Medicare works well for some people and poorly for others — it depends on your health, your income, and what you're willing to pay out of pocket

Medicare is not one thing. It's four separate programs (Parts A, B, C, and D), and whether it's "good" for you depends on which parts you use, what they cover, and what you can afford to pay. Part A covers hospital stays. Part B covers doctor visits and outpatient care. Part C (Medicare Advantage) is an alternative to A and B run by private insurers. Part D covers prescription drugs. Some people find Medicare covers what they need at a price they can manage. Others face high deductibles, gaps in coverage, or drugs that aren't covered at all.

Key Takeaways

  • Medicare Part A covers hospital care but has a deductible of $1,676 per hospital stay in 2024, and you pay coinsurance after 60 days.
  • Part B covers doctor visits and tests but requires a monthly premium (around $175 in 2024) plus a $240 annual deductible and 20% coinsurance.
  • Part D (prescription drug coverage) has a coverage gap called the "donut hole" where you pay the full cost of drugs between $5,850 and $8,550 in annual spending.
  • Medicare Advantage (Part C) often has lower premiums and out-of-pocket caps but may limit which doctors and hospitals you can use.
  • Supplemental insurance (Medigap) can cover Medicare's gaps but costs extra and is not the same as Medicare Advantage.

What Medicare Part A and Part B Actually Pay For

Part A covers inpatient hospital stays, skilled nursing facility care after a hospital stay, hospice, and some home health care. You pay a deductible ($1,676 in 2024) for each hospital stay, and after 60 days in the hospital you pay coinsurance — the amount increases the longer you stay. Part A is free if you or your spouse paid Medicare taxes for at least 10 years.

Part B covers doctor visits, outpatient surgery, tests, and preventive care like screenings and vaccines. You pay a monthly premium (around $175 in 2024, though it's higher if your income is above a certain threshold), a $240 annual deductible, and then 20% of the cost of most services after the deductible is met. Part B does not cover routine dental, vision, or hearing care — those are separate expenses.

Neither Part A nor Part B covers long-term care in a nursing home or assisted living, which is one of the largest gaps many people discover too late. They also do not cover most prescription drugs, which is why Part D exists.

The Real Cost of Part D and the Coverage Gap

Part D covers prescription drugs through private insurance plans you choose. Each plan has a different list of covered drugs, a monthly premium, an annual deductible (usually $100 to $500), and a copay or coinsurance for each drug. The problem is the coverage gap, sometimes called the "donut hole."

In 2024, once you and your plan have paid $5,850 in drug costs combined, you enter the gap and pay the full price of your drugs until your out-of-pocket spending reaches $8,550. After that, catastrophic coverage kicks in and you pay only a small copay. For someone taking multiple expensive medications, the gap can mean thousands of dollars in a single year. The gap shrinks slightly each year by law, but it has not disappeared.

You can avoid some gap costs by choosing a plan with better coverage for your specific drugs, but that requires knowing your drugs in advance and comparing plans carefully each year — plans change their drug lists annually.

Medicare Advantage (Part C) vs. Original Medicare

Medicare Advantage is an alternative to Parts A and B offered by private insurers like UnitedHealthcare, Humana, and Aetna. The appeal is often a lower or zero monthly premium and a yearly out-of-pocket spending cap — once you hit that cap (usually $7,000 to $10,000), the plan pays 100% of covered services for the rest of the year.

The trade-off is that Medicare Advantage plans often have smaller networks of doctors and hospitals, higher copays per visit, and may require referrals to see specialists. Some plans cover dental, vision, or hearing — benefits original Medicare does not — but the coverage is usually limited. If you travel frequently or live part of the year in another state, a Medicare Advantage plan may not work well because you may not have coverage outside the plan's service area.

Medicare Advantage plans can also change their networks and drug coverage each year, so a doctor you see this year may not be in-network next year. You have a 45-day window each year (January 1 to February 14) to switch plans if that happens.

Supplemental Insurance (Medigap) and What It Covers

Medigap is supplemental insurance sold by private insurers that covers some of the costs Medicare does not — deductibles, coinsurance, and copays. It is not the same as Medicare Advantage. You use Medigap alongside original Medicare (Parts A, B, and D), not instead of it.

There are ten standardized Medigap plans (labeled A through N), and each covers a different combination of gaps. Plan G, for example, covers the Part B deductible, coinsurance, and copays. Plan N covers most of the same things but charges a copay for doctor visits and emergency room visits. The monthly premium for Medigap varies by age, location, and which plan you choose — it can range from $100 to $400 or more per month.

Medigap is most valuable if you use a lot of medical care or have chronic conditions, because it limits your out-of-pocket costs. If you are healthy and rarely see a doctor, the monthly premium may cost more than you would spend on deductibles and coinsurance anyway.

Who Finds Medicare Works Well

Medicare works best for people with predictable, moderate healthcare needs and stable income. If you see your doctor a few times a year, take one or two common medications, and do not need hospitalization, original Medicare with a Medigap plan can be affordable and straightforward. You can see any doctor who accepts Medicare, and you know what you will pay.

It also works well for people with very high healthcare costs — those with chronic illnesses, multiple medications, or frequent hospitalizations — because Medigap plans cap your out-of-pocket spending and cover most gaps. The monthly premium is worth it when you are spending thousands on medical care anyway.

Medicare Advantage can work well for people who are healthy, do not mind using a smaller network of doctors, and want dental or vision coverage included. The lower premiums and out-of-pocket caps appeal to people on tight budgets.

Who Struggles With Medicare

Medicare is harder to afford for people with modest incomes who do not may have access to for help paying premiums and deductibles. If you earn just above the threshold for Medicaid or low-income subsidies, you may pay full price for Parts B and D, plus a Medigap premium, which can easily exceed $400 to $500 per month.

People with rare or expensive medications often struggle because Part D plans may not cover their drugs, or the coverage gap makes them unaffordable. Those with complex medical needs may find Medicare Advantage networks too restrictive or discover that their preferred specialist is not in-network.

People who need long-term care — nursing home or assisted living — find Medicare covers almost none of it. They must pay out of pocket, use Medicaid (which requires spending down assets first), or rely on family. This is one of the largest financial risks Medicare does not address.

How to Know If Medicare Is Right for Your Situation

Start by listing your current doctors, medications, and how often you use healthcare. Then compare original Medicare with a Medigap plan against Medicare Advantage plans available in your area. Medicare.gov has a plan comparison tool where you can enter your drugs and see which plans cover them and at what cost.

If you have low income, ask about the Extra Help program (for Part D) or Medicaid, which can pay your premiums and reduce your out-of-pocket costs. Your State Health Insurance information Program (SHIP) offers free counseling to help you compare plans — the phone number is on Medicare.gov.

Remember that you can change plans once a year during the annual enrollment period (October 15 to December 7). If your situation changes — you move, your health worsens, or a doctor leaves your plan's network — you may have a special enrollment period to switch outside the annual window.

Frequently Asked Questions

Does Medicare cover dental, vision, or hearing?

Original Medicare does not cover routine dental, vision, or hearing care. Some Medicare Advantage plans include these benefits, but coverage is usually limited — for example, one eye exam per year or one hearing aid fitting. You can also buy standalone dental or vision insurance, though it is often expensive and has waiting periods.

What happens if I can't afford my Medicare premiums?

If your income is low, you may may have access to for Medicaid, which can pay your Medicare premiums and reduce your out-of-pocket costs. You can also ask about the Part D Extra Help program if you cannot afford prescription drug coverage. Your state Medicaid office or SHIP can tell you whether you may have access to.

Can I use Medicare if I move to another state?

Yes, original Medicare works in all 50 states and U.S. territories. Medicare Advantage plans are tied to specific service areas, so if you move, you will need to switch to a plan available in your new location. You have a special enrollment period to change plans when you move.

What if my doctor stops accepting Medicare?

If you use original Medicare, you can see any Medicare-accepting doctor. If your doctor stops accepting Medicare, you can find another doctor or ask your current doctor to refer you. If you use Medicare Advantage and your doctor leaves the network, you can switch to a different Medicare Advantage plan during the annual enrollment period or a special enrollment period.

Is Medicare Advantage cheaper than original Medicare with Medigap?

It depends on your health and how much care you use. Medicare Advantage usually has a lower or zero monthly premium, but higher copays per visit. Original Medicare with Medigap has a higher monthly premium but lower copays and more predictable costs. If you are healthy, Advantage is often cheaper. If you use a lot of care, Medigap is often cheaper overall.
