Medicare is a crucial healthcare program in the United States (US) that provides medical coverage for millions of Americans. But who is eligible for Medicare in the United States (US)? Understanding eligibility criteria is essential for individuals planning their healthcare coverage. In this guide, we will break down who qualifies for Medicare, its different parts, and how to apply.
What Is Medicare In The United States (US)?
Medicare in the United States (US) is a federal health insurance program primarily designed for seniors aged 65 and older. It also provides coverage for certain younger individuals with disabilities and people with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS). The program helps beneficiaries access hospital care, medical services, and prescription drugs, depending on their selected Medicare plan.
Medicare consists of several parts:
- Medicare Part A: Covers hospital stays, skilled nursing facility care, hospice, and some home healthcare services.
- Medicare Part B: Covers outpatient care, doctor visits, preventive services, and medical supplies.
- Medicare Part C (Medicare Advantage): A private insurance option that combines Parts A and B, often including prescription drug coverage and additional benefits.
- Medicare Part D: Covers prescription drug costs.
Understanding who is eligible for Medicare in the United States (US) is key to ensuring proper healthcare coverage at the right time.
Who Is Eligible For Medicare In The United States (US)?
Eligibility for Medicare in the United States (US) depends on age, disability status, and specific medical conditions. The primary groups who qualify include:
Medicare Eligibility Based On Age
Most people become eligible for Medicare when they turn 65. To qualify, they or their spouse must have worked and paid Medicare taxes for at least 10 years. Those who meet this requirement can receive premium-free Medicare Part A and have the option to enroll in Medicare Part B for an additional monthly premium.
Medicare Eligibility For Individuals With Disabilities
Younger individuals under 65 may qualify for Medicare if they have received Social Security Disability Insurance (SSDI) benefits for at least 24 months. After this period, they are automatically enrolled in Medicare.
Medicare Eligibility For People With Specific Medical Conditions
Individuals with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS) qualify for Medicare regardless of age. Those with ESRD must either be on dialysis or have received a kidney transplant, while ALS patients are eligible immediately upon receiving disability benefits.
How To Apply For Medicare In The United States (US)
Automatic Enrollment In Medicare
If you are already receiving Social Security or Railroad Retirement Board (RRB) benefits, you will be automatically enrolled in Medicare Part A and Part B when you turn 65.
Signing Up Manually For Medicare
If you are not receiving Social Security benefits, you must manually enroll in Medicare through the Social Security Administration (SSA). Enrollment can be completed online, over the phone, or at a local SSA office.
Medicare Enrollment Periods
It is important to enroll in Medicare during the correct enrollment period to avoid penalties:
- Initial Enrollment Period (IEP): A seven-month window that starts three months before your 65th birthday and ends three months after.
- General Enrollment Period (GEP): Runs from January 1 to March 31 for those who missed their initial enrollment.
- Special Enrollment Period (SEP): Available for individuals with specific circumstances, such as losing employer health coverage.
What Are The Different Types Of Medicare Plans?
Original Medicare (Part A And Part B)
Original Medicare consists of Part A (hospital insurance) and Part B (medical insurance). It allows beneficiaries to visit any doctor or hospital that accepts Medicare.
Medicare Advantage (Part C)
Medicare Advantage, also known as Part C, is an alternative to Original Medicare. It is offered by private insurance companies and often includes additional benefits such as vision, dental, and prescription drug coverage.
Medicare Part D (Prescription Drug Plan)
Medicare Part D helps cover the cost of prescription drugs. It is available as a standalone plan for those with Original Medicare or included in many Medicare Advantage plans.
Medicare Supplement (Medigap)
Medigap plans help cover out-of-pocket costs like copayments, coinsurance, and deductibles that Original Medicare does not pay.
Costs Associated With Medicare In The United States (US)
Medicare Part A Costs
For most beneficiaries, Medicare Part A is free if they have worked and paid Medicare taxes for at least 10 years. Those who do not meet this requirement may have to pay a monthly premium.
Medicare Part B Costs
Medicare Part B requires a monthly premium, which varies based on income. Additionally, beneficiaries must pay an annual deductible and 20% coinsurance for most services.
Medicare Part C And Part D Costs
The cost of Medicare Advantage (Part C) and Medicare Part D depends on the specific plan and provider. Premiums, deductibles, and out-of-pocket expenses vary.
Why Understanding Medicare Eligibility Is Important
Understanding who is eligible for Medicare in the United States (US) ensures that individuals can access essential healthcare coverage when needed. Proper planning can help beneficiaries make informed decisions and avoid potential penalties for late enrollment.
Conclusion
Medicare is a critical healthcare program in the United States (US) that provides coverage for seniors, disabled individuals, and those with serious medical conditions. Knowing who is eligible for Medicare in the United States (US) is essential to accessing the right benefits at the right time.

Frequently Asked Questions
1. Who Is Eligible For Medicare In The United States (US)?
Eligibility for Medicare in the United States (US) depends on age, disability status, and specific medical conditions. The primary group eligible for Medicare includes individuals aged 65 and older who have worked and paid Medicare taxes for at least 10 years. Additionally, individuals under 65 can qualify if they have received Social Security Disability Insurance (SSDI) benefits for 24 months. People diagnosed with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS) are also eligible for Medicare regardless of age.
U.S. citizens and certain legal permanent residents who have lived in the country for at least five consecutive years may also qualify. If an individual does not meet the work history requirement, they can still enroll in Medicare Part A by paying a premium. Medicare Part B and Part D are available to anyone who meets the age or disability criteria, regardless of work history.
2. What Are The Age Requirements For Medicare Eligibility In The United States (US)?
The standard age requirement for Medicare eligibility in the United States (US) is 65 years old. Individuals who have worked and paid Medicare taxes for at least 10 years (or their spouse has) qualify for premium-free Medicare Part A.
Enrollment in Medicare Part B is optional but recommended to avoid late penalties. If a person is still working and has employer health insurance, they may delay Part B without penalty.
Individuals under 65 may qualify if they have been receiving Social Security Disability Insurance (SSDI) for 24 months or have ESRD or ALS. There are no upper age limits for Medicare eligibility, meaning individuals continue receiving benefits for life. Some seniors may also qualify through a spouse’s work record even if they personally did not work for 10 years. It is important to enroll during the Initial Enrollment Period (IEP) to avoid penalties.
3. Can Individuals Under 65 Be Eligible For Medicare In The United States (US)?
Yes, individuals under 65 can be eligible for Medicare in the United States (US) under specific conditions. The most common way to qualify is through Social Security Disability Insurance (SSDI). If a person receives SSDI for 24 consecutive months, they are automatically enrolled in Medicare Part A and Part B.
Additionally, individuals diagnosed with End-Stage Renal Disease (ESRD) qualify for Medicare regardless of age. ESRD patients must either be on regular dialysis or have had a kidney transplant. Another group that qualifies is individuals with Amyotrophic Lateral Sclerosis (ALS, or Lou Gehrig’s disease). Once diagnosed with ALS and receiving SSDI benefits, they are eligible for immediate Medicare coverage without a waiting period.
People under 65 who do not meet these criteria are generally not eligible for Medicare but may qualify once they reach the standard age of 65.
4. How Do Disabilities Affect Medicare Eligibility In The United States (US)?
Disabilities play a crucial role in Medicare eligibility in the United States (US). If an individual has a qualifying disability and receives Social Security Disability Insurance (SSDI) for 24 months, they automatically become eligible for Medicare.
Certain conditions allow for immediate eligibility. For instance, individuals diagnosed with Amyotrophic Lateral Sclerosis (ALS) do not have to wait 24 months; they qualify as soon as they begin receiving SSDI benefits. Similarly, individuals with End-Stage Renal Disease (ESRD) qualify for Medicare if they require regular dialysis or have had a kidney transplant.
Disabled individuals enrolled in Medicare receive the same benefits as seniors, including hospital coverage (Part A), medical services (Part B), and prescription drug coverage (Part D). Many disabled Medicare beneficiaries also qualify for Medicaid or a Medicare Savings Program, which can help with costs.
5. Are People With End-Stage Renal Disease (ESRD) Eligible For Medicare In The United States (US)?
Yes, individuals diagnosed with End-Stage Renal Disease (ESRD) are eligible for Medicare in the United States (US) regardless of age. Medicare coverage is available if the patient requires dialysis treatments or has had a kidney transplant.
To qualify, individuals must either be receiving dialysis treatments at a Medicare-certified dialysis center or self-dialyzing at home. Additionally, ESRD patients must meet one of the following conditions:
- They have worked and paid Medicare taxes for at least 10 years.
- They are spouses or dependent children of someone who has worked and paid Medicare taxes.
Medicare coverage for ESRD patients typically begins on the first day of the fourth month of dialysis treatment unless they complete home dialysis training, which may allow for earlier coverage. Medicare Part A and Part B cover dialysis services, doctor visits, and kidney transplant-related care.
6. Can Individuals With ALS (Lou Gehrig’s Disease) Be Eligible For Medicare In The United States (US)?
Yes, individuals diagnosed with Amyotrophic Lateral Sclerosis (ALS, or Lou Gehrig’s Disease) are eligible for Medicare in the United States (US) immediately upon receiving Social Security Disability Insurance (SSDI) benefits. Unlike most disabilities, which require a 24-month waiting period, ALS patients qualify for automatic enrollment in Medicare as soon as their SSDI benefits begin.
Medicare for ALS patients covers:
- Medicare Part A (hospital stays, hospice care, and some home health services).
- Medicare Part B (doctor visits, outpatient treatments, durable medical equipment, and therapy).
- Medicare Part D (prescription drug coverage, if enrolled).
Additionally, ALS patients may qualify for Medicare Advantage (Part C), which can provide extra benefits like vision, dental, and hearing coverage. Many ALS patients also apply for Medicaid or supplemental insurance to help cover additional medical costs.
7. Do You Have To Be A U.S. Citizen To Be Eligible For Medicare In The United States (US)?
No, U.S. citizenship is not always required for Medicare eligibility in the United States (US). Lawful permanent residents (green card holders) may qualify if they meet certain conditions.
To be eligible, non-citizens must:
- Be at least 65 years old or meet disability/medical condition requirements.
- Have lived in the U.S. continuously for at least five years.
- Have paid Medicare taxes for at least 10 years, or have a spouse who has.
If a non-citizen has not worked long enough to qualify for premium-free Medicare Part A, they can purchase it by paying a monthly premium. Medicare Part B and Part D are available for any legal resident who meets the eligibility criteria.
Non-citizens who do not meet these requirements may still be eligible for state Medicaid programs to receive healthcare coverage.
8. How Do Work And Tax History Affect Medicare Eligibility In The United States (US)?
Work and tax history play a significant role in Medicare eligibility in the United States (US), particularly for Medicare Part A (hospital insurance). To qualify for premium-free Part A, an individual must have worked and paid Medicare payroll taxes (FICA) for at least 10 years (40 quarters) in the U.S.
If an individual has not worked enough to qualify on their own, they may be eligible based on their spouse’s work record. If neither they nor their spouse has met the work requirement, they can still purchase Part A by paying a monthly premium.
Work history does not affect Medicare Part B (medical insurance) and Part D (prescription drug coverage) eligibility, as anyone who meets the age or disability requirements can enroll in these parts by paying the applicable premiums.
Medicare Advantage (Part C) and Medigap plans also do not require a specific work history.
9. Is There A Minimum Work Requirement To Be Eligible For Medicare In The United States (US)?
Yes, for premium-free Medicare Part A, an individual must have worked and paid Medicare payroll taxes for at least 10 years (40 quarters). This work requirement applies to both U.S. citizens and legal permanent residents who have lived in the U.S. for at least five years.
If an individual has not worked enough, they can still qualify through:
- A spouse who has met the work requirement.
- A former spouse if they were married for at least 10 years and are currently single.
- A deceased spouse if they were married for at least nine months before the spouse’s death.
If a person does not qualify for premium-free Part A, they can purchase it by paying a monthly premium (up to $506 per month in 2024). However, work history does not impact eligibility for Medicare Part B or Part D, which are available to all eligible individuals.
10. Can Non-Working Spouses Be Eligible For Medicare In The United States (US)?
Yes, non-working spouses can be eligible for Medicare in the United States (US) based on their spouse’s work record. If a working spouse has paid Medicare taxes for at least 10 years, their non-working spouse qualifies for premium-free Medicare Part A once they turn 65.
A non-working spouse qualifies for premium-free Part A if they meet one of the following conditions:
- They have been married to a Medicare-eligible spouse for at least one year.
- They are divorced but were married for at least 10 years and are currently single.
- They are widowed and were married for at least nine months before their spouse passed away.
Non-working spouses can also enroll in Medicare Part B and Part D, but they must pay the required monthly premiums. If a non-working spouse does not qualify for premium-free Part A, they can still purchase it at a cost.
11. What Are The Different Parts Of Medicare For Eligible Individuals In The United States (US)?
Medicare is divided into four main parts, each covering different healthcare needs for eligible individuals in the United States (US):
- Medicare Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home healthcare.
- Medicare Part B (Medical Insurance): Covers outpatient care, doctor visits, preventive services, and medical supplies.
- Medicare Part C (Medicare Advantage): Offered by private insurers, it includes Parts A and B and often provides extra benefits like dental, vision, and hearing coverage.
- Medicare Part D (Prescription Drug Coverage): Helps cover the cost of prescription medications.
Some people also purchase Medigap (Medicare Supplement) insurance to help cover out-of-pocket costs not paid by Original Medicare (Parts A and B).
12. What Are The Income Limits To Be Eligible For Medicare In The United States (US)?
There are no income limits to be eligible for Medicare in the United States (US). However, income can affect Medicare costs, particularly for Medicare Part B and Part D premiums.
High-income earners (individuals earning over $103,000 and couples earning over $206,000 in 2024) must pay an Income-Related Monthly Adjustment Amount (IRMAA), which increases their Part B and Part D premiums.
Low-income individuals may qualify for financial assistance through:
- Medicare Savings Programs (MSPs), which help cover Medicare premiums and out-of-pocket costs.
- Extra Help, a program that reduces Part D prescription drug costs.
- Medicaid, which provides additional healthcare benefits for those with limited income and resources.
Even though there are no income limits for Medicare eligibility, financial assistance is available for those who need help covering their Medicare expenses.
13. Can Green Card Holders And Legal Immigrants Be Eligible For Medicare In The United States (US)?
Yes, green card holders (lawful permanent residents) and certain legal immigrants can be eligible for Medicare in the United States (US) if they meet specific conditions.
To qualify for premium-free Medicare Part A, they must have worked and paid Medicare taxes for at least 10 years. If they do not meet this requirement, they can purchase Medicare Part A by paying a monthly premium.
Green card holders and legal immigrants must also have lived in the U.S. continuously for at least five years before becoming eligible. If they meet the age requirement (65+), they can enroll in Medicare Part B and Part D by paying the standard premiums, even if they do not qualify for premium-free Part A.
Immigrants who do not qualify for Medicare may be eligible for state Medicaid programs or other healthcare assistance programs.
14. How Can You Apply If You Are Eligible For Medicare In The United States (US)?
If you are eligible for Medicare in the United States (US), you can apply through the Social Security Administration (SSA). There are several ways to enroll:
- Online: Visit the official Social Security website (www.ssa.gov) and complete the Medicare application.
- By Phone: Call the SSA at 1-800-772-1213 (TTY: 1-800-325-0778).
- In Person: Visit your local Social Security office to apply directly.
If you are already receiving Social Security or Railroad Retirement Board (RRB) benefits, you will be automatically enrolled in Medicare Part A and Part B at age 65. However, if you are not receiving benefits, you must actively enroll.
Enrollment should be completed during the Initial Enrollment Period (IEP), which starts three months before your 65th birthday and lasts for seven months. Late enrollment may result in penalties.
15. When Can You Enroll If You Are Eligible For Medicare In The United States (US)?
If you are eligible for Medicare in the United States (US), you can enroll during specific enrollment periods:
- Initial Enrollment Period (IEP) – This is a 7-month window that begins three months before you turn 65, includes your birth month, and ends three months after your birthday month.
- General Enrollment Period (GEP) – If you missed your IEP, you can sign up between January 1 and March 31 each year, but you may face late penalties.
- Special Enrollment Period (SEP) – If you have qualifying coverage, such as employer-sponsored insurance, you can enroll without penalties once that coverage ends.
- Medicare Advantage & Part D Open Enrollment – From October 15 to December 7, you can join, switch, or drop a Medicare plan.
Enrolling on time is important to avoid late penalties and ensure seamless healthcare coverage.
16. What Happens If You Miss Your Enrollment Period But Are Eligible For Medicare In The United States (US)?
If you miss your Initial Enrollment Period (IEP) but are still eligible for Medicare in the United States (US), you may have to wait until the General Enrollment Period (GEP), which runs from January 1 to March 31 each year. Coverage then starts on July 1, and late penalties may apply.
Late penalties include:
- Part A Penalty: If you have to buy Part A, your premium may increase by 10% for twice the number of years you delayed enrollment.
- Part B Penalty: Your monthly Part B premium may increase by 10% for each full 12-month period you were late.
- Part D Penalty: If you delay enrolling in Medicare Part D and don’t have other creditable coverage, you may face a permanent penalty added to your monthly premium.
Some people qualify for a Special Enrollment Period (SEP), which allows late enrollment without penalties if they had qualifying employer health coverage.
17. Can You Be Eligible For Medicare In The United States (US) If You Still Have Employer Health Coverage?
Yes, you can be eligible for Medicare in the United States (US) even if you still have employer health coverage. If you or your spouse are actively working and have health insurance through an employer with 20 or more employees, you may choose to delay Medicare Part B and Part D without penalties.
However, if your employer has fewer than 20 employees, Medicare becomes the primary insurance, meaning you should enroll in Medicare Part A and Part B to avoid gaps in coverage.
Once your employer coverage ends, you qualify for a Special Enrollment Period (SEP), which allows you to enroll in Medicare without penalties. You have eight months to sign up for Part B and two months to enroll in Part D after losing employer coverage.
18. Are Veterans Eligible For Medicare In The United States (US)?
Yes, veterans are eligible for Medicare in the United States (US) if they meet the standard age (65+) or disability requirements. Veterans who receive healthcare through the Department of Veterans Affairs (VA) can also enroll in Medicare to expand their coverage options.
Key points for veterans:
- Medicare does not replace VA benefits; both can be used together.
- VA benefits cover care at VA facilities, while Medicare covers non-VA hospitals and doctors.
- Medicare Part B is recommended for outpatient services not covered by the VA.
- Medicare Part D is useful if veterans want coverage for prescriptions outside of VA pharmacies.
Veterans can choose to enroll in Medicare Advantage (Part C) for additional benefits like dental and vision coverage. However, Medicare does not cover services received at VA hospitals, so veterans should use both Medicare and VA benefits strategically.
19. What Are The Costs Associated With Being Eligible For Medicare In The United States (US)?
While being eligible for Medicare in the United States (US) provides valuable healthcare benefits, there are costs associated with each part of Medicare:
- Medicare Part A (Hospital Insurance): Free if you or your spouse worked and paid Medicare taxes for 10 years; otherwise, it costs up to $506 per month (2024).
- Medicare Part B (Medical Insurance): Monthly premium of $174.70 in 2024 (higher for high-income earners). Also includes a $240 annual deductible and 20% coinsurance for most services.
- Medicare Part C (Medicare Advantage): Costs vary by plan and provider but may include additional premiums, copays, and deductibles.
- Medicare Part D (Prescription Drug Coverage): Premiums vary by plan, with an average cost of around $34.70 per month (2024). Higher-income individuals pay an IRMAA surcharge.
Additional costs may include Medigap (Medicare Supplement) plans, which help cover out-of-pocket expenses like copayments, coinsurance, and deductibles.
20. Can You Be Eligible For Both Medicaid And Medicare In The United States (US)?
Yes, individuals can be eligible for both Medicare and Medicaid in the United States (US). This is known as dual eligibility. People who qualify for both programs receive additional benefits through Medicare Savings Programs (MSPs) and Medicaid assistance.
Benefits for dual-eligible individuals include:
- Medicaid covering Medicare Part B premiums and possibly Part A premiums (if applicable).
- Reduced out-of-pocket costs, such as copayments, deductibles, and coinsurance.
- Automatic qualification for Extra Help, which lowers prescription drug costs under Medicare Part D.
Dual-eligible individuals may also be enrolled in Medicare-Medicaid Plans (MMPs) or Dual Special Needs Plans (D-SNPs), which offer integrated coverage with added benefits like transportation and long-term care services.
Since Medicaid eligibility is income-based, it is essential to check with your state’s Medicaid office for specific requirements.
