Disability āŗ Medicare and Medicaid
When does Medicare start on disability, and what covers me until then?
For anyone approved for SSDI or SSI, or waiting to be. By the end you’ll know your Medicare start date, how to get coverage during the wait, how SSI connects to Medicaid, and where to get help with Medicare costs.
With SSDI, Medicare starts automatically in your 25th month of disability benefits, about 29 months after your disability began. People with ALS get Medicare as soon as their disability benefits start. While you wait, Medicaid may cover you. If you get SSI, most states give you Medicaid automatically.
When does Medicare start with SSDI?
Two waits stack up. First, SSDI generally has a 5-month waiting period: your first check is for the sixth full month after SSA finds your disability began. Then Medicare comes after you have been entitled to SSDI for 24 months. Coverage starts in month 25.
| Step | When |
|---|---|
| Your disability begins | Month 0 |
| SSDI waiting period | 5 full months |
| SSDI benefits begin | About month 6 |
| Medicare Part A and Part B start automatically | Your 25th month of SSDI, about month 29 |
ALS: there is no 24-month wait for Medicare, and for applications approved since July 23, 2020, no 5-month wait for SSDI either.
Kidney failure: Medicare has separate rules, and you must sign up. With dialysis, coverage usually starts on the first day of the fourth month of treatment. See Medicare.gov on kidney failure.
What covers me while I wait?
Medicaid, the health coverage run by each state, is the main option. In states that cover adults under the expansion group, people 19 to 64 who don’t have Medicare can qualify based on income, with no savings test. Not every state covers this group. If your income is too high, ask about your state’s other programs for people with disabilities. Find your state’s rules.
- Apply early. For applications made on or after January 1, 2027, Medicaid will pay bills from only 1 or 2 months before the month you apply, depending on how you qualify. Today it is 3 months.
- Work rules. In states that cover the expansion group, most must start work rules for adults 19 to 64 by January 1, 2027. People with Medicare don’t have to meet them. The law also excludes people who are “medically frail,” which includes anyone who is “blind or disabled” under the Social Security Act’s SSI definition. Neither the law nor CMS’s rule says that getting SSDI counts automatically. If you are approved for SSDI, tell your state Medicaid office and ask whether you are excluded. See Medicaid work rules.
The Marketplace. If Medicaid turns you down, HealthCare.gov says you may be able to buy a private plan through the Health Insurance Marketplace while you wait for Medicare, and you may qualify for lower costs based on your income and household size. Include your SSDI income on the application. Once Medicare starts, you can’t use a Marketplace plan to replace or add to it. Start at HealthCare.gov’s page for people on SSDI.
COBRA from a former job. COBRA lets you keep a former employer’s health plan, usually at your own cost, for up to 18 months after you lose your job or your hours are cut. If SSA finds that your disability began before your 60th day of COBRA, and you stay disabled through the first 18 months, you and your covered family can keep COBRA for 11 more months, up to 29 months in all. That can carry you close to Medicare. You must send the plan a copy of SSA’s decision by the plan’s deadline, which can’t be shorter than 60 days. During the extra months, the plan can charge up to 150% of the premium.
If you are on COBRA when your SSDI approval arrives, send the plan a copy of the letter right away and ask for the disability extension in writing.

What happens to my Medicaid when Medicare starts?
Expansion Medicaid is only for people without Medicare. Before your state ends your Medicaid, it must check whether you qualify another way, including the programs that help pay Medicare costs. If you keep both, Medicare pays first and Medicaid fills in the difference.
When your SSDI award letter arrives, count forward to your 25th month of benefits and mark it. A few months before, call your state Medicaid office and ask what will change.
Does SSI come with Medicaid?
In most states, yes. It depends on which of three groups your state is in. These lists come from SSA’s program manual, revised September 30, 2026.
| Your state | What happens |
|---|---|
| Automatic states: the District of Columbia and the 34 states not listed below | SSA’s SSI approval also decides your Medicaid. No separate application. |
| Separate-application states: Alaska, Idaho, Kansas, Nebraska, Nevada, Oklahoma, Oregon, Utah (and the Northern Mariana Islands) | The state uses SSI’s rules, but you apply to the state Medicaid office separately. |
| Own-rules states: Connecticut, Hawaii, Illinois, Minnesota, Missouri, New Hampshire, North Dakota, Virginia | The state sets its own Medicaid rules for people on SSI. Contact your state Medicaid office. |
SSA’s names for these are 1634 states, SSI-criteria states and 209(b) states. If you get SSI, you also qualify automatically for Extra Help, which lowers Medicare drug costs.
Where can I get help paying Medicare costs?
Medicare has costs. The standard Part B premium is $202.90 a month in 2026. The 2027 amount has not been announced yet. State programs called Medicare Savings Programs can pay some or all of these costs. Two matter most here:
- QMB (Qualified Medicare Beneficiary) pays Part A and Part B premiums, deductibles and copays. In 2026, the limits are $1,350 a month in income for one person ($1,824 for a couple) and $9,950 in savings ($14,910 for a couple). Your state may allow higher amounts.
- QDWI (Qualified Disabled and Working Individual) pays the Part A premium for people who lost SSDI and premium-free Part A because they went back to work. In 2026, the limits are $5,405 a month in income ($7,299 for a couple) and $4,000 in savings ($6,000 for a couple).
The other two, SLMB (Specified Low-Income Medicare Beneficiary) and QI (Qualifying Individual), pay the Part B premium for people with somewhat higher incomes.
Working doesn’t end Medicare quickly. If SSDI stops because of work but you are still disabled, premium-free Part A continues for at least 93 months after your trial work period. See working on disability and help paying Medicare costs.
