Medicare covers more than 65 million Americans as of 2026, but many people are unsure whether they qualify, when to sign up, or what it actually costs. The core rule is straightforward: you qualify at age 65 if you or your spouse paid Medicare taxes for at least 10 years. But there are two other pathways that apply to younger people, and enrollment timing matters more than most people realize.
Quick Answer: In 2026, you qualify for Medicare at age 65 with 40 quarters of work history, or under 65 if you have received Social Security Disability Insurance (SSDI) for 24 months, have ALS, or have End-Stage Renal Disease. The standard Part B premium is $202.90 per month.

Three Ways to Qualify for Medicare
1. Age 65 or Older
This is the primary eligibility pathway. You qualify for premium-free Part A (hospital insurance) at 65 if you or your spouse worked and paid Medicare taxes for at least 10 years (40 quarters). You do not need to be retired -- you can enroll while still working.
If you have not worked 40 quarters, you can still buy into Part A by paying a premium:
- Fewer than 30 quarters of work: $518 per month (2026)
- 30 to 39 quarters of work: $284 per month (2026)
Part B (medical insurance) is available to everyone who qualifies for Part A, with a standard monthly premium of $202.90 in 2026.
Citizenship requirement: You must be a U.S. citizen or a lawful permanent resident who has lived in the country for at least 5 consecutive years.
2. Disability Under Age 65
You can qualify for Medicare before turning 65 through Social Security Disability Insurance. There are three separate disability pathways:
- SSDI recipients: After receiving SSDI payments for 24 months, Medicare enrollment is automatic. The two-year waiting period begins from your first month of SSDI entitlement, not the date your disability began.
- ALS (Amyotrophic Lateral Sclerosis): If you are approved for SSDI based on ALS, the 24-month waiting period is waived. Medicare coverage begins the same month your SSDI starts.
- End-Stage Renal Disease (ESRD): If you have permanent kidney failure requiring regular dialysis or a kidney transplant, you can enroll in Medicare regardless of age. Coverage generally begins the fourth month after dialysis starts (or sooner in certain cases).
3. End-Stage Renal Disease (ESRD) and ALS
These two conditions are worth highlighting separately because they bypass the normal age and waiting period rules. Any U.S. citizen who develops ESRD or ALS can access Medicare, regardless of work history or age, though ESRD does require some recent work history through either yourself, a spouse, or a parent.
Medicare Parts: What Each Covers and What It Costs in 2026
| Part | What It Covers | 2026 Monthly Premium | 2026 Deductible |
|---|
| Part A | Hospital stays, skilled nursing, hospice | $0 for most (premium-free if 40+ quarters) | $1,736 per benefit period |
| Part B | Doctor visits, outpatient care, preventive services | $202.90 (standard) | $283 per year |
| Part C | Medicare Advantage (bundles A+B+usually D) | Varies by plan | Varies by plan |
| Part D | Prescription drug coverage | Varies by plan | Varies by plan |
Part A inpatient hospital costs in 2026:
- Days 1 to 60: $0 after the $1,736 deductible
- Days 61 to 90: $434 per day
- Days 91 and beyond: $868 per day (lifetime reserve days)
Part B income-related adjustments (IRMAA): If your modified adjusted gross income exceeds $109,000 (single) or $218,000 (married filing jointly), you pay a higher Part B premium. The range in 2026 runs from $284.10 to $689.90 per month depending on income.
Medicare Enrollment Periods
Getting the enrollment timing right matters. Missing your window can mean paying a late enrollment penalty for the rest of your life.
Initial Enrollment Period (IEP)
This is your first and most important window. It spans 7 months total:
- Starts: 3 months before the month you turn 65
- Includes: Your birthday month
- Ends: 3 months after the month you turn 65
When coverage starts: If you enroll in the first 3 months of your IEP, coverage begins the month you turn 65. If you enroll in the final 3 months, coverage is delayed by 1 to 3 months.
Special Enrollment Period (SEP) for Workers
If you are covered by a group health plan through your own or your spouse's current employer at age 65, you can delay Part B without penalty. When that employer coverage ends, you get an 8-month SEP to enroll.
Important: COBRA and retiree coverage do not count as creditable employer coverage. Losing COBRA does not trigger a SEP.
General Enrollment Period (GEP)
If you missed your IEP and do not qualify for a SEP, you can enroll during the General Enrollment Period: January 1 through March 31 each year. Coverage starts July 1. You may face a late enrollment penalty.
Annual Enrollment Period (AEP)
Every year from October 15 through December 7, you can add, switch, or drop Medicare Advantage (Part C) or Part D drug plans. Changes take effect January 1.
Medicare Advantage Open Enrollment Period
January 1 through March 31. If you are already enrolled in a Medicare Advantage plan, you can switch to a different Advantage plan or return to Original Medicare during this window.
Late Enrollment Penalties
Missing enrollment deadlines has lasting financial consequences.
Part B late penalty: 10% added to your premium for each 12-month period you went without Part B coverage and were not covered by employer insurance. At $202.90 per month in 2026, a 2-year gap adds roughly $40.58 to your monthly premium -- permanently.
Part D late penalty: 1% of the national base beneficiary premium ($36.78 in 2026) for each month you delayed enrollment without other creditable drug coverage. This is also permanent.
Medicare and Working Past 65
Many people work past 65 and wonder whether to enroll. The answer depends on your employer's size:
- Employer has 20+ employees: Your group health plan is primary and Medicare is secondary. You can delay Medicare without penalty as long as you remain on the employer plan.
- Employer has fewer than 20 employees: Medicare becomes primary as soon as you are eligible. Delaying Part B here may result in gaps in coverage.
When you retire or lose your employer coverage, you have 8 months to enroll through your SEP.
Medicare Savings Programs: Help with Costs
Even with Medicare, costs can add up. If you have Medicare and a limited income, you may qualify for a Medicare Savings Program through your state Medicaid agency. These programs pay some or all of your Medicare premiums, deductibles, and copayments.
2026 Medicare Savings Program income limits (48 states and DC):
| Program | Who It Helps | Monthly Income Limit (Single) | Monthly Income Limit (Married) | What It Covers |
|---|
| QMB (Qualified Medicare Beneficiary) | Income up to 100% FPL | $1,350 | $1,824 | Part A and B premiums, deductibles, copays |
| SLMB (Specified Low-Income Medicare Beneficiary) | Income 100% to 120% FPL | $1,616 | $2,184 | Part B premium only |
| QI (Qualifying Individual) | Income 120% to 135% FPL | ~$1,819 | ~$2,455 | Part B premium only |
| QDWI (Qualified Disabled Working Individual) | Working disabled under 65 | $4,615 | $6,189 | Part A premium only |
Resource limits for QMB and SLMB: $9,950 (single) or $14,910 (married). Many states have higher limits or no resource limits at all.
You apply for Medicare Savings Programs through your state Medicaid office, not through Medicare directly. Visit CoveredUSA's screener to find out if you might qualify.
How to Apply for Medicare
Step 1: Determine your enrollment window
Use the IEP timeline above. If you are already receiving Social Security benefits before age 65, you will be automatically enrolled in Parts A and B and will receive your Medicare card about 3 months before your 65th birthday.
Step 2: Decide whether to take Part B immediately
If you have employer coverage through a large employer (20+ employees), you may want to delay Part B to avoid paying the premium while your employer plan is primary. If not, sign up during your IEP.
Step 3: Apply
Online: The fastest method. Go to ssa.gov and apply for Medicare without filing for Social Security retirement benefits. The application takes about 10 minutes.
By phone: Call Social Security at 1-800-772-1213, Monday through Friday, 8 a.m. to 7 p.m.
In person: Visit your local Social Security office. An appointment is recommended.
If you are receiving Railroad Retirement Board (RRB) benefits: Contact the RRB directly rather than Social Security.
Step 4: Choose additional coverage
Original Medicare (Parts A and B) alone leaves significant gaps -- including no cap on out-of-pocket costs. Most people add one of the following:
- Medicare Advantage (Part C): Offered by private insurers approved by Medicare. Bundles hospital, medical, and usually drug coverage. Often includes extra benefits like dental and vision.
- Medicare Supplement (Medigap): Works alongside Original Medicare to cover cost-sharing like deductibles and coinsurance. Cannot be combined with Medicare Advantage.
- Part D: Standalone prescription drug coverage for those who stay with Original Medicare.
Step 5: Apply for extra help if needed
If your income is limited, apply for the Extra Help program (also called Low Income Subsidy) for Part D costs, and check Medicare Savings Program eligibility through your state. See Medicare eligibility resources for more detail.

Frequently Asked Questions
What is the age to qualify for Medicare in 2026?
You qualify at age 65 in 2026. If you paid Medicare taxes for at least 40 quarters (10 years) through work, you qualify for premium-free Part A. You can still enroll in Part B for $202.90 per month.
Can I get Medicare if I never worked?
Yes, through a spouse or ex-spouse. If your spouse worked and paid Medicare taxes for 40 quarters, you can qualify for premium-free Part A at 65 based on their work record. If you are divorced, the marriage must have lasted at least 10 years.
What happens if I miss my Medicare enrollment deadline?
Missing your Initial Enrollment Period without qualifying for a Special Enrollment Period means you can only enroll during the General Enrollment Period (January 1 to March 31). You will face a late enrollment penalty on Part B that adds 10% per year of delay, applied permanently to your monthly premium.
Can I have Medicare and employer insurance at the same time?
Yes. Which plan pays first depends on your employer's size. Employers with 20 or more employees: your employer plan is primary. Employers with fewer than 20: Medicare is primary. Coordinating both can reduce your out-of-pocket costs significantly.
Does Medicare cover dental, vision, and hearing?
Original Medicare does not cover routine dental, vision, or hearing care. Some Medicare Advantage plans do include these benefits. You can also purchase separate standalone plans for dental and vision coverage.
How does Medicare work if I am still on disability under 65?
After 24 months on SSDI, you are automatically enrolled in Medicare Parts A and B. You will receive a Medicare card in the mail. You can decline Part B (to avoid the premium) if you have other creditable coverage, but be aware of potential late penalties later.
What is the Medicare Extra Help program?
Extra Help (also called Low Income Subsidy) helps pay for Part D prescription drug costs including premiums, deductibles, and copays. In 2026, you may qualify if your income is below about 150% of the Federal Poverty Level ($21,978 for a single person). Apply through Social Security at ssa.gov or through your state Medicaid agency.
How do I know if I qualify for a Medicare Savings Program?
Medicare Savings Programs are run by state Medicaid agencies. Eligibility is based on income and resources. In 2026, a single person with monthly income under $1,350 may qualify for QMB, which pays Part A and B premiums plus most cost-sharing. Use the CoveredUSA screener to check your eligibility in about 2 minutes.
