20 Common Medicare FAQs
What is Medicare?
Medicare is a federal health insurance program created in 1965 to help older Americans and some younger people with certain disabilities get affordable healthcare.
It mainly serves:
- People age 65 and older
- People under 65 with certain disabilities (like ALS or long-term disability from Social Security)
- People with End-Stage Renal Disease (permanent kidney failure requiring dialysis or transplant)
Medicare helps cover hospital stays, doctor visits, preventive care, prescription drugs, and more — but it doesn’t cover everything, which is why some people get extra coverage.
When should I sign up for Medicare?
Most people should sign up during their Initial Enrollment Period (IEP), which lasts 7 months:
- Starts 3 months before your 65th birthday
- Includes your birthday month
- Ends 3 months after your birthday month
If you’re already getting Social Security benefits when you turn 65, you’ll usually be enrolled automatically in Parts A & B. If not, you’ll need to sign up through the Social Security Administration.
Tip: Missing this window can mean late enrollment penalties that last a lifetime!
What happens if I miss my enrollment window?
If you don’t enroll in Parts A, B, or D during your IEP, you might face:
Late penalties — For example, the Part B penalty is an extra 10% for each full 12-month period you were eligible but didn’t sign up. This penalty lasts for as long as you have Medicare!
Coverage gaps — You may have to wait until the General Enrollment Period (Jan 1–Mar 31) to sign up, and your coverage won’t start until July.
Exceptions — Some people qualify for a Special Enrollment Period (SEP) if they have other credible coverage, like through an employer or union.
What does Medicare Part A cover?
Think of Part A as your hospital insurance. It helps cover:
- Inpatient hospital stays (like surgeries and overnight stays)
- Skilled nursing facility care (after a qualifying hospital stay)
- Hospice care for terminally ill patients
- Limited home health services (like part-time skilled nursing care)
- Most people don’t pay a monthly premium for Part A if they or their spouse paid Medicare taxes for at least 10 years.
What does Medicare Part B cover?
Part B is your medical insurance, covering routine and outpatient care, such as:
- Doctor visits and specialist visits
- Preventive services (like flu shots, mammograms, colonoscopies)
- Outpatient services (like X-rays, lab work)
- Durable medical equipment (like wheelchairs and walkers)
- Certain home health services
You pay a monthly premium for Part B, and there’s usually an annual deductible. After you meet the deductible, you typically pay 20% coinsurance for covered services.
What is Medicare Advantage (Part C)?
Medicare Advantage plans are offered by private insurance companies approved by Medicare.
When you choose a Part C plan, you’re still in Medicare — but you get your Parts A and B through the plan instead of Original Medicare.
Most Advantage plans also include Part D (drug coverage) plus extra benefits Original Medicare doesn’t cover, like dental, vision, hearing, or fitness programs.
Important: With Medicare Advantage, you usually need to use the plan’s network of doctors and hospitals to get the lowest costs.
What does Medicare Part D cover?
Part D helps pay for prescription medications. You can get it through:
- A stand-alone Part D Prescription Drug Plan if you have Original Medicare
- Or a Medicare Advantage Plan that includes drug coverage
Part D plans vary by insurance company, but they all have a formulary — the list of covered drugs. It’s smart to check that your prescriptions are covered before you choose a plan.
Do I need Part B if I’m still working?
It depends! If you have health insurance through your (or your spouse’s) active employment:
- You may be able to delay enrolling in Part B without penalty.
- Always check with your employer’s HR or benefits office to confirm whether your plan is creditable coverage for Medicare.
Tip: COBRA and retiree coverage don’t count as active employer coverage, so different rules apply!
What is Medigap (Medicare Supplement Insurance)?
Original Medicare (Parts A & B) covers a lot but not everything — you still pay deductibles, coinsurance, and copayments.
Medigap is optional supplemental insurance sold by private companies that helps cover these “gaps.”
- Medigap works only with Original Medicare, not with Medicare Advantage.
- There are different standardized Medigap plans (Plan A, Plan G, Plan N, etc.), each with different coverage levels.
What does “premium-free Part A” mean?
If you worked and paid Medicare taxes for at least 40 quarters (10 years), you likely qualify for premium-free Part A.
If you don’t qualify, you can still buy Part A, but you’ll pay a monthly premium.
How much does Part B cost?
The standard Part B premium is set each year by the federal government. In 2024, it’s about $174.70 per month for most people.
However, if you have a higher income, you may pay more due to an Income-Related Monthly Adjustment Amount (IRMAA).
You’ll also have an annual deductible for Part B ($240 in 2024) and pay 20% coinsurance for covered services.
Does Medicare cover dental, vision, or hearing?
Original Medicare generally does not cover:
- Routine dental care (like cleanings or dentures)
- Eye exams for prescription glasses
- Hearing aids or routine hearing exams
However, many Medicare Advantage plans include these extra benefits. If you stick with Original Medicare, you may need separate dental or vision insurance.
Can I keep my doctor with Medicare?
Yes — as long as your doctor accepts Medicare assignment, which means they agree to Medicare’s approved payment amount.
With Medicare Advantage plans, you’ll need to check if your doctors and hospitals are in the plan’s network — otherwise, you may pay more or have no coverage for out-of-network providers.
What’s the difference between Original Medicare and Medicare Advantage?
Original Medicare is the traditional program run by the government (Parts A & B). You can add a stand-alone Part D plan and Medigap if you want.
Medicare Advantage (Part C) is an all-in-one plan from a private insurer that covers everything Original Medicare does, plus often extra benefits — but you’ll usually need to use a network.
How do I get help paying for Medicare?
If you have limited income and resources, programs like:
- Medicare Savings Programs (MSPs) — can help pay Part A & B premiums, deductibles, and coinsurance.
- Extra Help — helps with prescription drug costs under Part D.
Medicaid — a joint federal and state program that helps with medical costs for some people with limited income.
How do I pay my Medicare premiums?
Most people have their Part B premium taken automatically from their Social Security check each month.
If you don’t get Social Security, you can pay by:
- Bank draft (online or recurring)
- Mailing a check or money order
Paying by credit or debit card through your Medicare account
What’s a deductible?
A deductible is the amount you pay for healthcare services before Medicare or your plan starts to pay. For example, you pay the Part B deductible each year before Medicare covers your doctor visits and tests.
What’s coinsurance?
Coinsurance is your share of costs for a service after you meet your deductible.
Example: After you meet your Part B deductible, you typically pay 20% coinsurance for approved services.
Can I change my plan later?
Yes! Every year, you can:
- Switch plans during the Annual Enrollment Period (Oct 15 – Dec 7) for Medicare Advantage or Part D.
If you qualify for a Special Enrollment Period (SEP) — like moving, losing other coverage, or your plan’s contract changing.
