The Basic Steps to File for SSDI

To file for Social Security Disability Insurance, you submit a claim to the Social Security Administration (SSA) describing your medical condition and work history. The SSA reviews your medical records, work credits, and earnings history to decide whether your condition meets their definition of disability and whether you have worked long enough to be insured. The entire process typically takes three to six months for an initial decision, though many claims are denied on first review and require an appeal.

You can file in three ways: online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. Online filing is fastest and lets you save your process and return to it later. Phone filing takes about 15 minutes but you cannot save partway through. In-person filing at an office is useful if you need help understanding the questions or have documents to show.

Before you file, gather your Social Security number, birth certificate, proof of citizenship or legal residency, and medical records from any doctors who have treated your condition. You will also need your W-2 forms or tax returns from the past two years to show your work history. If you do not have all of these yet, you can still start your process — the SSA will ask you to send missing documents later.

Key Takeaways

  • You must have worked long enough and recently enough to have earned work credits; most people need 40 credits total, with 20 earned in the past 10 years.
  • Your medical condition must prevent you from working for at least 12 months or result in death; temporary or part-time disability does not may have access to.
  • Filing online at ssa.gov is faster than phone or in-person, and you can save your process and return to it later.
  • The SSA will request medical records directly from your doctors, but you can speed up the process by sending them yourself.
  • If your claim is denied, you have 60 days to file an appeal; most people who appeal with new medical evidence are eventually approved.

Work Credits and Recent Work Requirements

Social Security Disability Insurance is not a needs-based program — it is an insurance program you pay into through payroll taxes. To be insured for disability benefits, you must have earned enough work credits. You earn one credit for every $1,550 of wages you earn in a year (this amount changes annually). Most people need 40 credits total to be insured for SSDI, with at least 20 of those credits earned in the 10 years before you become disabled.

If you became disabled before age 24, you may need fewer credits — as few as 6 credits earned in the 3 years before disability. If you are between 24 and 31, you generally need credits equal to half the years between age 21 and the year you became disabled. The SSA can tell you exactly how many credits you have by looking at your Social Security record.

The "recent work" requirement means you must have worked recently enough that you still have credits in the bank. If you stopped working 15 years ago and have not worked since, you will not have the 20 credits earned in the past 10 years that SSDI requires. This is why SSDI is different from Supplemental Security Income (SSI), which has no work requirement — SSI is for people with very low income and assets, regardless of work history.

Medical Conditions That Meet SSDI's Definition of Disability

The SSA uses a strict definition of disability: your condition must prevent you from doing any substantial work for at least 12 consecutive months, or it must be expected to result in death. "Substantial work" means earning more than about $1,550 per month (this amount changes yearly). If you can work part-time or earn less than this amount, the SSA will likely deny your claim, even if you cannot work full-time.

The SSA maintains a list called the Blue Book that describes conditions it considers disabling. These include cancer, heart disease, severe arthritis, bipolar disorder, schizophrenia, intellectual disability, and many others. If your condition matches a Blue Book listing and your medical evidence supports it, approval is faster. If your condition does not match a listing, the SSA will still consider your claim, but the review takes longer and the bar is higher.

Common reasons claims are denied include: medical evidence that does not support the severity claimed, gaps in treatment (the SSA assumes you are not as sick if you have not seen a doctor in months), work activity that shows you can earn substantial income, or statements from your doctor that you could work part-time or with accommodations. The SSA weighs medical records more heavily than your own statements about your condition.

What Documents to Submit With Your Claim

When you file, the SSA will ask for your medical records, but you do not have to wait for them to request the records themselves. Sending your own copies speeds up the process by weeks. Gather records from every doctor, hospital, mental health provider, or specialist who has treated your condition in the past three to five years. Include test results, imaging reports, surgery notes, and medication lists.

You will also need to list your work history for the past 15 years, including job titles, employers, dates worked, and the type of work you did. The SSA uses this to understand what kind of work you have done and whether your condition prevents you from doing similar work. If you were self-employed, bring tax returns and profit-and-loss statements.

Bring proof of citizenship or legal residency (passport, birth certificate, or green card), your Social Security card or a document showing your number, and your driver's license or state ID. If you have been treated for substance abuse, bring records showing you have completed treatment or are in ongoing treatment — the SSA will not approve a claim based solely on drug or alcohol use, but it will consider how addiction has affected your ability to work.

The Timeline From Filing to Decision

After you file, the SSA sends your claim to a Disability information Services (DDS) office in your state. This office is staffed by disability examiners and medical consultants who review your file. They request medical records from your doctors, review what you submitted, and make a recommendation. This step typically takes 30 to 60 days, though it can take longer if your medical records are hard to obtain or if your case is complex.

Once the DDS completes its review, the SSA makes a final decision and sends you a letter. If approved, your benefits begin the month after you have been disabled for five full months (this is called the waiting period). If denied, the letter explains why and tells you how to appeal.

The entire process from filing to initial decision usually takes three to six months. However, if your condition is severe and your medical evidence is strong, some claims are approved faster — occasionally within two months. If your claim is denied and you appeal, the next step (called reconsideration) takes another two to four months. If reconsideration is also denied, you can request a hearing before an administrative law judge, which typically takes four to eight months to schedule.

What Happens If Your Claim Is Denied

About 65 percent of initial SSDI claims are denied. A denial does not mean you are ineligible — it often means the SSA needs more or better medical evidence, or that your work history does not meet the requirements. You have 60 days from the date on the denial letter to file an appeal. Do not wait; if you miss this important date, you have to file a new claim and start over.

The first appeal is called reconsideration. You submit new medical evidence, updated records from your doctors, or additional information about your work history. Many people are approved on reconsideration if they provide stronger medical documentation. If reconsideration is also denied, you can request a hearing before an administrative law judge (ALJ). At a hearing, you can present evidence and testify about your condition and work limitations. Approval rates at hearings are much higher than at the initial level — roughly 60 percent of cases that reach a hearing are approved.

If you are denied at the hearing level, you can appeal to the Appeals Council, and then to federal court. These later appeals are rare and usually require a lawyer. Many disability lawyers work on contingency, meaning they take a percentage of your back pay (usually 25 percent) only if you win. You can find a lawyer through the National Organization of Social Security Claimants' Representatives (NOSSCR) or through your state bar association.

How SSDI Affects Other Income and Benefits

SSDI does not have an income limit — you can have other income and still receive SSDI. However, if you work and earn more than the substantial gainful activity (SGA) amount (about $1,550 per month in 2024), the SSA may decide you are no longer disabled and stop your benefits. There are work incentives that let you test your ability to work without when ready losing benefits: the Trial Work Period lets you work for nine months without affecting your benefits, and the Extended may be able to access Period

Once you are approved for SSDI, you automatically become may be able to access for Medicare after 24 months of receiving benefits. This is true even if you are under 65. You do not have to be retired or meet any other condition — Medicare may be able to access is automatic. You will receive a Medicare card in the mail; you do not have to do anything to set up it.

SSDI benefits do not count as income for purposes of Medicaid or Supplemental Security Income (SSI). If you are receiving SSI and are approved for SSDI, your SSI will stop, but your Medicaid will usually continue (this varies by state). Some states have programs that let you keep Medicaid even after your income is too high for SSI — ask your state Medicaid office about this.

Frequently Asked Questions

Can I file for SSDI if I am still working?

Yes. You can file while working, and the SSA will review whether your condition prevents you from doing substantial work. However, if you are earning more than the SGA amount (roughly $1,550 per month), the SSA will likely deny your claim, reasoning that you are already doing substantial work. If you are earning less than SGA, you can file and explain why your condition limits your ability to work more.

Do I need a lawyer to file for SSDI?

No. You can file on your own without a lawyer. However, if your claim is denied and you appeal, a lawyer can significantly improve your chances. Many people hire a lawyer only after reconsideration is denied and they are preparing for a hearing. Lawyers are paid only if you win, and they take a percentage of your back pay.

What if I do not have medical records from my doctors?

Tell the SSA which doctors have treated you, and they will request the records. However, this slows down your case. If you have not seen a doctor in a long time, the SSA may assume your condition is not as severe as you claim. If you cannot afford medical care, tell the SSA this — some communities have free or low-cost clinics, and the SSA may help you find one.

How much will I receive in SSDI benefits?

Your benefit amount is based on your lifetime earnings record. The SSA calculates an average of your highest 35 years of earnings and converts that to a monthly benefit. The average SSDI benefit is around $1,550 per month, but it ranges from about $700 to over $3,800 depending on your work history. You can see an estimate of your benefit by creating a my Social Security account at ssa.gov.

Can I file for SSDI on behalf of someone else?

A parent or legal guardian can file for a child under 18, or for an adult who cannot manage their own affairs. You will need proof of guardianship or power of attorney. If you are filing for someone else, you can do it online, by phone, or in person at a Social Security office.
