What disability benefits are and who administers them
Disability benefits in the United States come from two main federal programs: Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI). Both are run by the Social Security Administration. SSDI is based on your work history and the taxes you paid into Social Security. SSI is a needs-based program for people with limited income and resources, regardless of work history. Understanding which program you might be looking at is the first step, because the rules, payment amounts, and what you can do while receiving benefits differ between them.
Beyond these two, some people receive disability payments through Veterans Benefits (if you served in the military), workers' compensation (if your disability came from a work injury), or state-run programs. This article focuses on SSDI and SSI because they are the largest federal disability programs and the ones most people encounter first.
Key Takeaways
- SSDI is based on your work record and Social Security taxes you paid; SSI is based on financial need and has no work requirement.
- Both programs require that a doctor document your condition meets the Social Security Administration's definition of disability, which is stricter than most people's everyday use of the word.
- You can work while on SSDI under specific rules called work incentives, and your benefits do not stop automatically if you earn money.
- Medicare and Medicaid coverage work differently under SSDI and SSI, and understanding the difference matters for your healthcare costs.
- The initial decision on your case usually takes three to six months, and most first applications are denied; requesting reconsideration or appealing is a normal next step.
How the Social Security Administration defines disability
The Social Security Administration uses a specific legal definition of disability that is narrower than how the word is used in everyday life. To be found disabled under either SSDI or SSI, you must have a medical condition (or combination of conditions) that prevents you from doing any substantial work, and that condition must be expected to last at least 12 months or result in death. This is a high bar. Having a condition that makes work difficult, or that limits what kind of work you can do, is not the same as meeting this definition.
The agency publishes a list called the Blue Book that describes conditions it recognizes as disabling. If your condition is on the list and your medical records show you meet the specific criteria for that condition, your case moves faster. If your condition is not on the list, the Social Security Administration can still find you disabled, but it requires more detailed medical evidence and takes longer. Your doctor's opinion matters, but the final decision rests with a Social Security examiner or judge who reviews your medical records, not your doctor alone.
The difference between SSDI and SSI
Many people are confused about which program they might receive because the names sound similar and both come from Social Security. The clearest way to think about it: SSDI is an insurance program (you paid in, so you get benefits), while SSI is a welfare program (you need help, so you get benefits). You can receive both at the same time if you meet the rules for each, though your SSDI payment is usually reduced by the SSI amount.
The table below shows the main differences. SSDI payment amounts are based on your earnings record and average around $1,550 per month in 2024, though individual amounts vary widely. SSI has a federal base rate of $943 per month in 2024, and some states add additional payments on top. The work incentives available to you depend heavily on which program you are on — SSDI offers much more flexibility to work and keep benefits than SSI does.
| Feature | SSDI | SSI |
|---|---|---|
| Based on | Your work history and Social Security taxes paid | Financial need; no work history required |
| Who can get it | People who worked and paid into Social Security | People with limited income and resources (under $2,000 in countable resources for individuals) |
| Payment amount | Based on your earnings record; average about $1,550 per month in 2024 | Federal base rate of $943 per month in 2024; some states add more |
| Healthcare coverage | Medicare after 24 months on SSDI | Medicaid, usually right away |
| Work incentives | Can work and keep benefits under specific rules | Limited work incentives; earnings reduce benefits quickly |
What happens after you submit information to Social Security
After you submit your process or information to Social Security, a disability examiner is assigned to your case. That examiner requests your medical records from your doctors, hospitals, and any mental health providers you have seen. This process takes time — Social Security must contact each provider, and providers are not always fast in responding. You can speed this up by getting your own medical records and sending them to Social Security yourself.
The examiner reviews your medical records against the Blue Book criteria and decides whether your condition meets the definition of disability. If the examiner needs more information, they may ask you to see a doctor that Social Security pays for (called a consultative examination). This is free to you. The examiner then writes a decision letter explaining why you were approved or denied. Most first applications are denied. If you are denied, you have the right to request reconsideration (a second look by a different examiner) or to appeal to an administrative law judge. Many people who are denied the first time are approved on appeal.
Working while on SSDI and work incentives
One of the biggest misconceptions about SSDI is that you cannot work at all. That is not true. SSDI has built-in work incentives designed to let you test whether you can return to work without losing your benefits when ready. The most important ones are the Trial Work Period and Extended may be able to access.
During your Trial Work Period, you can earn any amount of money and keep your full SSDI benefit for nine months (not necessarily consecutive). After the Trial Work Period ends, there is a 36-month Extended may be able to access period during which your benefits stop only if your earnings exceed a certain amount (called Substantial Gainful Activity, or SGA, which is $1,550 per month in 2024, though this amount changes yearly). If your earnings drop below SGA, your benefits restart automatically without a new process. After Extended may be able to access ends, your benefits stop if you earn over SGA, but you can restart them within five years without reapplying if your earnings drop again.
SSI has fewer work incentives. You can earn some money — the first $65 per month plus half of earnings above that are not counted against your benefit — but your SSI payment reduces quickly as you earn more. Work incentives exist under SSI too (like Plans to Achieve Self-Support), but they are more complex and require advance planning with Social Security.
Healthcare coverage under SSDI and SSI
Healthcare coverage is one of the biggest practical differences between the two programs. If you are on SSDI, you become covered by Medicare automatically after you have been on SSDI for 24 months. Medicare is federal health insurance with three parts: Part A (hospital), Part B (doctor visits), and Part D (prescription drugs). You pay premiums for Parts B and D, though if your income is low, you may may have access to for help paying them. Many people on SSDI also may have access to for Medicaid to help cover costs Medicare does not pay.
If you are on SSI, you are usually covered by Medicaid right away. Medicaid is a joint federal-state program, so coverage and rules vary by state. Some states are more generous than others. Unlike Medicare, Medicaid does not have premiums, but it does have limits on which doctors and hospitals you can use in some states. If you are on both SSDI and SSI, you get both Medicare and Medicaid.
What to do if your process is denied
A denial letter from Social Security is not the end of the process. You have the right to request reconsideration within 60 days of the denial. Reconsideration means a different examiner looks at your case from the start. You can submit new medical records or other evidence at this stage. Many people do not request reconsideration because they think it is pointless, but statistics show that a meaningful number of cases approved on reconsideration would have stayed denied without it.
If reconsideration is also denied, you can request a hearing before an administrative law judge. This is a formal appeal, and you can bring a representative (a lawyer or non-lawyer advocate) to help you. The judge reviews your entire case and can approve you even if two examiners denied you. The hearing process takes longer — usually six months to a year — but approval rates at the hearing level are significantly higher than at the initial or reconsideration level. You do not need a lawyer to appeal, but having one or a may have access to representative increases your chances.
Frequently Asked Questions
Can I get disability benefits if I have never worked?
You cannot get SSDI without a work history, because SSDI is based on Social Security taxes you paid. You may be able to get SSI if you have limited income and resources, regardless of work history. SSI is available to disabled people of any age, including children, as long as the financial and medical requirements are met.
How long does it take to get a decision on my case?
Initial decisions usually take three to six months, depending on how quickly your doctors send records and how complex your case is. Reconsideration takes another three to six months. A hearing before a judge can take six months to over a year. You can receive back pay (benefits from the month you applied) if you are eventually approved, even if approval takes a long time.
What if I disagree with the doctor Social Security sends me to see?
You can see your own doctor and submit those records instead. Social Security will consider medical evidence from any source. The consultative examination is free and is meant to fill gaps in your medical record, not to replace your own doctor's opinion. You have the right to request a different doctor if you have a strong reason, though Social Security does not always grant this request.
Will my benefits stop if I get married or move in with someone?
SSDI benefits are based on your own disability and work record, so marriage or living with someone does not affect your SSDI. SSI is different — it is needs-based, so your benefit may change if you marry or live with someone whose income or resources count toward yours. The rules are complex and depend on your state, so contact Social Security directly if this applies to you.
Can I work part-time and still get disability benefits?
Yes, under SSDI's work incentives. You can work part-time during your Trial Work Period and keep your full benefit. After that, your benefit continues as long as your earnings stay below the SGA amount. SSI allows some work, but your benefit reduces as you earn more. The exact amount you can earn depends on which program you are on and which work incentive you use.
