Am I Eligible for Medicare?

Eligibility Overview

Medicare eligibility is primarily based on age, disability status, or specific medical conditions. Most Americans become eligible at age 65, but there are several pathways to qualify earlier. Understanding which category applies to you is the first step toward getting the coverage you need.

• Age 65+

  Most common path

• Under 65 with Disability

  After 24-month wait

• ALS Diagnosis

  Immediate eligibility

• ESRD

  Kidney failure at any age

Age 65+ Eligibility

The most common way to qualify for Medicare is by turning 65. If you're a U.S. citizen or permanent legal resident who has lived in the country for at least 5 continuous years, you're eligible for Medicare at age 65 — regardless of your health status or whether you're still working.

Under 65 Eligibility

You don't have to be 65 to qualify for Medicare. Younger individuals with qualifying disabilities or certain medical conditions can receive Medicare coverage. Here are the main pathways:

• Age 65 or Older

  The most common path to Medicare eligibility. You qualify at age 65 regardless of whether you're still working.

  Requirements:

  • U.S. citizen or permanent legal resident for 5+ continuous years
  • Age 65 or approaching 65
  • You or your spouse paid Medicare taxes for at least 10 years (40 quarters)

  Note: If you're receiving Social Security benefits, you'll be automatically enrolled in Medicare Parts A and B when you turn 65.

• Disability (under 65)

  Younger individuals with qualifying disabilities can receive Medicare after a 24-month waiting period.

  Requirements:

  • Receiving Social Security Disability Insurance (SSDI) for 24 months
  • U.S. citizen or permanent legal resident
  • Disability approved by the Social Security Administration

  Note: The 24-month waiting period begins from the date you first receive SSDI benefits, not from when you applied.

• ALS (Lou Gehrig's Disease)

  If you've been diagnosed with ALS, you qualify for Medicare immediately — no waiting period required.

  Requirements:

  • Diagnosed with Amyotrophic Lateral Sclerosis (ALS)
  • Eligible for Social Security disability benefits
  • No 24-month waiting period required

  Note: Medicare coverage begins the same month your SSDI benefits start. This is the only condition that waives the 24-month waiting period.

• End-Stage Renal Disease (ESRD)

  Permanent kidney failure requiring dialysis or a kidney transplant qualifies you for Medicare at any age.

  Requirements:

  • Diagnosed with End-Stage Renal Disease (ESRD)
  • Need regular dialysis or have had a kidney transplant
  • You, your spouse, or your parent has paid Medicare taxes sufficiently

  Note: Coverage typically begins the 4th month of dialysis treatments, though it can begin sooner if you receive a kidney transplant or start home dialysis training.

End-Stage Renal Disease (ESRD)

End-Stage Renal Disease (ESRD) — permanent kidney failure requiring dialysis or a kidney transplant — qualifies you for Medicare at any age. This is the only medical condition (besides ALS) that provides a direct path to Medicare regardless of age or disability status.

Citizenship && Residency Requirements

In addition to meeting age or disability requirements, you must also meet citizenship or residency criteria to qualify for Medicare.

Work History && Part A Premiums

Your work history (or your spouse's) determines whether you receive premium-free Part A. Medicare taxes are paid through payroll deductions (FICA), and the number of "quarters" you've worked determines your premium.

• 40+ quarters (10+ years)

  You or your spouse paid Medicare taxes for 10 or more years

  $0/month

• 30–39 quarters (7.5–9.75 years)

  Reduced premium — close to the 40-quarter threshold

  $311/month (2026)

• Under 30 quarters

  Full premium required — fewer than 30 quarters of Medicare tax payments

  $565/month (2026)

Special Situations

Several common life situations can affect your Medicare eligibility and enrollment timing. Here's what you need to know:

• Working past 65

  If you're still working at 65 and have employer coverage through a company with 20+ employees, you may delay Medicare enrollment without penalty. Your employer plan is considered "creditable coverage."

  What to Do:

  You have a Special Enrollment Period (SEP) of 8 months after you or your spouse stops working or loses employer coverage.

• Veterans with VA Benefits

  VA benefits and Medicare are separate programs. You can have both, and many veterans choose to enroll in Medicare Part A (which is usually free) as a backup.

  What to Do:

  Enrolling in at least Part A is recommended even if you primarily use VA healthcare.

• Federal Employees (FEHB)

  Federal Employee Health Benefits (FEHB) and Medicare can work together. FEHB continues into retirement, and adding Medicare can reduce your out-of-pocket costs.

  What to Do:

  Most federal retirees benefit from enrolling in both Part A and Part B alongside FEHB.

• COBRA Coverage

  COBRA is not considered creditable coverage for Medicare purposes. If you're 65+ and on COBRA, you should enroll in Medicare during your Initial Enrollment Period to avoid late penalties.

  What to Do:

  Do not delay Medicare enrollment because of COBRA — you may face permanent late enrollment penalties.
