You need a medical condition that stops you from working, a work history in Social Security–covered jobs, and approval from Social Security itself

Social Security Disability Insurance (SSDI) has three hard requirements. First, you must have a medical condition — physical or mental — that is expected to last at least 12 months or result in death, and that condition must prevent you from doing substantial work. Second, you must have worked in jobs where you and your employer paid Social Security taxes, and you must have earned enough credits to may have access to. Third, Social Security must review your medical records and decide your condition meets their definition of disability. There is no application you can submit that automatically puts you on the program.

The medical part is not about whether you feel too sick to work. It is about whether a doctor can document that your condition prevents you from doing any job that exists in the economy, not just your old job. The work history part means you cannot have spent your entire adult life outside the formal workforce. And the approval part means Social Security will ask for records from your doctors, hospitals, and any specialists you have seen — and they will make the final call, not your own doctor.

Key Takeaways

  • Your condition must be documented by medical records from a doctor, hospital, or specialist — Social Security will not take your word for it or rely only on your own doctor's opinion.
  • You must have worked in Social Security–covered employment and earned enough credits; generally this means working about five of the last ten years if you are under 62.
  • Social Security's definition of disability is stricter than most insurance companies use — your condition must prevent you from doing any substantial work, not just your previous job.
  • The approval process takes months and often requires a second medical review; most people are denied on the first submission and must request reconsideration.
  • You can work part-time while receiving SSDI as long as your earnings stay below a set limit, which changes yearly.

The Medical Condition Must Meet Social Security's Definition

Social Security uses a specific definition of disability that is narrower than what many people think. Your condition must be severe enough that it prevents you from doing any job available in the national economy — not just your old job, and not just jobs in your town. If Social Security decides you could do sedentary work, or work that does not require standing all day, they may deny you even if your previous job required physical labor.

Your condition must also be expected to last at least 12 months or be terminal. A broken leg that will heal in three months does not count. A back injury that might improve does not count unless medical records show it is not improving after treatment. Social Security looks at what your doctors have documented in writing — test results, imaging, treatment notes, specialist reports — not at what you tell them in a phone call or form.

Social Security maintains a list called the Blue Book that describes conditions they recognize as disabling. If your condition is on that list and your medical records match the criteria listed, approval is faster. If your condition is not on the list, Social Security must still consider it, but the process takes longer because they have to evaluate whether your specific case is as severe as conditions that are listed.

You Must Have Worked in Social Security–Covered Jobs and Earned Credits

Social Security is an insurance program, not a welfare program. To receive SSDI, you must have paid into the system through payroll taxes. Each year you work and pay Social Security taxes, you earn credits — in 2024, you earn one credit for each $1,730 in wages, up to four credits per year. The amount that earns a credit changes yearly.

How many credits you need depends on your age when you become disabled. If you are under 24, you generally need six credits earned in the three years before you became disabled. If you are 24 to 31, you need credits equal to the number of years from age 21 to the year you became disabled, with a minimum of six. If you are 31 or older, you generally need 40 credits total, with at least 20 earned in the ten years before you became disabled. This is why someone who worked steadily for five to ten years and then stopped working may still may have access to, but someone who never worked in covered employment cannot.

Self-employment counts, but you must have reported your income to the IRS and paid self-employment tax. Work done off the books, or work in certain government jobs that did not participate in Social Security, does not count toward your credits.

Social Security Will Request Medical Records and May Order a Consultative Exam

When you submit information to Social Security, they do not make a decision based on what you write. They request medical records from every doctor, hospital, clinic, and specialist you list. This process takes weeks. If your records are incomplete or do not clearly show your condition, Social Security may order a consultative exam — a one-time appointment with a doctor they choose and pay for. You do not choose this doctor, and the exam is usually brief.

Social Security also assigns your case to a disability examiner and a medical consultant (a doctor who works for Social Security, not your own doctor). These two people review all your records and decide whether your condition meets the definition of disability. They may deny you if they believe your condition is not as severe as you described, or if they believe you could still do some type of work.

This review takes two to four months on average. If Social Security needs more information, they will contact you or your doctor. If you do not respond to requests for records or information, they may deny you for failure to cooperate.

Most People Are Denied on First Submission and Must Request Reconsideration

Social Security denies roughly 65 to 70 percent of initial applications. This does not mean you are not disabled — it means Social Security did not find enough medical evidence in the records they received, or they decided your condition does not meet their definition. If you are denied, you have 60 days to request reconsideration, which sends your case to a different examiner and medical consultant for a fresh review.

At reconsideration, you can submit new medical records — for example, records from a recent hospitalization or new test results. You can also request a hearing before an administrative law judge if reconsideration is denied. The hearing is your chance to present your case in person or by phone, and to have a representative (often a disability lawyer) argue on your behalf. Hearings take several months to schedule, but they are where many people who were denied twice end up being approved.

Throughout this process, you can work part-time. Social Security allows you to earn up to a certain amount per month — in 2024, that limit is $1,550 — without it affecting your SSDI. If you earn more than that, your benefits may be reduced or stopped. The earnings limit changes yearly.

You Can Have a Representative Help You Through the Process

Many people hire a disability lawyer or non-lawyer representative to help them. These representatives can request your medical records, submit evidence, and represent you at a hearing. If you win your case, the representative is paid from your back pay (the money Social Security owes you from the date you became disabled to the date you were approved), not from your ongoing benefits. The fee is capped by law — currently 25 percent of back pay, or $7,200, whichever is less.

You do not have to hire a representative to apply, but many people find it helpful, especially if you have been denied once or twice. Some disability lawyers work on contingency, meaning they only get paid if you win. Others charge an hourly fee. You can find representatives through the National Organization of Social Security Claimants' Representatives (NOSSCR) or by asking a local legal aid office.

Work History and Medical Records Are Your Two Main Hurdles

The most common reasons Social Security denies people are: not enough work history or credits; medical records that do not clearly show a severe condition; or a condition that Social Security believes allows some type of work. If you have worked steadily for at least five years, you likely have enough credits. If you have not worked much, you may not may have access to no matter how severe your condition is.

If you have worked enough but your medical records are thin — for example, you have only seen a doctor once or twice — Social Security may deny you because they do not have enough evidence. Before you apply, gather records from every doctor and hospital you have visited. If you have not seen a doctor in a long time but your condition is severe, seeing a doctor and getting documented treatment will strengthen your case significantly.

Frequently Asked Questions

Can I work while receiving SSDI?

Yes. You can earn up to a monthly limit (currently $1,550 in 2024) without losing benefits. Above that amount, your benefits are reduced. After nine months of work above the limit, your benefits stop, but you enter a nine-month trial work period where you can test your ability to work without losing coverage. The earnings limit changes yearly.

What if I have not worked in several years?

You may not have enough credits to may have access to. Social Security looks at whether you earned credits in the years before you became disabled. If you stopped working ten years ago and have not worked since, you likely do not meet the work history requirement, even if you worked steadily before that.

How long does it take to get approved?

Initial review takes two to four months. If denied, reconsideration takes another two to four months. A hearing before a judge takes four to six months to schedule after you request it. Some people are approved at initial review; many are not approved until after a hearing, which can be 12 to 18 months after they first applied.

Do I need a lawyer to apply?

No, but many people find representation helpful, especially after being denied once. Lawyers are paid only if you win, and only from your back pay. You can apply on your own by going to ssa.gov or visiting your local Social Security office in person.

What happens if my condition improves?

Social Security can review your case and decide you are no longer disabled. They do this through a continuing disability review, which happens at intervals depending on how likely your condition is to improve. If your condition does improve and you return to work, you enter a work incentive period where you keep your benefits for a time while you test your ability to work.
