How Medicare Enrollment Works When SSDI Reaches Retirement Age

Published:

Updated:

When Social Security Disability Insurance (SSDI) converts to retirement benefits at full retirement age, your Medicare enrollment and coverage continue without interruption. You keep the same Medicare card and number. 

This article explains what changes and what stays the same during this conversion. It also discusses what happens if you’ve been receiving other benefits.

SSDI Conversion at Full Retirement Age

SSDI provides monthly payments when a condition prevents you from working or drastically limits your ability to work for at least 12 months or is expected to result in death. To qualify, you must have enough work credits and recent work credits from paying Social Security taxes.

When you get SSDI and reach full retirement age, the Social Security Administration (SSA) automatically converts your SSDI benefits to Social Security retirement benefits. Your gross monthly benefit stays the same until the next cost-of-living adjustment. Social Security records and notices start calling the payment a retirement benefit rather than a disability benefit.

This SSDI-to-retirement conversion doesn’t change your existing Medicare coverage. Your Medicare Part B premium payment or deduction also stays the same. 

Does SSDI Become Retirement at Age 65?

Age 65 and full retirement age are different milestones. If you’ve been a legal resident of the U.S. or a U.S. territory for at least five years, your Medicare eligibility begins at age 65. 

When you get SSDI, your Medicare eligibility begins after 24 months of entitlement or at age 65, whichever comes first. The 24-month Medicare waiting period is waived in Amyotrophic lateral sclerosis (ALS) cases and reduced in end-stage renal disease cases. You may have Medicare for years before your SSDI converts to retirement benefits. 

Your Social Security full retirement age is between 66 and 67, depending on your birth year. Your retirement age is 67 if you were born in 1960 or later.

You get an SSA notice about the benefit change two to three months before you reach Social Security full retirement age. 

Medicare Coverage After SSDI Converts

Your existing Medicare coverage continues to include:

  • Medicare Part A: Hospital coverage for inpatient care in hospitals, skilled nursing facilities, hospice, and some home health care.
  • Medicare Part B: Medical coverage for doctors, specialists, outpatient care, home health care, medical equipment, prevention services, and annual wellness visits.
  • Medicare Advantage: Optional private Medicare coverage through Medicare-approved companies that replaces Original Medicare. It bundles Part A and Part B benefits and usually Part D. Plans provide benefits that Original Medicare doesn’t like vision, hearing, and dental.
  • Medicare Part D: Optional prescription drug coverage through private Medicare-approved providers.
  • Medigap: Private supplemental insurance used with Original Medicare to help pay out-of-pocket costs like copays, coinsurance, and deductibles.

What Changes When SSDI Reaches Full Retirement Age 

The SSDI-to-retirement conversion changes how the SSA classifies and manages your Social Security benefit but not how you receive Medicare, your monthly payment, or when you get paid.

This table provides a look at what changes and what doesn’t.

Changes Stays the Same
The benefit classification changes from disability to retirement Medicare coverage
SSA records and notices use retirement language Medicare number and card
Disability medical reviews stop Gross Social Security payment
Disability-specific work rules no longer apply Existing payment method and normal schedule

SSDI and SSI Changes at Retirement Age 

Receiving Both SSDI and SSI

To get Supplemental Security Income (SSI), you must have limited income and resources and either have a qualifying disability or be age 65 or older. It’s not based on your work record.

If you receive both SSDI and SSI, only the SSDI payment converts to retirement benefits. SSI benefits continue. 

SSDI benefits count as income in your financial assessment. Since your retirement payment is the same as your previous SSDI payment, you still qualify for SSI unless something else changed.

Receiving Only SSI

If you only receive SSI, the SSA requires that you apply for retirement benefits when you’re eligible. You may qualify for Social Security retirement benefits even if you were denied for SSDI because the recent-work rule used for SSDI and disability rules no longer apply. You still need 40 work credits on your record to get Social Security retirement though.

You may also qualify for retirement benefits on a spouse’s or former spouse’s work record if you don’t have enough credits on your own record. You can get survivor benefits if your spouse had 40 work credits and died. You can check your estimated retirement benefit through your online Social Security account or by talking to the SSA.

As long as your income and resources are still within the limits, you continue to get SSI payments.

Workers’ Compensation or Other Public Disability Benefits

Workers’ compensation and other public disability benefits reduce SSDI payments because of offset rules. You’re only allowed to get 80% of your average pre-disability earnings from combined benefits when you’re on SSDI. 

When you reach full retirement age, offsets no longer apply. How much your retirement payment will be after the conversion from SSDI depends on your individual record.

Where to Get Help With Medicare and SSDI Retirement Changes 

Contact the SSA if you are near full retirement age and don’t get a notice or if your notice has an incorrect gross benefit amount, incorrect personal information, or Medicare Part B premium deductions that don’t match your existing arrangement. You can also ask the SSA about SSI eligibility with retirement benefits.

Contact Medicare or your private plan if records show that your existing coverage is inactive or incorrect. Contact the State Health Insurance Assistance Program (SHIP) for free Medicare counseling if you are interested in changing your coverage during the next open enrollment period. The SSDI to retirement benefits transition doesn’t create an open enrollment period.

Frequently Asked Questions

Will I get a new Medicare card?

No. Your Medicare card and number stay the same when SSDI becomes retirement benefits. Request a replacement only if your card is lost, damaged, or incorrect.

What if I have Medicare Advantage or Part D?

Your Medicare Advantage or Part D coverage continues as it was. You can only change coverage during an available Medicare enrollment period.

What if I get both SSDI and SSI?

Your SSDI converts to retirement benefits at full retirement age, but SSI is separate. Your Medicare coverage continues.

How do I know when I’ll reach full retirement age?

Your full retirement age is 66 and some months or 67 depending on your birth year. Use this SSA chart to see when yours.

What if I’m weighing trying to get SSDI or taking early retirement?

It may be faster to get early retirement, but you will have a reduced payment for life. This article can help you decide if early retirement or SSDI is a better option in your situation.
