When a disability ends your working life, your job-based health plan usually ends soon after. Medicare is coming, but it usually doesn't start until about two and a half years after your disability began. This page covers the coverage you can use in between: COBRA, your state's continuation rules, a Marketplace plan, and Medicaid. It also covers how to hand off to Medicare without a gap. For the full picture, see our guide to Medicare under 65 on disability.
How long do I need coverage before Medicare starts?
Usually about 29 to 30 months from when your disability began. Social Security Disability Insurance (SSDI) has a 5-month waiting period, and Medicare starts in your 25th month of SSDI benefits. Your Social Security award letter shows the dates. We explain the timing step by step in do you automatically get Medicare on disability.
With ALS, Medicare starts as soon as SSDI does, so the gap is much shorter. With kidney failure (ESRD), Medicare can start around the fourth month of dialysis once you sign up.
Who pays for health insurance while I'm on long-term disability?
Usually you do, through COBRA, a Marketplace plan or Medicaid. A long-term disability (LTD) policy replaces part of your pay. It is not health insurance. Some employers keep health coverage going for a while during a disability leave, but that depends entirely on your employer's plan rules. Ask HR for the plan documents and the exact date your coverage ends, in writing.
Can I keep my job's health plan with COBRA?
If your employer had 20 or more employees, yes, usually for 18 months, and possibly 29 months because of your disability. COBRA lets you keep the same group plan, but you pay the full cost yourself, up to 102% of what the plan costs. You have at least 60 days to elect it, counted from the later of the day your coverage ends or the day you get the COBRA notice.
The 29-month disability extension
This rule matters here, because SSDI's 5-month wait plus 24 months is about 29 months. COBRA can stretch from 18 to 29 months if all of these are true:
- Your COBRA came from losing your job or having your hours cut.
- Social Security finds you were disabled at some point during your first 60 days of COBRA. The decision itself can come later.
- You tell the plan within 60 days of Social Security's decision and before your first 18 months run out.
The extension covers everyone in your family who is on the plan. During the extra 11 months, the plan can charge up to 150% of its cost for months that include the disabled person. Because of the 60-day notice rule, send the plan a copy of your award letter as soon as it arrives. See what COBRA is and how it works.
What if my employer has fewer than 20 employees?
Federal COBRA usually doesn't apply, but your state's continuation law ("mini-COBRA") may. In North Carolina and South Carolina these laws cover insured group plans, not self-insured ones, and the coverage is much shorter in South Carolina and Tennessee.
| State | State continuation rule |
|---|---|
| North Carolina | Up to 18 months if you were covered for the 3 months before your coverage ended. You have at least 60 days to elect it, and the premium can be up to 102% of the group rate. It doesn't have to include prescription drug, dental or vision benefits. |
| South Carolina | The rest of the month plus 6 months, if you were covered for at least 6 months. You pay the full group premium. It is not available to anyone eligible for Medicare. |
| Tennessee | The rest of the month plus 3 months, if you were covered for the 3 full months before your coverage ended. You pay the full group premium. |
Because state continuation is short in South Carolina and Tennessee, you'll likely need a Marketplace plan or Medicaid for the rest of the wait if you live there.
Can I get a Marketplace plan while I'm on disability?
Yes. Losing job-based coverage opens a Special Enrollment Period, and your savings depend on your household income, including SSDI. North Carolina, South Carolina and Tennessee all use HealthCare.gov.
- Timing. You can enroll from 60 days before to 60 days after you lose job-based coverage. When COBRA runs out, you get another 60 days.
- Switching from COBRA. Voluntarily dropping COBRA, or stopping payments, doesn't qualify you for a Special Enrollment Period. Outside Open Enrollment, you generally wait until COBRA ends. So compare both before you elect COBRA.
- Income. HealthCare.gov counts both taxable and non-taxable Social Security, including SSDI. SSI does not count. Savings are based on your income compared with the federal poverty level.
We compare the two side by side in COBRA vs. Marketplace, and explain the enrollment window in Special Enrollment Periods for health insurance.
Can I get Medicaid while I wait for Medicare?
It depends heavily on your state.
- North Carolina expanded Medicaid to adults 19 to 64 with income up to 138% of the federal poverty level. If your income qualifies, that can be your bridge to Medicare. People on SSDI or SSI are exempt from the work requirements NC begins on January 1, 2027. Expansion coverage ends once you have Medicare. See whether you qualify for Medicaid in NC.
- South Carolina has not expanded Medicaid. Disability-related groups include Aged, Blind or Disabled coverage up to 100% of the poverty level and a Working Disabled program.
- Tennessee has not expanded Medicaid. TennCare for adults with disabilities generally comes through SSI, SSI-related groups or long-term care programs.
In all three states, people who get SSI generally get Medicaid automatically. For the differences, see Medicaid vs. Marketplace.
How do I switch to Medicare without a gap or overlap?
Know your Medicare start date, then plan exactly how your bridge coverage ends. In order:
- Confirm your Medicare start date from your award letter or Medicare card. The card arrives about 3 months before.
- Marketplace plan: it doesn't end on its own. Report your Medicare start date (up to 3 months ahead) so it ends the day before. Once you have Medicare, you lose premium tax credits on a Marketplace plan.
- COBRA: if Medicare starts after you elected COBRA, the plan is allowed to end your COBRA then. Confirm with the plan what happens to anyone else in your family on it.
- Medicaid in North Carolina: expansion coverage ends once you have Medicare. Ask whether you qualify for help with Medicare costs instead. See help paying for Medicare.
- Part B and drug coverage: Part B is set up for you. Whether you can delay Part B without a late-enrollment penalty depends on your specific situation, including whether you have group health coverage based on your own or your spouse's current employment. Employer size can also affect how Medicare coordinates with that coverage, so we check the details before you decide. Medicare.gov notes that COBRA isn't considered group health plan coverage for that purpose. Choose drug coverage during your 7-month window.
Mistakes we see people make
- Letting the 60-day COBRA election window pass while dealing with the disability claim.
- Missing the 60-day notice for the 29-month extension after Social Security approves SSDI.
- Dropping COBRA mid-year to save money, then finding there's no Special Enrollment Period for a Marketplace plan.
- Leaving SSDI off the Marketplace application. It counts as income, so your savings estimate will be wrong without it.
- Assuming the LTD policy covers health insurance.
- Keeping a Marketplace plan after Medicare starts without reporting it.

Frequently asked questions
Can I keep COBRA after my Medicare starts?
If Medicare starts after you elected COBRA, the plan is allowed to end your COBRA at that point. If you already had Medicare when you elected COBRA, the plan can't end it because of Medicare. Check with the plan before you drop anything.
Does SSDI count as income for Marketplace savings?
Yes. HealthCare.gov counts both the taxable and non-taxable parts of Social Security, including SSDI. SSI does not count.
Can I drop COBRA and switch to a Marketplace plan?
Not mid-year just because you want to. Voluntarily dropping COBRA doesn't open a Special Enrollment Period. You can switch during Open Enrollment, or within 60 days after COBRA runs out.
Does the COBRA disability extension cover my spouse and children?
Yes. When the 29-month extension applies, it covers every family member who is on the plan, not only the person with the disability.
Is there a "mini-COBRA" for small employers in the Carolinas and Tennessee?
Yes, for insured group plans. North Carolina allows up to 18 months, South Carolina the rest of the month plus 6 months, and Tennessee the rest of the month plus 3 months, each with its own eligibility rules.
