Do you legally have to apply for Medicare at 65?

Editorial team Published on

No, signing up for Medicare at age 65 is not strictly mandatory, but failing to enroll on time can lead to lifelong late penalties and coverage gaps unless you qualify to delay.

📌 Key Enrollment Scenarios

  • ✅ Already collecting Social Security:
    • Enrolled automatically in Parts A and B.
    • No action needed.
  • ✅ Working with large employer coverage (20+ employees):
    • Can safely delay Part B without penalty.
    • Can take premium-free Part A (unless contributing to an HSA).
  • ⚠️ Working with small employer coverage (under 20 employees):
    • Must enroll in Parts A and B.
    • Medicare acts as primary insurance.
  • ⚠️ Retiree coverage or COBRA:
    • Must enroll at age 65.
    • Not considered active current employer coverage.

💡 Financial Risks of Delaying

  • Part B Penalty: 10% premium increase for each 12-month period delayed.
  • Duration: Penalty lasts for as long as you have Part B.
  • HSA Conflict: Must stop Health Savings Account contributions 6 months prior to enrollment.

What happens if I do not enroll in Medicare at 65?

If you do not enroll in Medicare when you turn 65, you may face lifelong monthly premium penalties and gaps in health coverage, unless you qualify for an exemption by having qualifying employer-sponsored health insurance.

Late Enrollment Penalties

  • Part B Penalty: Your monthly premium increases by 10% for every full 12-month period you delayed signing up without qualifying coverage. You pay this extra cost for as long as you have Part B.
  • Part D Penalty: Your monthly prescription drug premium increases by 1% of the national base beneficiary premium for every month you went without creditable drug coverage. This penalty is added to your bill for life.
  • Part A Penalty: If you have to buy Part A (instead of getting it premium-free), your monthly premium goes up 10% and you pay it for twice the number of years you delayed.

Coverage Gaps

  • If you miss your initial window and do not qualify for a Special Enrollment Period, you must wait for the General Enrollment Period (January 1 through March 31) to sign up, meaning your coverage will not start until July 1, leaving you uninsured.

When You Can Delay Without Penalty

  • Active Employer Coverage: You can delay enrollment penalty-free if you or your spouse are actively working and you are covered by that employer's group health plan (usually with 20 or more employees).
  • Special Enrollment Period: Once that active employment or group coverage ends, you get an 8-month window to sign up for Part B without a penalty.

How much will Medicare cost me once I turn 65?

When you turn 65, your minimum standard cost for Medicare will be $202.90 per month. However, Medicare is not entirely free, and your final out-of-pocket costs will depend on your work history, your income, and the supplemental plans you choose.

An overview of what you will pay based on the official Centers for Medicare & Medicaid Services (CMS) rates outlines the primary costs:

1. The Core Components (Original Medicare)

  • Part A (Hospital Insurance): $0 per month for most people. If you or your spouse worked and paid Medicare taxes for at least 10 years (40 quarters), you do not pay a premium. If you use it, there is a $1,736 deductible per hospital benefit period.
  • Part B (Medical/Outpatient Insurance): $202.90 per month (standard premium). This is required for anyone on Medicare. There is also an annual $283 deductible, after which you typically pay 20% of your doctor visits and outpatient care costs.

2. High-Income Adjustments (IRMAA)

If your modified adjusted gross income from two years ago (tracked via your tax returns) was higher than $109,000 for a single filer or $218,000 for a married couple filing jointly, you will pay an extra surcharge known as IRMAA. Your total Part B premium could range from $284.10 to $689.90 per month depending on your exact bracket.

3. Essential Add-Ons (What Most People Actually Choose)

Because Original Medicare has no maximum out-of-pocket limit, most 65-year-olds choose one of two pathways to control their healthcare expenses:

Path OptionsEstimated Monthly CostWhat You Get
The Supplemental Route
(Original Medicare + Medigap + Part D)
$388 – $458 / month• Part B: $202.90
• Part D (Drugs): ~$35 average premium
• Medigap (e.g., Plan G): ~$150–$220 (covers your 20% co-insurance and deductibles).
The Medicare Advantage Route
(Part C)
$203 – $250 / month• Part B: $202.90
• Part C Plan Premium: Often $0 or a very low monthly fee. Combines medical, hospital, and drugs into one network-based plan with a set annual out-of-pocket maximum.

Note: If you plan to enroll in 2027, the standard Part B premium is projected to increase slightly to $209.50 per month and the annual Part D drug out-of-pocket limit will rise to $2,400. Final rates for 2027 will be finalized by CMS in late fall.

Can I refuse to enroll in Medicare?

Yes, you can refuse or delay Medicare enrollment, but the rules and penalties depend entirely on whether you already collect Social Security and whether you have other health coverage.

✅ If You Are Turning 65 and Not Collecting Social Security

  • Action: You can simply choose not to sign up for Original Medicare when you turn 65.
  • Penalty Risk: You will face lifetime late penalties later unless you have active, creditable employer coverage (from a company with 20+ employees).
  • HSA Exception: Delaying Part A and B allows you to keep contributing to a Health Savings Account (HSA) tax-free.

⚠️ If You Already Collect Social Security or Railroad Retirement

  • Action: You are automatically enrolled in Parts A and B, and opting out requires signing official paperwork and returning your Medicare card.
  • Hidden Cost: You must withdraw from Social Security entirely and repay all benefits you have already received to refuse premium-free Part A.
  • Alternative: You can drop just Part B by following the instructions that come with your card, but you keep Part A.

Which Medicare plan is free at age 65?

Medicare Part A (Hospital Insurance) is free (has a $0 monthly premium) for most people when they turn 65.

How to Qualify for Free Part A

You get premium-free Part A if you or your spouse paid Medicare taxes while working for at least 10 years (or 40 work quarters).

What Isn't Free

While Part A is premium-free for eligible workers, other parts of Medicare require monthly payments and out-of-pocket costs:

  • Part B (Medical Insurance): Covers doctor visits and outpatient care, but requires a standard monthly premium.
  • Part C (Medicare Advantage) & Part D (Prescription Drugs): Offered by private companies and usually charge separate monthly premiums.
  • Deductibles & Copays: Even with free Part A, you still pay deductibles (such as the hospital inpatient deductible) when you receive care.

9 related questions found

What is the big mistake people make with Medicare?

The single biggest and most costly mistake people make with Medicare is missing enrollment deadlines, leading to permanent late-enrollment penalties and gaps in coverage.

Missing Enrollment Deadlines

  • Initial Enrollment Period (IEP): This window lasts for seven months. It starts three months before the month you turn 65, includes your birthday month, and ends three months after.
  • Late Penalties: Failing to sign up for Part B or Part D on time can trigger permanent monthly or yearly financial penalties added to your premiums.
  • Delayed Enrollment Confusion: Many people wrongly assume they can delay Medicare past age 65 just because they have health coverage like COBRA, a marketplace plan, or small-employer insurance.

Other Costly Medicare Mistakes

  • Ignoring Annual Changes: Sticking with automatic renewal without reading the Annual Notice of Change (ANOC) can result in unexpected costs, as drug lists and doctor networks shift every year.
  • Choosing Solely by Low Premiums: Picking a plan based only on a low monthly cost while ignoring total out-of-pocket expenses like deductibles, copays, and coinsurance.
  • Missing the Medigap Window: Forgetting to apply for a Medigap (Medicare Supplement) policy during your open enrollment window. After this six-month period, insurers can use medical underwriting to charge more or deny coverage.
  • Skipping Financial Assistance: Overlooking programs like Medicare Savings Programs or Part D Extra Help that assist with out-of-pocket medical and prescription expenses.

Can I have both Social Security and Medicare?

Yes, you can receive both Social Security and Medicare at the same time.

How They Work Together

  • Separate Programs: Social Security provides monthly cash income for retirement or disability, while Medicare provides federal health insurance.
  • Simultaneous Receipt: Most eligible people aged 65 or older (or those with qualifying disabilities) get both programs at the same time.
  • Automatic Enrollment: If you are already collecting Social Security benefits when you turn 65, you are automatically enrolled in Medicare Parts A and B.
  • Premium Deductions: If you receive Social Security benefits when you enroll in Medicare, your Medicare Part B (medical insurance) premiums are usually deducted directly from your monthly Social Security check.

Key Rules

  • Different Age Triggers: You can claim early Social Security retirement benefits starting at age 62, but standard Medicare eligibility does not begin until age 65 (unless you qualify early due to a disability).
  • Independent Choices: You can delay taking Social Security benefits past age 65 while still signing up for Medicare at age 65, though you will have to pay your Medicare premiums directly rather than through a deduction. You can visit the Social Security Administration to manage your options.

Can someone who never worked get Medicare at 65?

Yes, you can get Medicare at age 65 even if you have never worked or paid Medicare taxes, provided you are a U.S. citizen or a permanent legal resident who has lived in the U.S. for at least five continuous years.

While work history does not block your eligibility, it does affect how much you pay for your coverage.

How Coverage and Costs Work

  • Medicare Part A (Hospital Insurance): Usually premium-free for people who worked at least 10 years (40 quarters). If you have no work history, you can still get Part A by paying a monthly premium.
  • Qualifying Through a Spouse: You can get premium-free Part A if you are married to someone who has enough work credits, as detailed by GoHealth. This also applies if you are a divorced or widowed spouse meeting specific marriage-length requirements (such as being married for 10 years before a divorce).
  • Medicare Part B (Medical Insurance): Part B costs are the same regardless of your personal work history. You pay the standard monthly premium to enroll.
  • Financial Assistance: If you cannot afford the Part A or Part B premiums, state programs like Medicaid or Medicare Savings Programs may help cover the costs.

You can learn more about enrollment rules directly through the Official Medicare Site.

Why am I paying $700 a month for Medicare?

You are likely paying close to $700 a month because of an income-based surcharge called IRMAA (Income-Related Monthly Adjustment Amount) added to your Social Security Administration Benefits Planner.

Why the Cost is High

  • The IRMAA Surcharge: While the standard Medicare Part B monthly premium is $202.90, higher earners must pay an extra surcharge. If your total monthly cost reaches nearly $700, your past income has pushed you into a higher IRMAA bracket.
  • Look-Back Period: Medicare determines IRMAA using your Modified Adjusted Gross Income (MAGI) from two years prior. A high-income tax return from two years ago dictates your current monthly bill.
  • Combined Parts: This total often includes surcharges for both Part B (outpatient care) and Part D (prescription drug coverage).
  • Automatic Deduction: This amount is typically taken directly out of your monthly Social Security check or billed quarterly if you are not yet collecting benefits.

What You Can Do

  • Check for Life-Changing Events: If you experienced a major income drop due to a life-changing event (such as marriage, divorce, or work reduction), you can appeal to have your surcharge lowered.
  • Review Details: You can check specific rules and thresholds directly through AARP's Medicare Guide or contact Social Security.

What are the four things Medicare doesn't cover?

Original Medicare does not cover four major categories of health needs: routine dental care, eyeglasses and routine eye exams, hearing aids and exams, and long-term (custodial) care.

Key Uncovered Services

  • Routine Dental Care: Original Medicare excludes cleanings, fillings, tooth extractions, root canals, and dentures. It only covers very limited, specific procedures tied to another medical treatment (such as a dental exam before certain organ transplants or jaw reconstruction).
  • Vision Care: Routine eye exams, eyeglasses, and contact lenses are not covered. Medicare does cover medically necessary treatments for specific eye diseases like cataracts or glaucoma, but not the glasses needed afterward.
  • Hearing Care: Routine hearing tests, hearing aid fittings, and hearing aids themselves are excluded from Original Medicare. Diagnostic exams are covered only if ordered by a physician to evaluate a medical problem.
  • Long-Term Care: Custodial care—such as help with daily activities like bathing, dressing, eating, or using the bathroom—is not covered when it is the main kind of care you need. Medicare Part A only covers short-term skilled nursing care after a qualifying hospital stay.

Other common exclusions include care received outside the United States, cosmetic surgery, and routine foot care. You can find comprehensive details on Original Medicare Coverage Exclusions directly from Medicare.gov.
