What Determines Whether You may have access to

Social Security Disability Insurance (SSDI) has three hard requirements, and you must meet all three. First, you must have a medical condition that prevents you from working and is expected to last at least 12 months or result in death. Second, you must have worked long enough and recently enough to have earned enough work credits — a measure of your employment history, not your age. Third, your condition must be severe enough that you cannot do any work that exists in the national economy, not just your old job.

The Social Security Administration (SSA) does not decide based on how much pain you are in, how much your condition affects your daily life, or how much you want to stop working. They decide based on whether your medical records show a condition that meets their rules and whether you have the work history to may have access to. This is why many people are denied the first time they explore — not because their condition is not real, but because their medical evidence does not match SSA's criteria or their work history falls short.

Key Takeaways

  • You must have a medical condition expected to last 12 months or longer, a sufficient work history measured in work credits, and medical evidence showing you cannot work at any job in the national economy.
  • Work credits are earned by working and paying Social Security taxes; most people need 40 credits total, with 20 earned in the 10 years before they became disabled.
  • SSA uses a five-step process to evaluate your case, and most denials happen because medical evidence is incomplete or does not match SSA's specific criteria, not because your condition is not real.
  • You can request a reconsideration or appeal a denial, and many people are approved on appeal after submitting additional medical records or testimony.

Work Credits and Your Employment History

A work credit is earned when you work and pay Social Security taxes. In 2024, you earn one credit for each $1,705 in wages (this amount changes yearly). You can earn a maximum of four credits per year. Most people need 40 credits total to may have access to for SSDI, but you also need to have earned 20 of those credits in the 10 years before you became disabled.

This means if you stopped working five years ago and have not worked since, you may not have enough recent credits even if you worked steadily earlier in your life. If you are under 31, SSA uses a different rule — you generally need credits equal to your age minus 16, with half earned in the three years before you became disabled. The SSA will tell you exactly how many credits you have when you contact them or when you submit your process.

How SSA Evaluates Your Medical Condition

The SSA uses a five-step process to decide whether your condition qualifies. Step one checks whether you are working and earning more than a certain amount (in 2024, $1,550 per month). If you are, you are usually denied. Step two checks whether your condition is severe — meaning it causes more than minor limitations on your ability to work. If it is not, you are denied.

Step three is the hardest: SSA checks whether your condition matches one of the conditions on their Blue Book, a list of conditions they consider automatically disabling if your medical evidence meets their specific criteria. If your condition is on the list and your records match, you are approved. If it is not on the list or your records do not match closely enough, SSA moves to step four.

Step four asks whether you can do the work you did in the past 15 years. If you can, you are denied. Step five asks whether you can do any other work that exists in the national economy, given your age, education, and work history. If you can, you are denied. If you cannot, you are approved.

Medical Evidence SSA Actually Needs

SSA does not make decisions based on your own description of your symptoms. They need medical records from a doctor, psychiatrist, or other licensed medical professional who has examined you. These records must include test results, imaging, lab work, or clinical observations — not just your report of pain or fatigue.

The records must also show how your condition affects your ability to sit, stand, walk, lift, carry, concentrate, remember instructions, or interact with others. A letter from your doctor saying "this patient is disabled" is not enough. SSA needs records showing what you cannot do and why, based on objective findings or detailed clinical observations over time. If your medical records are thin or old, SSA will often deny you and ask you to get more recent treatment and records before you reapply.

Why People Are Denied and What Happens Next

The most common reason for denial is incomplete medical evidence. You may have a real, severe condition, but if your doctor has not documented it thoroughly or you have not been treated recently, SSA cannot approve you. The second most common reason is that your work history does not meet the credit requirement. The third is that your medical records do not match SSA's specific criteria for your condition.

If you are denied, you receive a written decision explaining why. You then have 60 days to request a reconsideration, which means SSA reviews your case again, usually with a different examiner. If you are denied again, you can request a hearing before an Administrative Law Judge, where you can present new evidence and testify. Many people are approved at the hearing stage after submitting additional medical records or having a doctor testify on their behalf.

What to Do Before You Contact SSA

Before you explore, gather your medical records from the past three to five years. Contact every doctor, hospital, mental health provider, or clinic that has treated you and ask for copies of your records. Include any test results, imaging reports, lab work, or clinical notes. If you have not been treated recently, schedule an appointment with your doctor and explain that you are considering explore for disability — this gives your doctor a chance to document your current condition thoroughly.

Write down the dates you worked at each job and the type of work you did. You will need this information when you explore. If you have not worked in several years, write down when you stopped and why. If you are still working, write down how many hours per week and how much you earn per month. The SSA will ask all of this, and having it ready speeds up the process.

Frequently Asked Questions

Do I have to be unable to work at all to may have access to?

Yes. SSA requires that you cannot do any work that exists in the national economy, not just your old job. If you can do any other type of work — even part-time or lower-paying work — you will likely be denied. However, you can earn up to $1,550 per month (in 2024) and still be considered disabled; this amount is called the Substantial Gainful Activity limit and changes yearly.

What if my condition is not on the Blue Book?

You can still be approved. If your condition is not on the list, SSA moves to step four and five of their evaluation — they ask whether you can do your past work or any other work. You can be approved if your medical evidence shows you cannot work, even if your specific condition is not listed. However, approval is harder without a Blue Book match, so your medical records must be very thorough.

Can I work part-time while receiving SSDI?

You can earn up to $1,550 per month (in 2024) without losing your benefits, but this is a limit, not a may provide. If you earn more than this amount, SSA will review your case to see whether you are still disabled. Additionally, you must report all work to SSA; failing to report work can result in overpayment and the need to repay benefits.

How long does it take to get a decision?

Initial decisions usually take three to five months, though this varies by state and how complete your process is. If you are denied and request a hearing, the wait is typically one to two years depending on your local hearing office's backlog. During this time, you can continue to work and earn, and if you are eventually approved, you may receive back pay to the date you became disabled.

What if I disagree with SSA's decision about my work credits?

You can request a detailed statement of your earnings record from SSA. If you believe there is an error — such as wages that were not credited to your account — you can file a request to correct your record. You have a time limit to do this, so contact SSA as soon as you notice a discrepancy. Bring pay stubs, W-2 forms, or tax returns as proof.
