The core things Social Security checks

When Social Security reviews your case for SSDI, they look at five main things: whether you have enough work credits for your age, whether you've been unable to work for at least 12 months or have a condition expected to result in death, the medical evidence supporting your condition, your current income and resources, and whether you're still working or earning above the monthly limit.

This is not a checklist where checking every box automatically leads to approval. Social Security weighs the medical evidence most heavily. A doctor's statement alone is not enough—they want to see test results, imaging, treatment records, and how your condition actually affects your ability to work in any job, not just your old job.

The work credits requirement depends on your age. If you're under 24, you need only 6 credits earned in the 3 years before you became disabled. If you're 24 to 31, you need credits for half the time between age 21 and when you became disabled. At 31 and older, you need 20 credits earned in the 10 years before disability, though the exact number varies slightly by age.

Key Takeaways

  • Social Security requires medical evidence—test results, imaging, and treatment records—not just a doctor's statement that you cannot work.
  • You must show you cannot do any job available in the national economy, not just that you cannot return to your previous work.
  • The number of work credits you need depends on your age at the time you became disabled, ranging from 6 credits for those under 24 to 20 credits for those 31 and older.
  • If you are working or earning over the monthly limit (currently $1,550 for non-blind individuals, though this amount changes yearly), Social Security will likely deny your claim or stop your benefits.
  • Your case is reviewed by a disability examiner and a medical or psychological consultant, not by a single person.

How Social Security measures your medical condition

Social Security does not accept your word that you cannot work. They build what they call a "residual functional capacity" assessment—a detailed picture of what physical and mental tasks you can still do, even with your condition. This comes from your medical records, not from a form you fill out.

They look for consistency. If your doctor says you cannot lift more than 10 pounds, but your medical records show you were gardening or doing home repairs, Social Security will note the contradiction. They also check whether you've actually been treating your condition. If you have not seen a doctor in six months and then suddenly file for SSDI, they will question how severe the condition really is.

The medical evidence must show objective findings—things a doctor can measure or observe—not just your reported pain or fatigue. An MRI showing a herniated disc is objective. Saying your back hurts is not. This does not mean pain conditions cannot may have access to, but Social Security needs imaging, nerve tests, or other measurable signs to support the diagnosis.

Why work credits matter even if you're very sick

Work credits are a separate requirement from medical severity. You can have a condition that would clearly prevent you from working, but if you do not have enough work credits for your age, Social Security will deny your claim. This is why someone who became disabled at age 22 after working for only one year cannot receive SSDI, even with severe medical evidence.

Each work credit requires you to have earned a certain amount of income in that year—$1,550 in 2024, though this amount increases yearly. You can earn up to four credits per year. The credits stay on your record indefinitely, so work you did ten years ago still counts. But there is a time limit: credits earned more than roughly 13 years ago do not count toward the requirement for most people under 31.

What Social Security does with your income and resources

Social Security checks whether you are currently working or earning money. If you are working and earning over $1,550 per month (the 2024 limit for non-blind individuals), they will assume you can work and likely deny your claim. This limit is called "substantial gainful activity," and it changes every year.

They also look at your total resources—savings, property, vehicles—but only for Supplemental Security Income (SSI), not for SSDI. SSDI has no resource limit. However, if you own a business or are self-employed, Social Security will examine your business records to determine whether you are actually working or whether the business is inactive.

How the review process actually works

Your case is assigned to a disability examiner, who is a Social Security employee, not a doctor. The examiner gathers your medical records, contacts your doctors if needed, and builds a file. They then send the file to a medical or psychological consultant—a doctor or psychologist hired by Social Security—who reviews the medical evidence and writes an opinion about your functional capacity.

The examiner and consultant work together to decide whether your condition meets or equals one of Social Security's listed impairments, or whether your condition is severe enough that you cannot do any work in the national economy. This is a two-person review, not an automated system. The examiner can disagree with the consultant's opinion, and either can request more medical evidence before making a decision.

If Social Security denies your claim, you have the right to appeal. Most people who are denied at the initial level are also denied at reconsideration, but many win at the hearing stage, where you can present your case to an administrative law judge and provide new medical evidence.

The difference between meeting a listing and proving you cannot work

Social Security maintains a list of conditions that, if your medical evidence matches them exactly, automatically may have access to you for SSDI. These are called "listings" or "the Blue Book." Meeting a listing is the fastest path to approval because Social Security does not have to assess your functional capacity—the condition itself is considered disabling.

If your condition does not meet a listing, Social Security must still consider whether you cannot do any work available in the national economy, given your age, education, and work history. This is called a "residual functional capacity assessment." It is more subjective than meeting a listing, which is why many people who do not meet a listing are still approved—but it also means approval takes longer and requires stronger medical evidence.

What Social Security ignores about your situation

Social Security does not care whether you cannot find an employer willing to hire you. They care whether work exists in the national economy that you could physically and mentally do. If you have severe arthritis in your hands but can still sit and do data entry, Social Security will say that work is available to you, even if no employer in your town is hiring.

They also do not consider your age, education, or work history until after they determine whether your medical condition alone prevents all work. Only if your condition does not automatically disqualify you do they factor in whether someone your age with your background could transition to different work.

Social Security does not consider whether you have family support, whether you own your home, or whether you have other income. These factors do not affect SSDI approval. They do affect SSI, which is the needs-based program for people with low income and resources.

Frequently Asked Questions

Does Social Security contact my doctor directly, or do I have to get the records myself?

Social Security can contact your doctor directly if you sign a release form. However, you should also gather your own medical records and submit them with your claim, because doctors' offices are sometimes slow to respond. The faster your records reach Social Security, the faster your case moves.

What if I have been disabled for only six months—can I still file?

You can file at any time, but Social Security will not approve you until you have been unable to work for 12 months or have a condition expected to result in death. If you file early, they will hold your claim and make a decision once the 12-month period is met, assuming your condition has not improved.

Can I be approved for SSDI if I do not have enough work credits?

No. Work credits are a separate requirement from medical severity. If you do not have enough credits for your age, Social Security will deny your claim regardless of how severe your condition is. However, you may be able to file for SSI instead, which does not require work credits but does have income and resource limits.

What happens if I disagree with the medical consultant's opinion about my functional capacity?

You can submit additional medical evidence from your own doctors and request reconsideration or appeal. At the hearing stage, you can present your doctors' opinions directly to an administrative law judge. The judge is not required to follow the Social Security consultant's opinion if your medical evidence contradicts it.

Does Social Security look at my mental health records the same way they look at physical conditions?

Yes. Mental health conditions must be supported by treatment records, test results, and a doctor's assessment of how the condition affects your ability to work. Social Security looks for consistency between your reported symptoms and your actual functioning, just as they do with physical conditions.
