Medicare Basics

What Is Medicare?

Medicare is the federal health insurance program for Americans 65 and older, as well as certain younger people with disabilities or specific medical conditions. Understanding how it’s structured helps you make smarter enrollment decisions.

A federal program protecting millions of Americans

Created in 1965, Medicare is administered by the Centers for Medicare & Medicaid Services (CMS). It covers hospital stays, doctor visits, prescription drugs, and much more — split across four distinct parts, each with its own rules, costs, and enrollment windows.

The Four Parts of Medicare Explained
Part A — Hospital Insurance
Inpatient & Facility Coverage

Part A covers care you receive inside a hospital or facility. For most people who worked and paid Medicare taxes for at least 10 years, Part A has no monthly premium.

  • Inpatient hospital stays
  • Skilled nursing facility care
  • Hospice and palliative care
  • Home health services
$0/mo (40+ qtrs) · $1,632 deductible per benefit period
Part B — Medical Insurance
Outpatient & Preventive Coverage

Part B covers medical services and supplies needed to diagnose or treat a condition. It also includes a wide range of preventive screenings and wellness visits at no cost to you.

  • Doctor and specialist visits
  • Outpatient procedures and surgery
  • Preventive screenings & vaccines
  • Durable medical equipment
$202.90/mo standard (2026) · $257 annual deductible
Part C — Medicare Advantage
All-in-One Private Plan

Medicare Advantage is an alternative to Original Medicare. These plans are offered by CMS-approved private insurers and often bundle extra benefits not available in Original Medicare.

  • Includes all Part A & B benefits
  • Often includes Part D drug coverage
  • May add dental, vision & hearing
  • Plan networks vary by location
Avg. ~$17/mo (2026) · replaces Parts A & B
Part D — Prescription Drugs
Outpatient Drug Coverage

Part D adds prescription drug coverage to Original Medicare. You choose a plan from a private insurer — each plan has its own formulary and cost structure.

  • Covers most FDA-approved prescription drugs
  • Tiered copay structure by drug type
  • $2,000 annual out-of-pocket cap (2025+)
  • Late penalty if you delay without coverage
Avg. $46.50/mo (2026) · IRMAA surcharge for higher earners
Step-by-Step Guide

How to Use the Medicare Eligibility Calculator

Our free calculator walks you through six simple steps. Here’s exactly what to expect at each stage — and what information to have ready before you begin.

1
Step 1
Choose Your Eligibility Path

Start by selecting how you qualify for Medicare. Most people choose the standard Age 65+ path. If you receive Social Security Disability Insurance (SSDI), select the Disability path. If you have End-Stage Renal Disease or ALS, select ESRD / ALS — each follows different rules and timelines.

Age 65+ (standard)
Disability / SSDI
ESRD / ALS
Tip: The SSDI path applies only if you’ve been receiving disability payments for at least 24 months.
2
Step 2
Enter Your Personal Information

Provide your date of birth, state of residence, employment status, and how many years you’ve paid Medicare taxes. Your date of birth is the most critical input — it’s used to calculate your exact Initial Enrollment Period (IEP) window down to the month.

Date of birth
State of residence
Employment status
Work quarters
Late Penalty Estimator: If you’ve already passed your eligibility date without enrolling, enter the months delayed to see your estimated permanent premium increase.
3
Step 3
Select Your Medicare Coverage Parts

Choose which Medicare parts you’re interested in — you can select one or all four. Each card shows the standard 2026 premium so you can immediately gauge cost. Note: selecting Part C (Medicare Advantage) replaces Parts A & B in your cost total.

Part A — Hospital
Part B — Medical
Part C — Advantage
Part D — Drugs
Tip: You can’t have both Part C and Original Medicare (Parts A & B) simultaneously. If you select Part C, Parts A and B premiums are excluded from your total.
4
Step 4
Enter Your Income & Tax Filing Status

Medicare uses your Modified Adjusted Gross Income (MAGI) from two years prior to determine whether you owe an IRMAA surcharge on Parts B and D. Select your 2024 filing status and income bracket — the calculator instantly shows your bracket and exact 2026 premium.

2024 tax filing status
2024 MAGI income bracket
Live IRMAA bracket table
Two-year lookback: Your 2026 premiums are based on 2024 tax data. If your income has dropped due to retirement or a life event, you can appeal with Form SSA-44.
5
Step 5
Set Your Expected Healthcare Usage

Use four sliders to describe how often you expect to use healthcare services. This estimates your out-of-pocket costs on top of your premiums — the more accurately you fill this in, the more realistic your monthly total will be.

Doctor visits / year
Rx medications / month
Hospital stays / year
Specialist visits / year
Tip: Think about your average usage from the past 1–2 years. Even rough estimates give you a useful cost range to plan around.

Who Qualifies

Medicare Eligibility Requirements

Medicare eligibility depends on your age, work history, citizenship status, and health conditions. Most Americans qualify automatically at 65 — but there are several other pathways. Review the requirements below to understand which apply to you.

Do you meet the basic requirements?

Most Americans need to satisfy at least one of three conditions: reach age 65, have a qualifying disability, or be diagnosed with ESRD or ALS. Work history and citizenship status also play a role in your premium costs.

Age 65+
SSDI 24+ months
ESRD or ALS
Eligibility Pathways
Most Common Pathway
Age-Based Eligibility — Turning 65

The standard route to Medicare. You become eligible on the first day of the month you turn 65. Your Initial Enrollment Period (IEP) opens 3 months before your birthday and closes 3 months after — giving you a 7-month window to enroll without penalty.

  • Must be age 65 or turning 65
  • Must be a U.S. citizen or qualifying permanent resident (5+ years)
  • Must be enrolled in or eligible for Social Security or Railroad Retirement benefits
  • 7-month Initial Enrollment Period (3 months before + birthday month + 3 months after)
If you already receive Social Security benefits, you’ll be enrolled in Parts A and B automatically — you don’t need to apply.
SSDI Pathway
Disability & SSDI Eligibility

If you’re under 65 and receive Social Security Disability Insurance (SSDI), you automatically qualify for Medicare after a 24-month waiting period.

  • Must be receiving SSDI payments
  • 24-month waiting period from first SSDI payment
  • Auto-enrolled in Parts A & B on month 25
  • No age minimum applies
The 24-month wait does not apply to people with ALS — they are enrolled automatically when SSDI begins.
Medical Condition Pathway
ESRD & ALS Eligibility

Individuals with End-Stage Renal Disease (permanent kidney failure requiring dialysis or transplant) or ALS can qualify for Medicare regardless of age or work history.

  • ESRD: eligible from the 4th month of regular dialysis
  • ESRD: eligible immediately after a successful kidney transplant
  • ALS: auto-enrolled in Medicare when SSDI begins — no wait
  • No age minimum for either condition
ESRD Medicare coverage can end 12 months after a successful transplant if you no longer require ongoing treatment.
Additional Requirements
Affects Part A Premium
Work History & Quarters

Your Part A premium — or lack thereof — is determined entirely by how many quarters (3-month periods) you or your spouse worked and paid Medicare payroll taxes.

40+ quarters — $0/mo Part A
30–39 quarters — $285/mo
Under 30 quarters — $518/mo
  • 40+ quarters (10 years) = premium-free Part A
  • 30–39 quarters = $285/mo Part A (2026)
  • Under 30 quarters = $518/mo Part A (2026)
  • Part B standard premium is $202.90/mo regardless of work history
Residency Requirement
Citizenship & Residency Rules

To enroll in Medicare, you must meet one of the following citizenship or lawful residency criteria. Non-citizens may still qualify under certain conditions.

  • U.S. citizen living in the United States
  • Lawful permanent resident (green card holder) for 5+ continuous years
  • Must reside in one of the 50 states, D.C., or certain U.S. territories
  • Non-residents living abroad are generally not eligible for Medicare coverage
U.S. citizens living abroad may enroll in Medicare but typically cannot use coverage outside the U.S. — with limited exceptions.
Derived Eligibility
Spouse & Dependent Eligibility

Even if you haven’t personally worked long enough to qualify for premium-free Part A, you may be eligible based on your spouse’s work record — including ex-spouses and deceased spouses.

  • Spouse with 40+ work quarters qualifies you for premium-free Part A
  • Divorced spouses (married 10+ years) may qualify based on ex-spouse’s record
  • Widows and widowers may qualify via deceased spouse’s work history
  • Qualifying spouse must be at least 62 years old
Part B eligibility for spouses is determined independently — each person must meet age, citizenship, and residency requirements on their own.
Missing your enrollment window has consequences. If you don’t enroll during your Initial Enrollment Period and don’t qualify for a Special Enrollment Period, you may face a permanent late enrollment penalty on your Part B and Part D premiums. Use the calculator above to find your exact enrollment dates.

Eligibility
1
Who is eligible for Medicare?
Most Americans become eligible for Medicare at age 65 if they are a U.S. citizen or lawful permanent resident who has lived in the U.S. for at least 5 consecutive years. You may also qualify before 65 if you have received Social Security Disability Insurance (SSDI) for 24 months, have End-Stage Renal Disease (ESRD), or have been diagnosed with ALS (Lou Gehrig's disease).
2
Can I get Medicare before age 65?
Yes. You can qualify for Medicare before 65 in three situations: (1) You have received SSDI benefits for at least 24 months; (2) You have been diagnosed with End-Stage Renal Disease and require dialysis or a transplant; or (3) You have ALS — in which case Medicare begins automatically the same month your SSDI starts, with no waiting period.
3
Do I need to have worked to qualify for Medicare?
Work history is not required to qualify for Medicare — but it directly affects your Part A premium. If you or your spouse have at least 40 work quarters (10 years) of Medicare-taxed employment, Part A is free. With 30–39 quarters the premium is $285/mo, and under 30 quarters it's $518/mo (2026 figures). Part B eligibility is the same regardless of work history.
4
Can I get Medicare based on my spouse's work record?
Yes. If you haven't worked enough quarters yourself, you may qualify for premium-free Part A based on your spouse's work record — provided your spouse has 40+ qualifying quarters. This also applies to divorced spouses (married 10+ years) and widows or widowers. Your qualifying spouse must be at least 62 years old.
5
What are the citizenship requirements for Medicare?
To enroll in Medicare you must be either a U.S. citizen or a lawful permanent resident (green card holder) who has resided continuously in the United States for at least 5 years. Non-residents living outside the U.S. are generally not eligible for Medicare coverage.
Enrollment
6
When can I first enroll in Medicare?
Your Initial Enrollment Period (IEP) is a 7-month window: it opens 3 months before the month you turn 65, includes your birthday month, and closes 3 months after. Enrolling in the first 3 months ensures your coverage starts on the 1st of your birthday month. If you enroll in month 4 or later, there may be a delay of 1–3 months before coverage begins.
Use the Medicare Eligibility Calculator above to find your exact IEP dates based on your date of birth.
7
What happens if I miss my Initial Enrollment Period?
If you miss your IEP without qualifying for a Special Enrollment Period, you can sign up during the General Enrollment Period (GEP) — January 1 to March 31 each year, with coverage starting July 1. You may also face a permanent late enrollment penalty: 10% added to your Part B premium for each full 12-month period you were eligible but didn't enroll.
The Part B late penalty is permanent — it doesn't go away once applied. Enroll on time to avoid it.
8
Can I delay Medicare enrollment if I still have employer coverage?
Yes. If you or your spouse are still actively working and covered by an employer group health plan, you can delay Part B enrollment without penalty. Once your employer coverage ends, you have an 8-month Special Enrollment Period (SEP) to sign up for Part B without facing a late penalty. COBRA and retiree coverage do not count as active employer coverage for this purpose.
9
Is Medicare enrollment mandatory?
No — Medicare enrollment is not legally required. However, delaying enrollment without qualifying creditable coverage means you could face permanent late penalties on your Part B and Part D premiums when you do enroll. For most people without employer coverage, enrolling during the IEP is the most cost-effective decision.
10
When is Medicare Open Enrollment for 2026 coverage?
Medicare's Annual Enrollment Period (AEP) — when you can switch Medicare Advantage or Part D plans — runs from October 15 to December 7 each year. Changes made during this period take effect January 1 of the following year. There is also a Medicare Advantage Open Enrollment Period from January 1 to March 31, during which Advantage plan enrollees can switch plans or return to Original Medicare once.
11
Will I be automatically enrolled in Medicare?
You will be automatically enrolled in Medicare Parts A and B if you are already receiving Social Security or Railroad Retirement Board benefits when you turn 65. You'll receive your Medicare card about 3 months before your 65th birthday. If you are not yet collecting Social Security, you must actively apply for Medicare — online at SSA.gov, by phone at 1-800-772-1213, or in person at a Social Security office.
Costs & Premiums
12
How much does Medicare cost per month in 2026?
In 2026, the standard costs are: Part A — $0/mo with 40+ work quarters; Part B — $202.90/mo standard premium; Part C (Advantage) — averaging around $17/mo; Part D — averaging $46.50/mo. Higher-income earners pay more via IRMAA surcharges on Parts B and D. The Part B deductible is $257 annually and the Part A deductible is $1,736 per benefit period in 2026.
13
What is IRMAA and how does it affect my Medicare premium?
IRMAA stands for Income-Related Monthly Adjustment Amount. If your Modified Adjusted Gross Income (MAGI) from 2 years ago exceeds a certain threshold, you'll pay a surcharge on top of your standard Part B and Part D premiums. For 2026, single filers earning over $109,000 (or joint filers over $218,000) are subject to IRMAA. The surcharge ranges from an extra $81.20 to over $405/mo depending on income bracket.
If your income has dropped recently due to retirement or a life event, you can appeal your IRMAA surcharge using Form SSA-44.
14
What is the Part B late enrollment penalty?
If you don't sign up for Part B when you're first eligible — and don't qualify for a Special Enrollment Period — you'll pay a 10% penalty added permanently to your Part B premium for each full 12-month period you went without coverage. For example, delaying 2 years adds a permanent 20% surcharge to your monthly premium for as long as you have Part B.
15
What is the Part D late enrollment penalty?
The Part D late enrollment penalty is calculated as 1% of the national base beneficiary premium ($36.78 in 2026) multiplied by the number of full months you went without creditable drug coverage after your IEP ended. Like Part B, this penalty is permanent and added to your monthly Part D premium for as long as you have drug coverage.
16
Is there a limit on Medicare out-of-pocket costs?
Original Medicare (Parts A and B) has no annual out-of-pocket cap — your costs can accumulate without limit. This is one reason many people add a Medicare Supplement (Medigap) plan. Medicare Advantage (Part C) plans are required by law to include an out-of-pocket maximum. Part D now has a $2,100 annual out-of-pocket cap for prescription drug costs as of 2026.
Coverage
17
Does Medicare cover dental, vision, and hearing?
Original Medicare (Parts A and B) generally does not cover routine dental care, eye exams, glasses, or hearing aids. However, many Medicare Advantage (Part C) plans include dental, vision, and hearing benefits as extras. If you have Original Medicare, you may need to purchase separate standalone dental or vision plans to fill this gap.
18
Does Medicare cover prescription drugs?
Original Medicare (Parts A and B) covers some medications — such as those administered in a hospital or doctor's office — but does not cover most outpatient prescription drugs. For retail pharmacy coverage, you need either Medicare Part D (a standalone drug plan added to Original Medicare) or a Medicare Advantage plan that includes Part D coverage. Each plan has its own formulary (drug list) and cost structure.
19
Does Medicare cover care received outside the United States?
In most cases, Original Medicare does not cover healthcare received outside the U.S. There are limited exceptions — such as emergencies on a ship within U.S. territorial waters or when a U.S. hospital isn't reasonably accessible. Some Medigap (Medicare Supplement) plans include foreign travel emergency coverage, and some Medicare Advantage plans may provide limited international benefits.
20
Does Medicare cover long-term care or nursing home stays?
Medicare provides limited coverage for skilled nursing facility (SNF) care — but only after a qualifying 3-day inpatient hospital stay and only for medically necessary skilled care. Days 1–20 are fully covered; days 21–100 require a daily copay ($204.50/day in 2026); after day 100 Medicare pays nothing. Medicare does not cover custodial long-term care (such as help with daily activities in a nursing home). Medicaid or long-term care insurance are the primary options for extended care costs.
21
What is the difference between Medicare and Medicaid?
Medicare is a federal health insurance program primarily for people 65 and older (or those with qualifying disabilities), funded through payroll taxes and premiums — regardless of income. Medicaid is a joint federal-state program that provides coverage to people with low income and limited resources, with eligibility rules varying by state. Some people qualify for both programs simultaneously — they are called "dual eligible" beneficiaries.
Plans & Switching
22
What is the difference between Original Medicare and Medicare Advantage?
Original Medicare (Parts A & B) is run directly by the federal government. It allows you to see any doctor or hospital that accepts Medicare nationwide — with no referrals needed — but has no out-of-pocket maximum and doesn't cover dental, vision, or hearing. Medicare Advantage (Part C) is offered by private insurers approved by CMS. It bundles A & B (and usually D) into one plan, often with added benefits like dental and vision, but typically limits you to a plan network and may require referrals.
23
Can I switch from Medicare Advantage back to Original Medicare?
Yes. You can switch from Medicare Advantage to Original Medicare during the Annual Enrollment Period (October 15 – December 7) or during the Medicare Advantage Open Enrollment Period (January 1 – March 31). Keep in mind that switching to Original Medicare after being in Advantage means you may have difficulty getting a Medigap plan — insurers can use medical underwriting (except in certain states) and may deny or charge more due to pre-existing conditions.
24
What is a Medigap (Medicare Supplement) plan?
A Medigap plan is a supplemental insurance policy sold by private companies that helps pay the out-of-pocket costs left by Original Medicare — such as deductibles, coinsurance, and copayments. Some plans also cover foreign travel emergencies. Medigap plans are standardized (Plans A through N) and cannot be combined with Medicare Advantage. You must have both Part A and Part B to purchase a Medigap plan.
25
Do I need to renew my Medicare plan every year?
Original Medicare is automatically renewable each year — you don't need to take any action to keep it. Medicare Supplement (Medigap) plans also renew automatically as long as you pay your premium. However, Medicare Advantage and Part D plans should be reviewed annually during the Annual Enrollment Period, as plan benefits, premiums, formularies, and provider networks can change each year.
