Best Medicare Advantage Plans by State 2026: Carrier Guide

Medicare Advantage (Part C) now covers more than half of all Medicare beneficiaries — over 33 million Americans enrolled in 2026. These private insurance plans offer a compelling alternative to Original Medicare by bundling Part A, Part B, and usually Part D drug coverage into a single plan with an out-of-pocket cap that Original Medicare lacks.

This guide covers how Medicare Advantage plans are structured, which carriers dominate by star rating, how benefits vary state by state, and what questions to ask before enrolling.

How Medicare Advantage Plans Work

Medicare Advantage plans are offered by private insurers approved by CMS (Centers for Medicare and Medicaid Services). You still pay your Medicare Part B premium, but the plan assumes responsibility for your care within its network.

Four plan types:

Best Medicare Advantage Plans by State 2026: Carrier Ratings & Costs
Sponsored
  • HMO (Health Maintenance Organization): Restricted to in-network providers; referrals required for specialists. Lowest premiums.
  • PPO (Preferred Provider Organization): Can see any Medicare provider (in-network at lower cost); no referrals needed. Higher premiums.
  • PFFS (Private Fee-for-Service): Provider must accept plan terms at each visit. Limited availability.
  • SNP (Special Needs Plan): Designed for people with specific chronic conditions, dual Medicare/Medicaid eligibility, or institutional care needs.

Top Medicare Advantage Carriers by CMS Star Rating (2026)

CMS rates Medicare Advantage plans on a 1–5 star scale based on quality measures including preventive care rates, member satisfaction, and chronic disease management.

Carrier Average Star Rating Enrollment (millions) Plan Types Key Strength
Kaiser Permanente 4.9 4.0 HMO Highest quality scores; integrated care
UnitedHealthcare 4.0 8.9 HMO, PPO, SNP Largest network; most markets
Humana 4.2 5.3 HMO, PPO, PFFS Dental/vision bundling
Aetna (CVS) 4.0 3.7 HMO, PPO, SNP Pharmacy integration
Blue Cross Blue Shield 4.1 6.2 HMO, PPO Local market depth; regional reliability
Cigna 3.8 0.9 HMO, PPO Competitive pricing in target markets
Centene/WellCare 3.5 2.4 HMO Low-income/Medicaid-eligible populations

Star rating caveat: Kaiser Permanente’s 4.9 rating is impressive but its HMO-only model with integrated care systems limits geographic availability to California, Colorado, Georgia, Hawaii, Maryland/DC/Virginia, Oregon/Washington, and select markets.

  • California — Strong urban competition; Kaiser dominant in many markets
  • New York — Large enrollment base with strong competition in NYC, Long Island, and Westchester

Medicare Advantage vs Medigap: The Decision Framework

Choose Medicare Advantage if:

  • You want supplemental benefits (dental, vision, hearing, OTC, gym)
  • You are comfortable with a provider network
  • You prefer predictable copays over premium costs
  • You are relatively healthy and local to your providers

Choose Medigap (Plan G or N) if:

  • You travel frequently or have providers across state lines
  • You have complex medical needs requiring specialist access
  • You want predictable minimal cost-sharing at point of care
  • You can afford higher monthly premiums for lower treatment costs

Medicare Advantage Enrollment Periods

Period Dates What You Can Do
Annual Enrollment Period (AEP) Oct 15 – Dec 7 Join, switch, or drop any MA plan
Open Enrollment Period (OEP) Jan 1 – Mar 31 Switch between MA plans or return to Original Medicare
Initial Enrollment Period 3 months before to 3 months after 65th birthday First time enrollment
Special Enrollment Periods Various triggers (move, loss of coverage) Change outside standard periods

How Medicare Advantage Affects Retirement Planning

The choice between Medicare Advantage and Medigap has significant financial implications over a multi-decade retirement. A retiree who chooses a $0 premium Medicare Advantage plan versus a $175/month Plan G generates $2,100/year in premium savings — but may face higher point-of-care costs in high-utilization years.

Over a 20-year retirement, modeling this trade-off against your savings and projected health utilization is worthwhile. Use our Compound Interest and Savings Goal Calculator to see how premium savings compound when invested versus the cost of expected copays in a higher-utilization year.

Frequently Asked Questions

Can I see any doctor with Medicare Advantage? With HMO plans: generally no — you must use in-network providers. With PPO plans: yes, but out-of-network care costs more. For complete provider freedom, Original Medicare + Medigap is the right choice.

Does Medicare Advantage cover out-of-state care? Most HMO plans cover emergency care nationally but routine/specialist care only in-network. PPO plans provide broader out-of-network access at higher cost. Kaiser plans cover emergencies nationwide but routine care only in Kaiser regions.

Can I disenroll from Medicare Advantage? Yes. During the Annual Enrollment Period (Oct 15–Dec 7), you can switch to a different MA plan or return to Original Medicare + Medigap. Be aware that returning to Original Medicare outside your Medigap open enrollment period may subject you to medical underwriting in most states.

What is the star rating system? CMS rates plans 1–5 stars annually based on quality measures. Plans with 4+ stars receive higher CMS bonus payments, which they often pass on as richer benefits. Prioritizing 4+ star plans is a sound starting point.

What is the OTC (over-the-counter) allowance? Many Medicare Advantage plans include a quarterly or monthly credit ($25–$300) that can be spent on approved over-the-counter health products — vitamins, pain relievers, first aid supplies, and sometimes home health equipment. This benefit alone can be worth $100–$1,200/year.
