What SSDI actually requires from you

Social Security looks at three things to decide whether you meet SSDI requirements: you must have a medical condition that meets their definition of disability, you must have worked long enough to build up work credits, and you must not be earning more than a set amount each month. You arrived here from the work credits section, so you already know that part. This page covers the medical piece — what "disability" means to Social Security, and what you have to show them.

The medical requirement is the one that trips up most people. Social Security does not pay for conditions that are inconvenient or painful or make work harder. They pay only for conditions expected to last at least 12 months or result in death, and only if the condition prevents you from doing any substantial work. That is a high bar. You cannot earn more than $1,550 per month (in 2024; this amount changes yearly) while on SSDI, and Social Security will ask for medical records, test results, and statements from your doctors before they decide.

Key Takeaways

  • Social Security requires that your condition prevent you from doing any substantial work, not just your current job, and that it last at least 12 months or result in death.
  • You must submit medical evidence — records from your doctors, results from tests and imaging, and statements about what you can and cannot do physically or mentally.
  • Social Security has a list called the Blue Book that describes conditions they recognize as disabling; if your condition is on it and your medical records match, approval is faster.
  • You cannot earn more than $1,550 per month (2024 amount) while receiving SSDI, and Social Security will verify your work history and income before paying you.
  • The decision process usually takes three to five months, though it can take longer if Social Security needs more medical information from your doctors.

The medical definition Social Security uses

Social Security has a specific definition of disability that is narrower than most people think. Your condition must be severe enough that it prevents you from doing any substantial work — not just your current job, but any job you could reasonably do given your age, education, and work history. The condition must also be expected to last at least 12 months or result in death. If you have a condition that will improve within a year, Social Security will not pay.

This is why someone with a broken leg might not meet the requirement even though they cannot work right now. If the leg will heal within 12 months, Social Security will deny the claim. The same applies to many mental health conditions, back injuries, and other conditions that improve with time or treatment. Social Security is betting on your recovery, not your current state.

Social Security also looks at whether you are following treatment. If your doctor recommends surgery or medication and you refuse it without a good reason, Social Security may deny your claim or stop your benefits. They assume that if you followed the treatment, you might be able to work. This rule has exceptions — you do not have to have surgery if it carries serious risks, for example — but you need to be able to explain why you are not following your doctor's information.

How to show Social Security your condition is disabling

Social Security will not take your word for it. You must submit medical evidence that documents your condition and shows how it limits what you can do. The strongest evidence comes from your own doctors — the ones who have examined you, run tests, and treated you over time. Bring records from every doctor you have seen in the past few years, including primary care, specialists, mental health providers, and emergency room visits.

The records should include the results of tests and imaging — blood work, X-rays, MRIs, CT scans, EKGs, and anything else that shows what is wrong. They should also include your doctor's notes about your symptoms, how often you have them, and how they affect your daily life. A one-line note saying "patient reports back pain" is much weaker than a detailed note describing the pain, what makes it worse, what treatments have been tried, and whether the pain limits your ability to sit, stand, or lift.

If you do not have recent medical records, you will need to see a doctor before you explore. Social Security cannot make a decision without medical evidence, and the longer you wait to gather it, the longer the process takes. If you cannot afford a doctor, look for a community health center or free clinic in your area — Social Security will accept records from any licensed medical provider.

The Blue Book and conditions Social Security recognizes

Social Security publishes a list called the Blue Book that describes conditions they recognize as disabling. The list includes categories like cancer, heart disease, diabetes, arthritis, mental disorders, neurological conditions, and many others. Each category has specific medical findings that Social Security looks for — for example, if you have cancer, they want to see pathology reports and imaging showing the cancer and its stage.

If your condition is on the Blue Book and your medical records match what Social Security is looking for, the approval process is usually faster. Social Security calls this meeting a "listing." You do not have to meet a listing to be approved — you can be approved even if your condition is not on the list or does not match the listing exactly — but meeting a listing makes approval more likely and faster.

You can read the Blue Book yourself on the Social Security website. Search for your condition and see what medical findings Social Security expects. Then gather records that show you have those findings. If your records do not match the listing, do not give up — you can still be approved through a different route called "medical-vocational allowance," which looks at your age, education, work history, and how your condition affects your ability to work. This route takes longer and is less predictable, but it is how many people are approved.

Work history and income limits

Even if your medical condition meets Social Security's definition of disability, you must also have enough work credits. You arrived here from the work credits section, so you know the basic rule: you need 40 credits, with 20 of them earned in the 10 years before you became disabled. The exact number can be lower if you became disabled before age 24, and it can be higher if you are older. Social Security will tell you how many credits you need when you explore.

You also cannot earn more than $1,550 per month (in 2024) while receiving SSDI. This is called "substantial gainful activity," or SGA. If you earn more than this amount, Social Security will assume you are able to work and will deny your claim or stop your benefits. The $1,550 amount changes every year, so check the Social Security website for the current year's limit. If you are blind, the limit is higher — $2,590 in 2024.

Social Security counts only earned income — money you make from working. They do not count retirement savings, disability insurance from a private policy, unemployment benefits, or money from family members. If you are self-employed, Social Security looks at your net profit, not your gross revenue. Keep careful records of what you earn and what you spend on your business, because Social Security will ask for tax returns and business records.

What happens after you submit your medical evidence

Once you submit your claim with your medical records, Social Security sends your file to a disability examiner and a medical consultant. They review your records, check your work history, and decide whether you meet the requirements. This usually takes three to five months, though it can take longer if Social Security needs more information from your doctors.

If Social Security needs more records, they will contact your doctors directly and ask them to send additional information. You can speed this up by calling your doctors yourself and asking them to send the records to Social Security. Give them the Social Security claim number so they know which file to send to. If your doctors are slow to respond, Social Security may make a decision based on what they have, which could be a denial if the records are incomplete.

Social Security will send you a letter with their decision. If they approve you, the letter will say when your benefits start and how much you will receive each month. If they deny you, the letter will explain why and tell you how to appeal. You have 60 days from the date on the letter to file an appeal. Many people are denied the first time and approved on appeal, so do not give up if you get a denial.

Frequently Asked Questions

Do I have to be unable to work at all to get SSDI?

Yes. Social Security requires that your condition prevent you from doing any substantial work, not just your current job. If Social Security thinks you could do a different job — even one that pays less or is less skilled — they may deny your claim. This is why age and education matter: a 60-year-old with a high school diploma has fewer job options than a 30-year-old with a college degree, so Social Security may approve the older person even with the same medical condition.

What if my doctor says I cannot work but Social Security denies me?

Your doctor's opinion matters, but it is not the only thing Social Security considers. Social Security weighs your doctor's statement against your medical records, your work history, your age, and your education. If your medical records do not support what your doctor says, or if Social Security thinks you could do a different type of work, they may deny you even with your doctor's support. You can appeal and ask your doctor to write a more detailed statement explaining how your condition limits your ability to work.

Can I get SSDI while I am still working?

No. If you are earning more than $1,550 per month (2024 amount), Social Security will assume you are able to work and will deny your claim or stop your benefits. You can earn less than this amount and still receive SSDI, but once you cross the limit, your benefits stop. There is a trial work period that lets you test your ability to work without losing benefits when ready, but that comes after you are already approved.

How long does it take to get a decision on my SSDI claim?

Most decisions take three to five months. If Social Security needs more medical records from your doctors, it can take longer — sometimes six months or more. You can call Social Security to check on your claim, but calling does not speed up the process. The best thing you can do is make sure your doctors send all the records Social Security asks for as quickly as possible.

What if I do not have recent medical records?

You will need to see a doctor and get recent records before Social Security can make a decision. Look for a community health center or free clinic if you cannot afford a private doctor. Social Security will accept records from any licensed medical provider, including nurse practitioners and physician assistants. The records should be from the past few months and should describe your current symptoms and how they affect your ability to work.
