Most people on SSDI do not pay a monthly premium for Medicare Part A

If you receive SSDI benefits, you are automatically enrolled in Medicare Part A after you have been on SSDI for 24 months. Part A covers hospital stays, skilled nursing care, hospice, and some home health services. You do not pay a monthly premium for this coverage — it is included as part of your SSDI may be able to access.

The only cost you might pay for Part A is a deductible when you actually use hospital services. In 2024, that deductible is $1,676 per hospital stay (this amount changes each year). If you use hospital services, you pay this amount out of pocket before Medicare Part A begins to pay. After you meet the deductible, Medicare covers most of your hospital costs.

You do not need to do anything to get Part A — Social Security enrolls you automatically once your 24-month waiting period ends. You will receive a Medicare card in the mail before your coverage starts.

Key Takeaways

  • You pay no monthly premium for Medicare Part A when you are on SSDI, but you do pay a deductible ($1,676 in 2024) if you are admitted to a hospital.
  • Medicare Part A is automatic after 24 months on SSDI — you do not need to sign up or take any action.
  • Part A covers hospital stays, skilled nursing facilities, hospice, and some home health services, but not outpatient doctor visits or prescription drugs.
  • If you want coverage for doctor visits and prescription drugs, you will need to enroll in Medicare Part B and Part D, which do have monthly premiums.
  • Your Social Security office will send you a Medicare card before your Part A coverage begins.

What Part A actually covers and what it does not

Medicare Part A is hospital insurance. It pays for inpatient hospital care — meaning you stay overnight or longer. It also covers skilled nursing facility care (a facility that provides medical care after a hospital stay), home health services ordered by a doctor, and hospice care.

Part A does not cover outpatient services like doctor office visits, lab tests, X-rays, or prescription medications. Those services are covered by Medicare Part B (which requires a separate monthly premium) and Medicare Part D (prescription drug coverage, also with a monthly premium). Many people on SSDI choose to enroll in Part B and Part D even though they are not automatic, because without them they have no coverage for routine doctor visits or medications.

The difference between Part A and Part B premiums

Because Part A is automatic and free, many people assume all Medicare is free on SSDI. That is not true. Medicare Part B requires a monthly premium that is deducted from your SSDI check. In 2024, the standard Part B premium is $164.90 per month, though the amount varies based on your income.

You are not automatically enrolled in Part B. When you turn 65 or become may be able to access for Medicare through SSDI, you have a window to enroll. If you miss that window and do not enroll when you are first may be able to access, you may face a permanent penalty on your premium. Many people on SSDI choose to enroll in Part B during their initial may be able to access period to avoid this penalty, even if they do not plan to use it right away.

Medicare Part D (prescription drug coverage) also has a monthly premium that varies by plan — typically between $5 and $100 per month depending on which plan you choose. Like Part B, if you do not enroll when you first become may be able to access and you later want coverage, you may pay a penalty.

When you might owe money beyond the deductible

Even after you meet the Part A deductible, you may owe money for some services. If you stay in a hospital for more than 60 days in a single benefit period, you owe a coinsurance amount for days 61 through 90. In 2024, that coinsurance is $419 per day. If you stay longer than 90 days, the costs rise further.

For skilled nursing facility care, you pay nothing for the first 20 days after a hospital stay. From day 21 through day 100, you pay a coinsurance amount (in 2024, $209.50 per day). After 100 days, you pay all costs yourself.

These amounts change every year, so if you are facing a long hospital stay or skilled nursing care, ask the facility or your Social Security office for the current year's costs.

How Part A enrollment works on SSDI

You do not explore for Part A. Social Security tracks your SSDI may be able to access and automatically enrolls you 24 months after your SSDI benefits begin. You will receive a Medicare card in the mail about two weeks before your coverage starts. The card shows your Medicare number and which parts of Medicare you are enrolled in.

Your SSDI case worker or a Social Security office can tell you the exact date your Part A coverage will begin. If you do not receive your Medicare card by the expected date, contact Social Security to request a replacement.

If you want to enroll in Part B or Part D, you must take action yourself. You can enroll online at Medicare.gov, by phone at 1-800-MEDICARE, or in person at a Social Security office. The important date to enroll without penalty is usually three months after the month you first become may be able to access.

What happens if you have other health insurance while on SSDI

If you have health insurance through a job, a family member, or Medicaid, you can keep that coverage even after Medicare Part A begins. Medicare becomes your secondary insurance, meaning it pays after your other insurance pays its share.

If you have Medicaid, the rules vary by state. Some states will keep you on Medicaid after you enroll in Medicare; others will not. Contact your state Medicaid office to understand how your coverage will change when Medicare Part A starts.

If you have employer health insurance and you turn 65 or become may be able to access for Medicare through SSDI, you should contact your employer's benefits office to understand how your coverage will coordinate with Medicare.

Frequently Asked Questions

Do I have to pay for Medicare Part A if I am on SSDI?

No. Part A is free — you pay no monthly premium. You may pay a deductible if you are admitted to a hospital, but the premium itself is included in your SSDI benefits. Part B and Part D have separate monthly premiums if you choose to enroll in them.

When does Medicare Part A start after I begin receiving SSDI?

Medicare Part A begins automatically 24 months after your SSDI benefits start. You will receive a Medicare card in the mail about two weeks before coverage begins. Social Security will tell you the exact start date if you ask.

What is the difference between the Part A deductible and the Part B premium?

The Part A deductible is a one-time cost you pay only if you are admitted to a hospital ($1,676 in 2024). The Part B premium is a monthly cost deducted from your SSDI check whether you use services or not ($164.90 per month in 2024). Part A is automatic and free; Part B requires you to enroll and pay monthly.

Can I refuse Medicare Part A when I become may be able to access?

You cannot refuse Part A itself, but you can delay enrolling in Part B and Part D if you have other coverage.
