You probably know that Medicare coverage is available to people age 65 or older. You may also know that Medicare coverage is available for people with disabilities.

If you qualify for disability benefits from the Social Security Administration, you can get Medicare coverage. Knowing when your Medicare coverage will start, what it will cover, and much it will cost can help you make important decisions.

You can qualify for Medicare if you have a disability and have been approved for Social Security Disability Insurance (SSDI). In most cases, you’ll need to wait 24 months before your Medicare coverage begins.

There is a 2-year waiting period that begins the first month you receive a Social Security benefit check. At the start of your 25th month of SSDI coverage, you’ll be automatically enrolled in Medicare.

There are two exceptions to the 2-year waiting period. If you have amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s Disease, you’ll be enrolled in coverage in the first month you receive SSDI. If you have end stage renal disease (ESRD), your Medicare coverage normally begins after you’ve received 3 months of dialysis treatment.

Am I eligible for Medicare disability coverage if I am younger than age 65?

Medicare disability coverage doesn’t have an age requirement. You can get Medicare coverage as long as you have a disability and have been approved for SSDI.

The first step to getting Medicare coverage if you have a disability is to apply for Social Security Disability benefits. Your disability will need to meet the standards set by the Social Security Administration to qualify for coverage. Generally, this means you are unable to work and that your condition is expected to last for at least a year.

Medicare doesn’t determine who is eligible for disability coverage. You don’t need to take any further steps if the Social Security Administration has approved your disability application. You’ll just need to wait the required 24 months, and you will be automatically enrolled in Medicare.

Once you’ve been approved for SSDI, you’ll be automatically enrolled at the start of your 25th month of receiving benefits. You’ll receive your Medicare card in the mail during your 22nd month of SSDI benefits. Once you’re eligible, you’ll have coverage from Medicare parts A and B, also known as original Medicare.

  • Medicare Part A (hospital insurance). Part A is used to pay for hospital stays and other types of short-term patient care, such as skilled nursing facilities. People generally don’t pay a premium for Part A coverage.
  • Medicare Part B (medical insurance). Part B is used to pay for a wide range of medical services, including doctor and specialist appointments, emergency room visits, ambulance services, medical equipment, preventive care, and some medications. You’ll normally pay a monthly premium for Part B coverage.

Your Medicare costswill depend on your specific circumstances. It’s important to know that unlikestandard insurance plans, each Medicare part has its own costs and rules.

Part A costs

You won’t typically pay a premium for Medicare Part A. While there are some circumstances when people do need to purchase Part A coverage, people who receive Social Security benefits or benefits from the Railroad Retirement Board are able to get free coverage. This means you won’t pay for Medicare Part A as long as you’ve been receiving SSDI benefits for 24 months.

In 2021, hospitalization costs with Medicare Part A include:

  • Deductible: $1,484 for each benefit period
  • Days 1–60: after the deductible has been met, inpatient stays will be completely covered until the 60th day the benefit period
  • Days 61–90: $371 per day coinsurance
  • Day 91 and above: $742 per day coinsurance until you exhaust your lifetime reserve days (60 days for a lifetime)
  • After 60 lifetime reserve days: you pay all costs

Part B costs

Your Medicare Part B premium will be deducted from your SSDI check. The standard Part B premium for 2021 is $148.50 per month.

The deductible for Medicare Part B in 2021 is $203. After you meet the deductible, some services are covered in full. You’ll pay 20 percent of the Medicare-approved amount for other services.

Some people choose to decline Medicare Part B coverage. Often, this is because they can get more affordable coverage from another source, such as their spouse’s employer. You can choose to not to sign up for Medicare Part B coverage if you have other coverage options.

There will be instructions on how to defer Part B coverage included with your Medicare card when it arrives in the mail. However, you might pay a late enrollment penalty later if you don’t have a qualifying reason for not enrolling in Part B when you first became eligible.

You might be eligible for assistance paying your premiums, deductibles, coinsurance, or copayments.

There are currently four Medicare savings programs available to help cover these costs:

These plans are designed to help people who fall under preset income levels pay for their Medicare coverage. You’ll need to meet income requirements to qualify.

Private Medicare plans

Once you’re eligible for Medicare parts A and B, you’ll have the option to purchase Medicare plans sold by private insurance companies.

  • Medicare Part C (Medicare Advantage). Medicare Advantage plans can offer more coverage options than original Medicare. This coverage is offered by private companies that have contracts with Medicare. You’ll need to be enrolled in parts A and B and sometimes pay an added premium with a Medicare Advantage plan.
  • Medicare Part D. Part D is prescription drug coverage. You can use this plan to help offset the cost of your medications. Premiums for Part D depend on your income. A program called Extra Help can help cover Medicare Part D and your prescription drugs costs if you have limited income or resources.
  • Medicare supplement insurance (Medigap). Medigap plans are sold by private insurance companies approved by Medicare to help you cover the costs of coinsurances, copays, and other expenses Medicare doesn’t pay.
