SSDI Waiting Periods: When Medicare Starts and What Can Help Before Then

1Do you get paid for the 5 month waiting period?

No benefit is paid for the waiting months. SSA says you must wait 5 full calendar months from the date it finds your disability began before your entitlement can begin, so entitlement begins in the sixth full month. (SSA, Approval Process) The waiting period begins the first full month after the date SSA decides your disability began. (SSA, How To Apply)

SSA's own example: "Your disability began on June 15, 2023 and you applied on July 1, 2023. If approved, you are entitled to benefit payments beginning the month of December 2023, your sixth full month of disability." SSA also says, "We pay SSDI benefits in the month following the month for which they are due," so the December benefit in that example is paid in January. (SSA, Approval Process)

The exception is ALS: "there is no waiting period if your disability results from amyotrophic lateral sclerosis (ALS) and you are approved for SSDI benefits on or after July 23, 2020." (SSA, Approval Process) (SSA, Waiting period FAQ)

2When does Medicare start if you are on SSDI?

SSA says: "We automatically enroll you in Original Medicare (Parts A and B) after you get disability benefits for 2 years." (SSA, Approval Process) SSA's operations manual puts the start at "the first day of the person's 25th month of disability benefit entitlement," and counts all months of entitlement toward the 24, "even though a cash benefit may not be payable for a particular month." (SSA POMS HI 00801.146) SSA says information about Medicare comes several months before your coverage starts. (SSA Publication 05-10153)

For Part A, hospital insurance, SSA says "It's provided at no cost to you." For Part B, medical insurance, "You will need to pay a monthly premium if you want this coverage." (SSA, Approval Process)

Two groups wait less. With ALS, "Medicare coverage begins sooner, generally the first month you are eligible for disability benefits." (SSA, Approval Process) With permanent kidney failure requiring regular dialysis or a transplant, or ALS, "you may qualify for Medicare almost immediately." (SSA Publication 05-10153)

3Who can get SSDI, and how much can you earn?

SSA looks at two things. First, "You must have a disability that affects your ability to work for a year or more, or will result in death." Second, work history: "Generally, you must have worked for at least 5 of the last 10 years to qualify for Disability. People under the age of 24 may not need to have worked as long." (SSA, Who can get Disability)

If you keep working, your condition must also keep you from earning more than an amount SSA calls substantial gainful activity (SGA). SSA uses different rules for people who are self-employed. (SSA, Who can get Disability)

The blind SGA amount does not apply to SSI. (SSA, Substantial Gainful Activity) How much SSDI pays depends on you: "Your payment amount is based on your work history before your disability began." (SSA, Disability) SSA says you can get an estimate from your Social Security Statement in a personal my Social Security account or from its Benefit Calculators. (SSA, Approval Process) This page gives no average payment because each amount is individual.

4What can help with health costs before Medicare starts?

Medicaid is the main option, and your state runs it. HealthCare.gov says: "Even if you don't think you'll qualify for Medicaid based on your income, you should apply. You might qualify for your state's program, especially if you have children, are pregnant, or have a disability. You can apply for Medicaid and CHIP any time of year." (HealthCare.gov, Medicaid and CHIP)

If your income and resources are limited, SSI may also be an option. SSA says SSI provides monthly payments to people who are blind or have a disability, and "If you get SSI, you also may be able to get other benefits, such as Medicaid and the Supplemental Nutrition Assistance Program (SNAP)." (SSA Publication 05-10153)

For state limits and how to apply, see Medicaid Income Limits Explained, or the pages for Texas, Indiana, Kentucky, Minnesota Medical Assistance, and MassHealth.

5How does SNAP treat a household member with a disability?

Once you get SSDI, SNAP treats you as a household member with a disability. The federal definition includes anyone who "Receives supplemental security income benefits under title XVI of the Social Security Act or disability or blindness payments under titles I, II, X, XIV, or XVI." SSDI is paid under title II. (7 CFR 271.2)

That changes three rules for your household: (7 CFR 273.9)

• Households with an elderly or disabled member only have to meet the net income test, not the gross income test.
• Medical expenses above $35 a month for the member with a disability can be deducted (an official threshold). Allowable costs include prescription drugs, health insurance premiums, and Medicare premiums.
• The cap on the shelter deduction applies only if the household does not contain an elderly or disabled member.

SSDI itself counts as unearned income, because SNAP rules list "disability benefits" and "social security benefits" as unearned income. (7 CFR 273.9) Because the definition turns on receiving the payments, ask your SNAP office how your household is classified while your claim is pending. For limits by state, see Texas, Indiana, Kentucky, Massachusetts, and Minnesota SNAP. For other states and the national table, see SNAP income limits by household size.

6Once Medicare starts, can you get help paying for it?

Possibly. SSA says: "If you get Medicare and have low-income and few resources, your state may pay your Medicare premiums and, in some cases, other Medicare costs for which you are normally responsible, such as deductibles and coinsurance." SSA adds that only your state can decide who gets this help, and it points you to your state or local welfare office or Medicaid agency. (SSA, Approval Process)

For drug costs, SSA says that if you receive Medicare and have limited resources and income, "you may be eligible for Extra Help with Medicare Prescription Drug Plan Costs." (SSA, Approval Process) See Medicare Savings Programs: 2026 Income Limits and Medicare Extra Help for the limits.

7How do you apply for SSDI?

1. Check your work history. SSA says to sign in and look under "More Benefits" to see if you have worked long enough. (SSA, Who can get Disability)
2. Get ready with SSA's Disability Starter Kit, which lists the documents and information SSA will ask for. (SSA, How To Apply)
3. Apply online, or call 1-800-772-1213 between 8:00 a.m. and 7:00 p.m. (TTY 1-800-325-0778). SSA representatives can make an appointment for you to apply. (SSA, How To Apply)
4. Read your decision letter. If you disagree, your appeal "must be in writing and received within 60 days of the date you receive the letter containing our decision." (SSA Publication 05-10153)

You submit your application yourself on the official site. Benefit Bull is free and never files for you.
