment or center visit to learn about specific services available at your local Oak Street Health center, including whether they offer telehealth, on-site labs, behavioral health services, and transportation assistance that could support your individual healthcare needs.

Costs, Copayments, and Out-of-Pocket Expense Structures

Understanding the financial structure of Medicare Advantage plans that include Oak Street Health is essential for budgeting healthcare expenses and making informed coverage decisions.

Monthly premiums represent the first cost component for Medicare Advantage plans. Some plans partnering with Oak Street Health charge no premium beyond the standard Medicare Part B premium, while others require additional monthly payments ranging from modest amounts to several hundred dollars depending on the plan and geographic location. Premium amounts can change annually, so beneficiaries should review updated premium information during each enrollment period. Many beneficiaries find that plans with no additional premium still provide substantial value through supplemental benefits and lower out-of-pocket costs compared to plans with higher premiums.

Copayment structures define what beneficiaries pay for specific services at the point of care. Office visits to Oak Street Health centers may involve copayments ranging from zero dollars (for certain preventive visits) to fifty dollars or more depending on the specific
