Medicare Supplements for Disabled People Under 65

What Is Medicare?

As was already mentioned, Medicare is a federal health insurance program established in 1965 and that, at the moment, covers over 61 million Americans. Although Medicare is mostly meant for people aged 65 and over, there are some instances in which you can be eligible for it even if you are under 65. In fact, over 9 million of those who are covered by Medicare have not yet turned 65.

In order to be eligible for Medicare coverage before you turn 65, you need to have a disability as well as meet other conditions. Those other conditions qualifying someone for Medicare under 65 are:

• having received Social Security Disability benefits (SSDI) for at least 24 consecutive months. Once the two years have passed, an individual will automatically be enrolled in Original Medicare Part A and B.

• End-Stage Renal Disease (ESRD) or Lou Gehrig’s disease (Amyotrophic Lateral Sclerosis, ALS)

Immediate Medicare

When it comes to both End-Stage Renal Disease (ERSD) and Lou Gehrig’s Disease (ALS), an individual doesn’t have to collect the disability benefits for 24 months. Instead, they are enrolled as soon as they start receiving benefits. However, there is a five-month waiting period for those with ESRD. There was one also for those with ALS. However, as of 2020, it has been eliminated due to the ALS Disability Insurance Access Act of 2019.

It’s important to note that once you confirm that you are eligible for Medicare benefits, the offer that will be presented to you will be the same one that a person turning 65 gets. You will have a few different options when it comes to how you want to proceed, so let’s take a look at them together.

Eligibility and Enrollment for Disabled People Under 65

If you are under age 65 and living with a disability, you may be eligible for Medicare coverage through a process that begins with qualifying for Social Security Disability benefits. The Social Security Administration (SSA) must first determine that you have a disabling impairment that prevents you from engaging in substantial gainful activity. Once approved, you typically need to receive disability benefits for 24 months before you become eligible for Medicare. After this waiting period, you are automatically enrolled in Medicare Part A (hospital insurance) and Part B (medical insurance), giving you access to a full range of health care services.

There are important exceptions to this rule. Individuals diagnosed with End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS, also known as Lou Gehrig’s disease) do not have to wait 24 months to receive Medicare coverage. For these conditions, Medicare eligibility can begin much sooner, ensuring that those with urgent health care needs can access essential services without delay.

Understanding your eligibility and enrollment options is crucial. Once you are eligible for Medicare, you will receive a Medicare card and can begin using your benefits for hospital stays, doctor visits, and other covered services. It’s important to review your options carefully, as enrolling in Medicare Part B is necessary to access many medical insurance benefits. If you have questions about your eligibility or the enrollment process, contacting the Social Security Administration or a Medicare expert can help ensure you receive the coverage and health care services you need.

Original Medicare

The most basic Medicare coverage is Original Medicare. Original Medicare consists of two parts; Part A and Part B.

Medicare Part A, also referred to as Hospital Insurance, is responsible for your inpatient care which includes things like a hospital stay, hospice or home healthcare. To understand what is covered under Medicare Part B, you can learn more about outpatient prescription drugs typically administered by a medical professional in a facility. What’s more, Medicare Part A also covers care that you have received through facilities like critical access hospitals, acute care hospitals, inpatient rehabilitation facilities or through participation in a clinical research study (not all of them qualify, however, so just keep that in mind).

Part B, on the other hand, also known as Medical Insurance, covers most of the outpatient costs and physician services such as regular doctor visits or preventative screenings. It also covers medical supplies and equipment that help you function and perform daily activities known as Durable Medical Equipment or DME for short. DME includes wheelchairs, commode chairs, artificial limbs, oxygen supplies, pacemakers, and any appliances that make breathing easier, among other things.

In some situations, Medicare acts as the primary payer when you have other health insurance, meaning it pays first before your other insurance covers any remaining costs.

What Is Not Covered by Medicare?

Although Medicare covers most health services, it doesn’t cover everything. There are certain health care services that don’t fall under Original Medicare coverage. In case you need to use one of them, you will have to pay for them from your own pocket. Health care services not covered by Medicare include: 

• dentistry (most dental health procedures will involve out-of-pocket costs) For details on dental care and available insurance coverage please see Does Medicare Cover Dental?

• long-term care

• eye exams when you need them to get a prescription for glasses or contact lenses.

• cosmetic surgeries

• hearing aids, as well as the exams you need to make them fit you

Original Medicare also doesn’t include prescription drug coverage. For that, you need to purchase Part D. 

Medicare Advantage Plans for Disabled Under 65

Medicare Advantage plans are plans offered by a private health insurance company that has been approved by CMS (Centers for Medicare and Medicaid Services) and that serve as an alternative to Original Medicare.

Medicare Advantage plans are also available to Medicare recipients under 65 with disabilities, providing them with additional options beyond Original Medicare.

Advantage plans usually offer you the same services as Original Medicare in addition to some other benefits, like prescription drug coverage or limited dental and/or vision care.

Advantage and Medigap Differences

So, how exactly are Original Medicare plans and Medicare Advantage plans different from each other, aside from what we have already mentioned? Here is a short comparison of the most important aspects of both health insurance options for the disabled under age 65 and others over age 65:

• Access to Doctors: With regular Medicare, you can visit any doctor or hospital that accepts it across the whole of the US. With the Medicare Advantage plan, you will most likely have to visit a local doctor that is within the insurance company’s network.

• Referral: With regular Medicare coverage you don’t need to have a referral in order to visit a specialist. With Medicare Advantage, a referral might be needed depending on the plan..

• Out-of-pocket costs limits: With traditiinal Medicare, there is no limit in terms of how much you’d have to pay out-of-pocket. Medicare Advnantage plans put a cap onyour financial risk. With Medicare Advantage, there is a yearly limit on your out-of-pocket payments for services that fall under the Medicare Part A and Part B coverage. This maximum out of pocket limit can change annually.

• Secondary payer: If you have other insurance, such as employer-based health coverage, Traditional Medicare may act as a secondary payer. This means Medicare covers costs that your primary insurance does not pay, especially for individuals with disabilities who are working.

• Prior Authorizations: With Original Medicare your doctor does not need approval for each procedure or service.  With an Advantage plan the doctor is required to get approval, called prior authorizations, from the insurance company for each non-urgent procedure or service.  Emergency procedures are exempt.

• Travel Health Care: Traditional Medicare does not typically cover services outside the United states. Some Medicare Advantage plans and Medicare supplement plans have limited urgent care coverage while traveling outside the U.S..

Most Common Medicare Advantage Plans 

Not all Medicare Advantage plans are created equal.  In 2025 there are nearly 4,000 Medicare Advantage plans offered across the U.S. Of these, more than 80% were either an HMO or PPO, including Special Needs Plans.

• Health Maintenance Organization (HMO): With an HMO health insurance plan, you can use the services of doctors, health professionals, and hospitals that are within a plan’s network. There is an exception for emergency care, out-of-area urgent care, or out-of-area dialysis.   Those are covered by the HMO plan even when out-of-network. 

• Prefered Provider Organization (PPO): With PPO coverage, you can not only use the plan’s network of doctors and other health professionals, but you may be able to  take advantage of out-of-network services at a higher cost.  The out-of-network doctor must accept your insurance.  They are not required to do so. Out of network services typically cost more.

• Special Needs Plans (SNP): Special Needs Plans provide health care coverage to Medicare beneficiaries that suffer from specific diseases or health care needs, or are on a limited income. A Special Needs Medicare Advantage plan is usually either an HMO or PPO plan with extra services tailored specifically to those with specific chronic illness or condition. In order to be eligible for a Special Needs Plan, you need to live in the plan’s service area and meet one of the other requirements:

  • You have one or more chronic illnesses included in the list of conditions qualifying for C-SNP also called Chronic Condition SNP:

    • Chronic dependence (for instance alcohol)

    • Autoimmune disorder

    • Cancer (does not include pre-cancer conditions)

    • Cardiovascular disorder

    • Chronic Heart Failure

    • Dementia 

    • Diabetes mellitus

    • End-stage liver disease

    • End-Stage Renal Disease (ESRD) when you need dialysis 

    • Severe hematologic disorders

    • HIV/AIDS

    • Chronic lung disorders

    • Chronic and disabling mental health conditions

    • Neurologic disorders

    • Stroke

  • You live in a facility (e.g. a nursing home) or you need nursing care in your home (this type of SNP is also called I-SNP or Institutional SNP) 

  • You are eligible for both Medicare coverage and Medicaid coverage (this type of SNP is also known as D-SNP or Dual Eligible SNP) 

Medicare Supplement Plan

A Medicare Supplement Plan adds to your Original Medicare.  Also known as Medigap insurance, these plans help you pay the deductibles, copay and coinsurance that Original Medicare leaves as your responsibility to pay. Medigap policies are sold by private insurers and brokers. Medigap insurers may have different rules and premiums for people under 65 with disabilities, and individuals are responsible for paying the monthly premium for their chosen Medigap plan.

When it comes to how many plans you can choose from when you  enroll in Medicare Supplement insurance, you have 12 standardized plans to choose from  A, B, C, D, F, G, K, L, M, and N. Plan’s G and F have high deductible options.  Depending on which plan you choose, you will be provided with different benefits.

Medicare Disability Supplemental Insurance Under 65 Around the Country

State regulations determine whether disabled beneficiaries under 65 can access Medigap plans and under what terms.

Unfortunately, there is no federal law that would make a Medigap policy accessible to all disabled Medicare beneficiaries. States can make their own decision when it comes to making Medigap plans available to those under 65. Those states that do allow under 65 Medigap plans only offer them during the first six months (180-days) that a person has Medicare Part B.

In terms of accessibility to Medicare Supplemental Insurance for the disabled under 65, states can be divided into five categories:
