Choosing between Medicare Advantage and Original Medicare is one of the biggest healthcare decisions you will make at 65. Both cover the same core services, but the way they deliver coverage, restrict your choices, and charge you is fundamentally different. As of 2026, more than 35 million people are enrolled in Medicare Advantage, representing roughly 54% of all Medicare beneficiaries. That shift happened for real reasons, but Original Medicare is still the better fit for a large portion of seniors.
Quick Answer: Original Medicare (Parts A and B) gives you the freedom to see any doctor or hospital in the country that accepts Medicare, with no network restrictions. Medicare Advantage (Part C) is sold by private insurers, often at lower upfront cost, and typically bundles drug, dental, vision, and hearing coverage, but restricts you to a provider network. Neither is universally better. The right choice depends on your health needs, budget, where you live, and how much you travel.
This guide breaks down the real differences, the actual 2026 costs, and the questions that help you decide.
What Is Original Medicare?
Original Medicare is the federal government program that has existed since 1965. It has two parts:
- Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and limited home health services. Most people pay $0 premium for Part A if they or their spouse worked and paid Medicare taxes for at least 10 years.
- Part B covers outpatient services: doctor visits, lab work, preventive care, durable medical equipment, and outpatient procedures. The standard Part B premium for 2026 is $202.90 per month.
Original Medicare does not cover prescription drugs (that requires a separate Part D plan), routine dental, routine vision, hearing aids, or long-term care.
Original Medicare 2026 Cost Summary
| Cost Type | 2026 Amount |
|---|
| Part A premium (most people) | $0/month |
| Part A hospital deductible | $1,736 per benefit period |
| Part A coinsurance (days 61-90) | $434/day |
| Part A skilled nursing (days 21-100) | $217/day |
| Part B premium (standard) | $202.90/month |
| Part B annual deductible | $283 |
| Part B coinsurance | 20% of approved costs |
| Out-of-pocket maximum | No cap (unlimited exposure) |
The most important line in that table is the last one. Original Medicare has no out-of-pocket maximum. A serious illness or extended hospital stay can result in very large bills. Most people who choose Original Medicare add a Medigap (Medicare Supplement) policy to cap their exposure, which adds another $100-$300+ per month depending on the plan and your state.
IRMAA: Higher Earners Pay More for Part B
If your income exceeds certain thresholds, you pay more for Part B and Part D. The surcharge is called the Income-Related Monthly Adjustment Amount (IRMAA). For 2026, the thresholds are:
| Filing Status | MAGI Threshold | Additional Monthly Premium |
|---|
| Individual | Over $109,000 | $81.20+ |
| Married filing jointly | Over $218,000 | $81.20+ |
| Individual | Over $137,000 | $203.90+ |
| Individual (top tier) | Over $500,000 | $487.00+ |
IRMAA applies to both Original Medicare and Medicare Advantage. Your 2024 tax return income determines your 2026 IRMAA.
What Is Medicare Advantage?
Medicare Advantage (also called Part C) is Medicare coverage delivered through private insurance companies that contract with CMS. You still have Medicare, but a private plan manages your benefits. In 2026, beneficiaries have an average of 32 Medicare Advantage prescription drug plans to choose from.
Medicare Advantage plans must cover everything Original Medicare covers. Most also add:
- Prescription drug coverage (Part D, bundled in)
- Routine dental
- Routine vision and eyewear
- Hearing aids
- Fitness memberships (SilverSneakers and similar programs)
- Over-the-counter allowances
- Transportation to medical appointments
Almost all Medicare Advantage plans (98%+) include dental, vision, and hearing benefits that Original Medicare does not cover at all.
Medicare Advantage 2026 Cost Summary
| Cost Type | Typical Range |
|---|
| Monthly premium | $0 to $100+ (many are $0) |
| Maximum out-of-pocket (2026 cap) | Up to $9,250 for in-network services |
| Deductibles | Varies by plan; many have $0 for primary care |
| Copays/coinsurance | Fixed amounts per service type |
| Drug coverage | Usually included |
The $9,250 MOOP is the regulatory ceiling CMS sets for 2026. Individual plans set their own MOOP at or below that number. Once you hit it, the plan covers 100% of covered services for the rest of the year.
Note: You still owe your Part B premium ($202.90/month standard) even when enrolled in Medicare Advantage. That premium goes to Medicare, not to the plan. Some plans offer a "Part B premium reduction" as a supplemental benefit; about 32% of plans offer this in 2026.

Pros and Cons of Original Medicare
Pros
No network restrictions. You can see any doctor, specialist, or hospital in the country that accepts Medicare. This matters if you travel frequently, live in a rural area with few in-network providers, or have specialists you rely on.
Predictable with a Medigap policy. Add a Medigap plan and your costs become very predictable. You know exactly what you will pay no matter how sick you get.
No referrals. You can self-refer to any specialist without a gatekeeper. If you need to see a cardiologist, rheumatologist, or oncologist, you can book directly.
Guaranteed Medigap enrollment at 65. When you first enroll in Medicare, you have a 6-month guaranteed open enrollment period for Medigap. Insurers cannot deny you or charge more based on health history during this window. After it closes, they can reject you or charge higher premiums in most states.
No prior authorization requirements for most services.
Cons
No prescription drug coverage. You need a separate Part D plan, adding cost and complexity.
No dental, vision, or hearing coverage. These can be significant expenses in retirement, and you pay entirely out of pocket unless you buy supplemental insurance.
No out-of-pocket maximum. A major illness without Medigap can be financially devastating.
Medigap adds cost. Good Medigap policies (Plan G is the most comprehensive available to new enrollees) can cost $100-$300+ per month, depending on your age and state.
Higher upfront premiums overall. The combined cost of Part B + Part D + Medigap is usually higher than a Medicare Advantage plan premium.
Pros and Cons of Medicare Advantage
Pros
Lower upfront cost. Many Medicare Advantage plans carry $0 premiums beyond your Part B payment. The total monthly outlay can be hundreds of dollars less than Original Medicare plus Medigap.
Extra benefits included. Dental, vision, hearing, fitness programs, OTC allowances, and transportation are bundled in most plans. These benefits have real dollar value if you use them.
Out-of-pocket cap. The $9,250 MOOP limit protects you from catastrophic costs. Original Medicare has no such protection without Medigap.
Drug coverage bundled in. Most Medicare Advantage plans include Part D, simplifying your coverage.
Coordinated care. HMO-style plans with a primary care physician can coordinate your care more effectively, which matters if you have multiple chronic conditions.
Cons
Network restrictions. You must use in-network providers or pay more (PPO) or pay everything (HMO). Rural areas and markets with fewer insurer options have thinner networks.
Prior authorization. Plans can require pre-approval for surgeries, imaging, specialist visits, and certain drugs. This can cause delays.
Plan instability. Medicare Advantage plans can change benefits, raise costs, or exit your market each year. You have to re-evaluate your plan during Annual Enrollment (October 15 to December 7) every year.
Medigap locked out. If you join Medicare Advantage and later want to switch to Original Medicare plus Medigap, insurers in most states can medically underwrite you and deny coverage. This is a significant risk if you develop serious health problems.
Service area limits. Emergency coverage applies anywhere, but routine care is tied to your plan's service area. Frequent travelers or snowbirds who spend months in a second location may face coverage gaps.
Prior authorization denials. Studies by the HHS Office of Inspector General found that Medicare Advantage plans denied a significant portion of requests that would have been covered by Original Medicare. Denials can be appealed, but that takes time and energy.
Which Is Better for Your Situation?
There is no universal answer. These scenarios describe who typically does better with each option.
Choose Original Medicare if you:
- Have doctors or specialists you cannot afford to lose
- Travel extensively or spend significant time in multiple states
- Have complex or chronic health conditions requiring frequent specialist visits
- Want predictable costs and can afford a Medigap policy
- Live in a rural area with few Medicare Advantage networks
- Are in excellent health and want maximum flexibility as a hedge
Choose Medicare Advantage if you:
- Are relatively healthy and price-sensitive
- Want dental, vision, and hearing benefits without buying separate coverage
- Live in an urban area with robust plan networks
- Prefer a single plan that handles most of your healthcare
- Can tolerate some unpredictability in annual plan changes
- Want an out-of-pocket cap without paying Medigap premiums
Medicare Savings Programs: Reducing Your Costs
If your income and assets are limited, you may qualify for Medicare Savings Programs that cover your Part B premium, deductibles, and coinsurance, regardless of which Medicare path you choose. These programs are funded by Medicaid and are often underutilized.
In 2026, the income limits for Medicare Savings Programs vary by state but generally fall in the range of $1,200 to $1,700 per month for a single person. Many people who qualify do not know these programs exist.

How to Switch Between Original Medicare and Medicare Advantage
Switching from Original Medicare to Medicare Advantage: You can do this during the Annual Enrollment Period (October 15 to December 7) or during your Initial Enrollment Period when you first become eligible.
Switching from Medicare Advantage back to Original Medicare: You can do this during the Annual Enrollment Period or during the Medicare Advantage Open Enrollment Period (January 1 to March 31). The key risk: once you switch back to Original Medicare, Medigap insurers can deny you coverage based on health history in most states.
Initial Enrollment Period: Runs from 3 months before your 65th birthday through 3 months after the month you turn 65, a 7-month window total.
Frequently Asked Questions
Which is cheaper, Original Medicare or Medicare Advantage?
Medicare Advantage usually has lower upfront monthly premiums. Many plans charge $0 beyond your Part B payment. But total costs depend on how much healthcare you use. If you are healthy, Medicare Advantage is often less expensive. If you develop a serious condition and hit high copays, or if your plan denies prior authorization for a needed service, costs can rise quickly. Original Medicare with a Medigap policy has higher monthly premiums but more predictable total costs.
Can I have both Medicare Advantage and a Medigap policy?
No. You cannot use a Medigap policy to cover gaps in a Medicare Advantage plan. Medigap only works alongside Original Medicare. If you enroll in Medicare Advantage, your Medigap coverage is redundant and you should not pay for it.
What happens if I move or travel with Medicare Advantage?
Emergency care is covered anywhere in the US, even outside your plan's network. But routine and non-emergency care is generally only covered within your plan's service area. If you spend several months per year in another state, a Medicare Advantage HMO plan will leave you with limited non-emergency coverage outside your home area. Original Medicare or a Medicare Advantage PPO with broader coverage handles this situation better.
Is the $0 premium Medicare Advantage plan actually free?
Not entirely. You still pay your Part B premium ($202.90 per month in 2026 at the standard rate). The "$0 premium" means the plan itself charges nothing on top of that. You also pay copays and coinsurance when you use services. Out-of-pocket costs add up depending on how much care you need.
Can I switch from Medicare Advantage back to Original Medicare?
Yes, but timing matters. You can switch during the Annual Enrollment Period (October 15 to December 7) or the Medicare Advantage Open Enrollment Period (January 1 to March 31). The challenge is Medigap: in most states, after your initial open enrollment window at 65, Medigap insurers can medically underwrite and deny you. If you are sick when you try to switch back, you may not qualify for Medigap and face unlimited out-of-pocket exposure under Original Medicare.
What are the income limits for help paying Medicare costs?
If your income is at or near the federal poverty level, you may qualify for programs that pay your Part B premium, reduce your drug costs through Extra Help (Low Income Subsidy), or cover deductibles and copays through Medicare Savings Programs. Income limits vary by state and household size, but even people with moderate incomes sometimes qualify. Use the CoveredUSA screener to check in 2 minutes.
Does Medicare Advantage cover dental and vision?
Almost all Medicare Advantage plans (98%+ in 2026) include some dental and vision benefits. Coverage varies, so review what each plan actually covers. Original Medicare does not cover routine dental or vision at all. If dental and vision are priorities, Medicare Advantage or a standalone supplement is your only path.
What is prior authorization and why does it matter?
Prior authorization means your Medicare Advantage plan must pre-approve certain services before you receive them. This can apply to specialist visits, imaging tests, surgeries, and some medications. Requests can be denied, requiring an appeal. Original Medicare rarely requires prior authorization. For people with complex health conditions who need frequent specialist care, the prior authorization burden of Medicare Advantage can be a significant drawback.
