Medicare Plans Comparison 2026: Which Type Is Right for You?

If you're comparing Medicare plans in 2026, the most important decision is whether to choose Original Medicare (paired with a Medigap supplement) or a Medicare Advantage plan. Original Medicare gives you maximum provider flexibility and predictable costs with a good Medigap plan; Medicare Advantage typically offers $0 or low premiums but restricts your network. We compared five Medicare plan types across cost, flexibility, coverage, and out-of-pocket risk to help you decide.

Last updated: April 2026. We review this guide annually and after each CMS announcement. Always verify current premiums and plan details at Medicare.gov.

How We Compared These Plans

We evaluated each Medicare plan type across five criteria:

Criteria	Weight	Why It Matters
Monthly cost	High	Directly affects your retirement budget every month
Out-of-pocket risk	High	One hospital stay can cost thousands without proper coverage
Provider access	High	Critical if you have existing doctors or specialists
Prescription coverage	Medium	Most beneficiaries need drug coverage
Simplicity	Medium	Easier plans reduce billing confusion and paperwork

1. Original Medicare (Part A + Part B) — Maximum Provider Freedom

Best for: Beneficiaries with complex medical needs, frequent travelers, or anyone who wants to see any Medicare-accepting doctor without referrals

Part A (hospital) premium: $0 for most people (requires 40 quarters of work history)
Part B (medical) standard premium: ~$185/month (2025 CMS rate; verify current rate at Medicare.gov)
Part B deductible: $257/year

Original Medicare is the federal health coverage program covering hospital stays (Part A) and doctor visits, outpatient care, and preventive services (Part B). After meeting the Part B deductible, Medicare pays 80% of approved costs — leaving you responsible for the remaining 20% with no annual cap. That unlimited 20% exposure is why most beneficiaries pair Original Medicare with a Medigap supplement and a standalone Part D drug plan.

Pros

• Any doctor or hospital in the U.S. that accepts Medicare — no network restrictions
• No referrals needed to see specialists
• Consistent, nationwide coverage — critical for snowbirds and frequent travelers

Cons

• No annual out-of-pocket maximum on its own — 20% coinsurance has no ceiling
• No prescription drug coverage (must add a separate Part D plan)
• No dental, vision, or hearing coverage

Who This Is Best For

Original Medicare suits people with established specialist relationships, those managing complex or chronic conditions, and frequent travelers who need consistent nationwide coverage. It is not ideal if you want a single plan that bundles Rx, dental, and vision — and the 20% coinsurance exposure without a Medigap supplement carries real financial risk if you are hospitalized.

2. Medicare Advantage HMO — Low Premiums, Managed Care

Best for: Healthy seniors living near a major metro area who want low monthly costs and don't mind using a network

Average monthly premium: ~$17/month (2025 CMS Medicare Advantage landscape data)
In-network out-of-pocket maximum: ≤$9,350/year (2025 CMS limit)

Medicare Advantage HMO (Health Maintenance Organization) plans contract with CMS to provide all Original Medicare benefits — and most plans add dental, vision, hearing, and prescription drug coverage. Roughly 54% of Medicare beneficiaries (33.8 million people) were enrolled in Medicare Advantage as of 2024, per KFF. HMO plans require you to choose a primary care physician and get referrals for specialists, and generally restrict coverage to in-network providers.

Pros

• Often $0 or very low monthly premiums
• Hard annual out-of-pocket maximum protects against catastrophic costs
• Frequently bundles dental, vision, hearing, and Part D drug coverage in one plan

Cons

• Restricted to in-network providers — out-of-network care typically not covered except emergencies
• Requires primary care referrals for specialist visits
• Plan availability and quality varies significantly by county

Who This Is Best For

Medicare Advantage HMO is a strong choice for relatively healthy seniors who live in an area with a robust plan network, are comfortable with managed care, and want low premiums with a cost ceiling. It is not ideal for people with existing out-of-network specialists, frequent travelers, or anyone managing complex conditions requiring multiple specialists.

---

3. Medicare Advantage PPO — Network Flexibility with Cost Protection

Best for: Seniors who want Medicare Advantage's cost cap but occasionally need out-of-network providers

Average monthly premium: ~$30–$80/month (higher than HMO, lower than Medigap)
Out-of-pocket maximum: ≤$9,350/year in-network; higher OOP max applies for out-of-network care

Medicare Advantage PPO (Preferred Provider Organization) plans allow you to see out-of-network providers at a higher cost-share — no referrals required. This gives more flexibility than an HMO while still providing the hard out-of-pocket maximum that Original Medicare lacks alone. PPO premiums run higher than HMO plans but remain lower than most Medigap supplement premiums.

Pros

• Out-of-network coverage available (at higher cost-share) with no referrals required
• Hard annual out-of-pocket maximum on both in-network and out-of-network care
• Often includes dental, vision, hearing, and Part D drug coverage

Cons

• Higher premiums than Medicare Advantage HMO plans
• Out-of-network cost-sharing can still be substantial during major illness
• Plan networks and formularies change annually — requires review each fall

Who This Is Best For

Medicare Advantage PPO works well for seniors who want cost protection but value the flexibility to see out-of-network providers without a referral. It is the middle ground between an HMO's low cost and Original Medicare's unlimited access. Not ideal for heavy travelers who need consistent nationwide coverage or people whose primary specialists are consistently out-of-network.

4. Medicare Supplement Plan G (Medigap) — Predictable Costs, Maximum Coverage

Best for: Beneficiaries with significant or ongoing healthcare needs who want predictable costs and Original Medicare's provider freedom

Typical monthly premium: $100–$200/month (varies by age, state, and insurer)
Annual out-of-pocket after Plan G: $257 (the Part B deductible only, as of 2025)

Medigap Plan G is the most comprehensive Medicare Supplement plan available to new Medicare enrollees. (Plan F was discontinued for new enrollees after January 1, 2020.) Plan G covers the Part A deductible, coinsurance, and hospital costs, plus Part B coinsurance and excess charges — leaving you responsible only for the annual Part B deductible. Importantly, Medigap coverage is federally standardized: every Plan G from every insurer offers identical benefits, so you compare on price alone.

Pros

• Near-zero out-of-pocket costs beyond the Part B deductible and your monthly premium
• Works with any Medicare-accepting provider in the U.S. — no networks
• Federally standardized coverage — shop by price among any licensed insurer

Cons

• Higher monthly premium than most Medicare Advantage plans
• Does not include drug coverage — must add a separate Part D plan
• No dental, vision, or hearing coverage included
• Premiums typically increase as you age

Who This Is Best For

Medigap Plan G is ideal for seniors with ongoing medical needs, those managing chronic conditions, or anyone who values financial predictability and wants to avoid network restrictions. It generally makes economic sense for people who expect above-average healthcare utilization. People in excellent health with minimal medical needs may find Medicare Advantage's lower premiums more cost-effective overall.

5. Medicare Part D (Standalone Prescription Drug Plan) — Rx Coverage for Original Medicare Enrollees

Best for: Anyone enrolled in Original Medicare or Medigap who takes prescription medications

Average basic premium: ~$46.50/month (2025 CMS data)
Annual out-of-pocket cap: $2,000 (effective 2025 under the Inflation Reduction Act)

Medicare Part D provides outpatient prescription drug coverage through private plans contracted with CMS. If you have Original Medicare with or without a Medigap supplement, you must add a standalone Part D plan to get drug coverage. The Inflation Reduction Act capped Medicare Part D out-of-pocket costs at $2,000 per year starting in 2025 — a meaningful protection for beneficiaries on high-cost specialty medications.

Pros

• $2,000 annual out-of-pocket cap on prescription costs (IRA provision, 2025+)
• Compare plans by your specific drug list at Medicare.gov to find lowest annual cost
• Low-Income Subsidy (Extra Help) available for qualifying beneficiaries

Cons

• Additional monthly premium added on top of Part B premium
• Formularies change annually — coverage for your specific drugs may shift
• Tier structures and pharmacy networks add complexity

Who This Is Best For

A standalone Part D plan is essential for Original Medicare and Medigap enrollees who take prescription medications. Even beneficiaries who currently take no medications should consider a low-premium plan: delaying Part D enrollment without creditable drug coverage triggers a permanent late enrollment penalty of 1% of the national base premium per month delayed.

How We Researched This

This guide draws on the CMS Medicare & You 2025 Handbook, CMS Medicare Advantage and Part D Landscape Data (2025), KFF Medicare Policy research, and CMS Part D enrollment and premium reports. We compared plan types rather than individual plans because specific plan availability and pricing varies by county and changes each year. We excluded short-term health plans and non-Medicare alternatives as they do not provide Medicare-creditable coverage. Last updated: April 2026. We review this guide annually after CMS announces the following year's rates and plan data.

Frequently Asked Questions

What is the difference between Medicare Advantage and Original Medicare?

Original Medicare is the federal program (Part A and Part B) that lets you see any Medicare-accepting provider nationwide with no referrals required, but it has no annual out-of-pocket limit. Medicare Advantage is private insurance approved by CMS that must cover everything Original Medicare covers — and typically adds dental, vision, and drug coverage — but restricts you to a provider network and requires prior authorizations for some services.

When can I enroll in Medicare?

Your Initial Enrollment Period is a 7-month window: 3 months before your 65th birthday month, your birthday month, and 3 months after. Annual Open Enrollment runs October 15 through December 7 and lets you switch plans for the following year. Missing your Initial Enrollment Period without qualifying for a Special Enrollment Period can result in permanent late enrollment penalties on Part B and Part D.

Can I switch from Medicare Advantage back to Original Medicare?

Yes, during Annual Enrollment (October 15–December 7) or the Medicare Advantage Open Enrollment Period (January 1–March 31). However, if you switch back to Original Medicare and want a Medigap plan, insurers in most states can require medical underwriting after your initial enrollment window — potentially leading to higher premiums or denial based on your health history.

Is Medigap Plan G worth the higher premium?

For beneficiaries with significant medical needs, Plan G typically pays for itself. Without a Medigap plan, Original Medicare's 20% coinsurance has no ceiling — a major hospitalization or specialist treatment course can cost $5,000–$20,000 out of pocket. Whether Plan G is worth the premium depends on your health utilization, risk tolerance, and whether provider choice flexibility matters to your care situation.

Does Medicare cover dental and vision?

Original Medicare does not cover routine dental, vision, or hearing care. Many Medicare Advantage plans include these benefits, though coverage depth varies widely by plan. Standalone dental and vision insurance plans can be purchased separately by Original Medicare and Medigap enrollees.

What is the Medicare Part D late enrollment penalty?

If you go 63 or more continuous days without creditable drug coverage after becoming eligible for Part D, you will owe a permanent penalty equal to 1% of the national base beneficiary premium for each month you delayed. This is added to your monthly Part D premium for as long as you have Medicare — so a 24-month delay adds roughly 24% to your base Part D premium permanently.

What is Extra Help for Medicare Part D?

Extra Help (also called the Low-Income Subsidy) is a federal program that assists people with limited income and resources in paying for Part D premiums, deductibles, and copays. Eligibility is based on income and asset thresholds updated annually by CMS. Apply through the Social Security Administration, your state Medicaid office, or a SHIP (State Health Insurance Assistance Program) counselor at no cost.
