Medicare Advantage: $0 Premiums Disguise High Copays and Narrow Networks

Updated March 2026

Medicare Advantage advertises: $0 premiums, dental covered, vision covered, hearing covered. Original Medicare has premiums and covers none of that. So seniors switch to Advantage. What they don't see: out-of-pocket maximums of $6,500–$8,000 yearly, narrower networks (your doctor might not participate), prior authorization requirements for procedures, and coverage changing yearly. Your favorite plan today drops your doctor in January. A procedure approved this year needs authorization next year. The premium savings are real. Everything else is unstable and expensive.

What Is Medicare Advantage?

Medicare Advantage, also called Part C, is an alternative way to receive your Medicare benefits. Instead of staying in Original Medicare (Parts A and B), you can enroll in a private insurance plan approved by Medicare. These private plans contract with Medicare to provide all of your Part A and Part B coverage, usually with additional benefits.

Private insurers offering Medicare Advantage plans include major companies like UnitedHealthcare, Humana, Anthem Blue Cross, and others. Plans vary widely in cost, coverage, provider networks, and benefits, which is why comparing plans is essential.

Types of Medicare Advantage Plans

HMO (Health Maintenance Organization)

HMO plans require you to use providers within their network (except emergencies). You must choose a primary care physician who coordinates all your care. Out-of-network care is generally not covered. HMOs typically have lower premiums but less flexibility.

PPO (Preferred Provider Organization)

PPO plans offer more flexibility. You can see any provider, but you'll pay more for out-of-network care. You don't need a primary care physician. PPOs typically cost more in premiums but offer greater provider choice.

PFFS (Private Fee-for-Service)

PFFS plans are less common. You can see any provider who accepts the plan's payment terms. These plans are rare in most areas.

Key Differences Between Medicare Advantage and Original Medicare

Cost Structure: Medicare Advantage plans often have $0 premiums (in addition to your Part B premium), but charge copays and coinsurance for services. Original Medicare has lower copays but requires you to pay 20% coinsurance for most services.

Network Restrictions: Medicare Advantage restricts you to in-network providers (for HMOs) or charges more for out-of-network care. Original Medicare works with any provider who accepts Medicare.

Out-of-Pocket Maximums: Medicare Advantage has annual out-of-pocket maximums, protecting you from catastrophic costs. Original Medicare has no out-of-pocket cap—you could theoretically pay unlimited amounts.

Additional Benefits: Many Medicare Advantage plans include dental, vision, hearing, and gym memberships. Original Medicare covers none of these.

Prescription Drug Coverage: Medicare Advantage includes prescription drug coverage (Part D). With Original Medicare, you must enroll in a separate Part D plan.

Medicare Advantage in 2026: What's Changing

The 2026 budget proposals include potential Medicare sequestration cuts of up to $500 billion over ten years. These cuts would reduce provider payment rates, potentially affecting Medicare Advantage plan availability and benefits.

Key 2026 Changes: Sequestration cuts may reduce Medicare payments to insurance companies, which could mean fewer plans available in your area, higher premiums, or reduced benefits. Star ratings (quality measures) will continue to reward plans that perform well, affecting plan bonuses.

Step-by-Step: How to Choose a Plan

Step 1: Identify Your Doctors and Hospitals

Make a list of doctors, specialists, and hospitals you currently use or want to access. Check each plan's provider network to ensure your preferred providers are included. Pay special attention to specialists you see regularly—they must be in-network or you'll pay significantly more.

Step 2: Compare Costs

Look at three cost categories: monthly premiums, annual deductibles, and per-visit copays/coinsurance. Don't just focus on the lowest premium—high copays might mean you pay more overall. Consider your expected healthcare usage when evaluating costs.

Step 3: Evaluate Drug Coverage

If you take prescription medications, enter your drug list into each plan's formulary (drug list) to ensure your medications are covered. Pay attention to which tier your drugs are on (copay amounts) and whether there are quantity limits or prior authorization requirements.

Step 4: Check Star Ratings

Medicare publishes Star Ratings for each Medicare Advantage plan measuring quality of care, member satisfaction, and other factors. Plans with 4+ stars are considered high-quality. Use these ratings as one factor in your decision.

Step 5: Review Additional Benefits

Compare dental, vision, hearing, and wellness benefits across plans. Some plans offer full coverage; others offer minimal or no additional benefits. If you need these services, factor them into your decision.

When to Enroll

Open Enrollment Period for Medicare Advantage runs October 15 through December 7 each year. You can change plans during this period, even if you previously selected one. If you're turning 65 or newly eligible for Medicare, you have an Initial Enrollment Period of 7 months around your eligibility date.

Important: If you miss the Initial Enrollment Period or general Open Enrollment, you may have to wait until next year to change plans, with limited exceptions. Mark your calendar to ensure you don't miss the Open Enrollment deadline.

Comparing Plans: Use Medicare's Tools

Visit Medicare.gov and use the Plan Finder tool. You can enter your ZIP code, doctors, hospitals, and prescriptions to see personalized plan comparisons. This tool shows you specific costs for each plan based on your actual healthcare needs.

Compare at least three plans side-by-side before deciding. Look at the total estimated annual cost (premiums plus expected out-of-pocket costs), not just the monthly premium.

Questions to Ask Before Enrolling

Does the plan cover out-of-area emergency care?
Are there quantity limits on mental health or therapy services?
Does the plan cover hearing aids or require prior authorization?
What's the approval process for specialist referrals?
Does the plan cover care at the VA or tribal facilities if relevant?
What's the procedure for appealing a denied claim?
Are there restrictions on telehealth services?

The Bottom Line

Medicare Advantage can offer excellent value if you choose a plan that matches your healthcare needs and provider preferences. The $0 premiums and additional benefits appeal to many seniors, but you must carefully evaluate networks and drug coverage. With 2026 potentially bringing changes to plan availability and benefits due to sequestration cuts, comparing plans early in Open Enrollment is more important than ever.

Use Medicare.gov's Plan Finder, compare costs based on your actual healthcare needs, and don't hesitate to switch plans if a better option becomes available. Your health and finances deserve the time it takes to find the right plan.
