Who Offers Medicare Advantage Plans? 2026 Providers List

What Is a Medicare Advantage Plan (Part C)?

Medicare Advantage plans-often referred to as Medicare Part C-are health insurance offerings provided by private insurance companies that have been approved by the Centers for Medicare & Medicaid Services (CMS). Unlike Original Medicare, which consists of Part A (hospital insurance) and Part B (medical insurance), Medicare Advantage plans bundle these benefits, frequently including Part D (prescription drug coverage) and a range of extra features. These can include dental, vision, hearing coverage, and wellness programs that Original Medicare does not offer.

Every Medicare Advantage plan must offer at least the same level of coverage as Original Medicare, but costs, provider networks, and benefits can differ dramatically between plans and locations. For 2026, nearly all Medicare beneficiaries will have access to multiple plan choices, marking the highest availability yet.

• HMO (Health Maintenance Organization): Requires primary care referrals and uses a defined provider network for most services.
• PPO (Preferred Provider Organization): Offers more flexibility in choosing providers and permits some out-of-network care at higher costs.
• Other types include Private Fee-for-Service (PFFS) and Special Needs Plans (SNPs), which focus on specific groups or medical conditions.

Extra benefits such as dental, vision, and hearing, $0 premium options, and prescription drug coverage make Part C very appealing to many enrollees. To learn more about how Medicare enrollment works and what to consider, visit How Do I Learn About Medicare Coverage and Enrollment?.

National Medicare Advantage Providers

Medicare Advantage plans are only available through private insurance companies that contract with Medicare. In 2026, the largest and most recognized national Medicare Advantage providers will continue to offer plans across broad regions, often with varied network sizes, plan types, and additional features.

• UnitedHealthcare: The largest national provider by enrollment, known for its expansive provider network and wide availability. It frequently features $0 premium plans and robust supplemental benefits.
• Humana: Broad choice of plans with innovative features like Part B Giveback (a monthly reduction on Part B premiums), strong pharmacy networks, and increasingly competitive star ratings.
• Aetna: Offers high ratings for customer satisfaction and strong wellness-focused extras, such as fitness memberships and vision benefits.
• Cigna (HealthSpring): Known for affordable options and targeted plans, especially in specific regions.
• Kaiser Permanente: Renowned for its integrated care model, although its plans are limited to certain states. Consistently high star ratings and above-average preventive care outcomes.
• Blue Cross Blue Shield/Anthem/Elevance Health: Blue-branded plans, like Anthem (in some states) and Elevance Health, lean into broad network access and solid local partnerships.
• Devoted Health: A newer but fast-expanding company, praised for innovation and exceptional customer service.
• SCAN Health Plan: Niche player with extremely high satisfaction rates, especially in states like California and Nevada.

All of these Medicare Advantage companies adhere to CMS requirements and must report quality through the CMS Star Ratings program, a helpful metric for comparing plan performance. An important aspect of choosing among the best Medicare Advantage companies is understanding the differences between HMO and PPO offerings, especially regarding network flexibility and out-of-pocket costs.

Regional and Local Medicare Advantage Providers

In addition to the large national providers, many regional and local insurers offer Medicare Advantage plans tailored to specific states, counties, or even neighborhoods. These companies often partner with local healthcare systems to provide more personalized service and sometimes include benefits not found in larger plans.

• Examples include:
  • Local Blue Cross or Blue Shield affiliates
  • Independent health plans, such as HealthPartners, Geisinger, or Molina Healthcare
  • Regional hospital-system plans, e.g., UCLA Health or UPMC for Life

Regional providers often shine in customer satisfaction, offering smaller, tighter networks that cater to local preferences. They may focus on additional supports for managing chronic conditions, lower copays for local providers, or specialty coverage relevant to nearby populations.

How to Compare Medicare Advantage Plans

Coverage and Benefits

Start your comparison by making sure the plan covers all your essential medical needs. This means hospital, medical, and-if needed-prescription drug coverage. Many plans also feature valuable supplemental benefits, such as gym memberships, over-the-counter allowances, and telehealth services. Look closely at what each plan includes, as extra benefits are a chief selling point and a source of major differences.

Costs: Premiums, Copays, Deductibles, and Out-of-Pocket Maximums

While many Medicare Advantage plans offer $0 premiums, it’s crucial to compare additional expenses such as deductibles, copays, coinsurance, and out-of-pocket maximums. Make sure also to factor in any Part B premiums you’re still responsible for, unless the plan includes a giveback feature. Comparing a few plans side-by-side in a table can help clarify the true annual costs.

Provider Network Size and Access

Each Medicare Advantage plan maintains its unique provider network. This network determines which doctors, hospitals, and other specialists you can visit at the plan’s lower cost-sharing rates. HMOs limit members to in-network providers for most care, while PPOs permit some out-of-network options, though usually at a higher cost. Checking network size and the presence of your preferred providers is a vital step that can help avoid unexpected bills or the inconvenience of switching health care professionals mid-year. For a comparison of plan types, see the table below:

Plan Type	Network Requirement	Referral Needed	Out-of-Network Coverage?
HMO	In-network only (except emergencies)	Yes	Limited
PPO	In-network preferred, out-of-network allowed at higher cost	No	Yes
PFFS	No formal network (provider must accept plan terms)	No	Yes
SNP	Specific provider networks	Varies	Limited

Prescription Drug Coverage

Not all Medicare Advantage plans include drug coverage. Carefully review each plan’s formulary (drug list) to make sure your prescriptions are covered at an affordable rate. Regional resources like Continuous Glucose Monitoring Medicare Coverage 2025 may help in evaluating coverage for chronic conditions or specific medications.

CMS Star Ratings and Customer Satisfaction

The CMS Star Ratings (1-5 stars) provide a trustworthy, government-standardized measure of plan quality. Ratings reflect preventive service use, chronic care support, complaint rates, and customer feedback. Plans with 4 or more stars often deliver better member experiences and higher overall value.

Tools and Resources to Compare Plans

The official Medicare Plan Finder allows you to input your ZIP code, list of medications, and favorite providers to get tailored results. Be sure to review each plan’s Summary of Benefits and Evidence of Coverage documents for complete details. Licensed agents, local service offices, and state SHIP counselors can offer additional advice.

How to Check if Your Doctor or Hospital Is In-Network

Being sure your preferred doctor or hospital is in-network can save you money and hassle. For 2026, advances in digital tools are making this process easier than ever:

• Visit the official Medicare Plan Finder at Medicare.gov and use the updated provider directory tool to search for doctors, specialists, or hospitals in your area.
• Contact the insurance company directly through their member portal or customer service line to verify provider status.
• Ask your doctor’s office if they participate in your chosen plan’s network for the coming year.

Provider networks can change any year, so it is wise to confirm annually-even if you’ve had the plan previously.
