Medicare is included with Social Security Disability after 24 months

When you receive Social Security Disability Insurance (SSDI), you automatically become covered by Medicare after you have been receiving benefits for 24 consecutive months. This is not something you have to request — it happens automatically once you hit that two-year mark. Medicare provides hospital insurance (Part A), medical insurance (Part B), and the option to add prescription drug coverage (Part D).

The 24-month waiting period starts from the month your SSDI benefits begin, not from the month you applied. If you were approved retroactively — meaning the Social Security Administration determined your disability started before you applied — those retroactive months count toward your 24 months. You will receive a Medicare card in the mail before your coverage begins.

During the first 24 months while you wait for Medicare, you may be covered by Medicaid instead, depending on your state and income. Medicaid is a separate program run by states, and rules vary significantly. Some states cover working-age adults with disabilities automatically once they receive SSDI; others have income or asset limits that may disqualify you. You should contact your state Medicaid office or your local Social Security office to find out what you are covered by during this waiting period.

Key Takeaways

  • Medicare Part A and Part B begin automatically 24 months after your SSDI benefits start, with no application needed on your part.
  • During the first 24 months of SSDI, you may be covered by Medicaid instead, but coverage rules depend on your state and your income.
  • Medicare Part D (prescription drug coverage) is optional and requires you to enroll during your initial enrollment period or pay a late penalty.
  • Once you turn 65, your SSDI benefits convert to retirement benefits, but your Medicare coverage continues without interruption.
  • If you return to work and your SSDI ends, you can keep Medicare for up to 8.5 years by paying the premiums yourself.

What Medicare Part A and Part B cover

Medicare Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. You do not pay a premium for Part A if you or your spouse paid Medicare taxes while working. When you use Part A services, you pay a deductible for hospital stays and coinsurance for longer stays — the exact amounts change each year.

Medicare Part B covers doctor visits, outpatient services, lab tests, imaging, and some preventive care. Part B has a monthly premium that is deducted from your SSDI check. The standard premium changes each year; in 2024 it was $164.90 per month, but this amount varies based on your income. You also pay a deductible and coinsurance when you use Part B services.

Neither Part A nor Part B covers dental, vision, or hearing aids. If you need these services, you can purchase a separate Medigap or Medicare Advantage plan, though these have their own costs and coverage rules.

Medicaid coverage during the 24-month waiting period

Before Medicare begins, Medicaid may cover your medical expenses. Medicaid is jointly funded by the federal government and states, so each state sets its own income limits, covered services, and rules for who qualifies. Some states use a process called "deemed status," which means that once you are approved for SSDI, you are automatically considered to meet Medicaid's disability requirement — you just have to meet the income and asset limits.

Other states require you to submit a separate Medicaid application and prove your disability again, even though you already have SSDI. A few states have no Medicaid program for working-age adults with disabilities outside of specific circumstances. The fastest way to find out what applies to you is to call your state Medicaid office or visit your state's Medicaid website.

If you do not may have access to for Medicaid and are waiting for Medicare, you may be able to purchase coverage through the Affordable Care Act marketplace. You can also ask your local Social Security office about other programs that might help with medical costs during this gap.

Prescription drug coverage under Medicare Part D

Medicare Part D is optional prescription drug coverage that you can add to your Medicare. It is not automatic — you have to enroll during your initial enrollment period, which is the seven-month window that includes the month you turn 65 or the month your Medicare begins, whichever is later. If you do not enroll during this window and you do not have other creditable drug coverage, you will pay a late enrollment penalty for as long as you have Medicare.

Part D plans are offered by private insurance companies approved by Medicare. Each plan has a different list of covered drugs, different costs, and different pharmacies. You can compare plans on Medicare.gov or call 1-800-MEDICARE. Most plans have a monthly premium, a deductible, and copayments or coinsurance for each prescription.

If your income is low, you may may have access to for the Low-Income Subsidy program, which reduces your Part D costs. You can apply for this through Social Security or Medicare.

What happens to your insurance if you return to work

SSDI includes a work incentive called the Trial Work Period, which allows you to test your ability to work without immediately losing benefits. During the Trial Work Period, you can earn any amount and still receive your full SSDI check. The Trial Work Period lasts nine months within a rolling 60-month window.

After the Trial Work Period ends, if your earnings are high enough, your SSDI benefits will stop. However, you can keep your Medicare coverage for up to 8.5 years by paying the premiums yourself — you do not have to give it up immediately. This is called Extended Medicare Coverage. You must pay Part B and Part D premiums out of pocket, but Part A is usually free if you worked long enough to earn it.

If you stop working again and your earnings drop below the limit, you can restart your SSDI benefits without going through the approval process again. Your Medicare coverage will continue during this time.

Medicare Advantage and Medigap plans

Once you have Medicare, you can choose to stay on Original Medicare (Part A and Part B) or switch to a Medicare Advantage plan (also called Part C). Medicare Advantage plans are offered by private insurance companies and usually have lower out-of-pocket costs than Original Medicare, but they restrict which doctors and hospitals you can use. Some Medicare Advantage plans include prescription drug coverage, dental, vision, and hearing benefits.

Alternatively, you can keep Original Medicare and purchase a Medigap policy from a private insurer to cover some of the costs that Medicare does not pay. Medigap policies do not include prescription drug coverage — you would still need Part D for that.

You have the right to switch between Original Medicare and Medicare Advantage during the Annual Enrollment Period (October 15 to December 7 each year). If you switch to Medicare Advantage and later want to go back to Original Medicare, you may have limited options, so understand the rules before you change.

What happens when you turn 65

When you turn 65, your SSDI benefits automatically convert to Retirement Insurance Benefits at the same payment amount. Your Medicare coverage does not change — it continues without interruption. You do not need to do anything; the conversion happens automatically.

The only thing that may change is your Medicare premiums. If your income has increased, your Part B and Part D premiums may be higher due to Income-Related Monthly Adjustment Amounts (IRMAA). These are surcharges based on your modified adjusted gross income from two years prior.

Can I switch from Original Medicare to Medicare Advantage?

Yes, during the Annual Enrollment Period (October 15 to December 7 each year). However, switching back to Original Medicare later may be difficult, so compare plans carefully before you change. You can also call 1-800-MEDICARE for help comparing options.

You can keep Medicare for up to 8.5 years by paying the premiums yourself. You must pay Part B and Part D premiums, but Part A is usually free. If you stop working again and your earnings drop below the limit, your SSDI can restart and Medicare continues.

Does Medicare cover dental, vision, or hearing aids?

Original Medicare does not cover these services. Some Medicare Advantage plans include dental, vision, or hearing benefits, but coverage varies by plan. You can also purchase standalone dental or vision plans, or look for community health programs that offer these services at reduced cost.
