The Five Core Things SSA Examines

When the Social Security Administration reviews your SSDI claim, it looks at five specific things in this order: your work history and credits, your medical condition and its severity, whether your condition meets or equals a listed impairment, your ability to do your past work, and your ability to do any other work that exists in the economy. The first decision point is almost always work credits—if you do not have enough, SSA stops the review there. If you do, the medical evidence becomes the focus.

SSA does not make a judgment call about whether your condition "seems serious enough." Instead, it compares your medical records against a specific list of conditions and their required findings. This list, called the Blue Book, contains over 100 impairments organized by body system. Your records must show findings that match or exceed what the Blue Book says is disabling for that condition.

Key Takeaways

  • SSA first checks whether you have earned enough work credits in the years before you became unable to work—this is a hard threshold, not a judgment.
  • Your medical records must show objective findings (test results, imaging, clinical notes from doctors who examined you) that match or exceed the Blue Book criteria for your condition.
  • SSA examines whether you can still do the specific job you held before, using the actual job description and your documented abilities.
  • If you cannot do your past work, SSA looks at whether any other work exists in the national economy that you could do given your age, education, and work history.
  • The entire review is based on written medical records and your work history—SSA does not make assumptions about what you might be able to do.

Work Credits: The First Gate

Before SSA examines anything else, it counts your work credits. You earn one credit for each quarter (three-month period) in which you earned at least a minimum amount of wages and paid Social Security taxes. In 2024, that minimum is $1,730 per quarter, though the amount changes yearly. You need 40 credits total to be insured for SSDI, and at least 20 of those credits must have been earned in the 10 years before you became unable to work.

SSA pulls this information directly from your Social Security earnings record. You can view your own record by creating an account at ssa.gov. If you do not have 40 credits, or if fewer than 20 were earned in the past 10 years, your claim will be denied before any medical review happens. This is not discretionary—it is a mathematical fact based on your W-2s and tax records.

Medical Evidence: What SSA Actually Needs

Once SSA confirms you have enough work credits, it shifts to your medical records. SSA does not accept your word that you are disabled. It requires objective medical evidence—meaning test results, imaging studies, clinical examination findings, and detailed notes from treating physicians. A letter from your doctor saying "this patient cannot work" is not enough by itself. SSA needs the underlying findings that support that conclusion.

For conditions like diabetes, SSA looks for blood glucose readings, HbA1c test results, and documentation of complications. For back pain, it looks for imaging (MRI or CT scans), findings from a physical examination, and notes about range of motion and strength. For mental health conditions, it looks for clinical notes describing your symptoms, results from standardized testing, and documentation of how those symptoms affect your functioning in daily life. The records must be recent—usually from within the past three months—and they must be from a medical source, not from a non-medical person.

SSA also looks at whether you have followed prescribed treatment. If your doctor recommended medication or therapy and you did not pursue it without a documented reason, SSA may find that your condition is not as severe as you claim. This is called "failure to follow treatment" and can result in a denial even if your condition would otherwise be disabling.

The Blue Book: The Standard SSA Uses

The Blue Book is SSA's official list of impairments that are considered disabling. It is organized by body system—musculoskeletal, respiratory, cardiovascular, neurological, mental disorders, and so on. For each impairment, the Blue Book lists the specific medical findings required to meet that impairment.

For example, the Blue Book section on Chronic Obstructive Pulmonary Disease (COPD) requires either a forced expiratory volume (FEV1) test result below a certain threshold, or evidence of cor pulmonale (heart strain from lung disease), or repeated hospitalizations. Your medical records must show at least one of these findings. If your records show you have COPD but do not document any of these specific findings, SSA will not find that you meet the listing, even though you have the diagnosis.

SSA also has a process called "medical-vocational allowance" for people whose conditions do not quite meet a Blue Book listing but are still severe enough to prevent work. This requires SSA to look at your age, education, work history, and residual functional capacity (what you can still do physically and mentally) and determine whether any work exists for someone in your situation. This is a more subjective step, but it still relies entirely on the medical evidence in your file.

Residual Functional Capacity: What You Can Still Do

SSA uses a form called the Residual Functional Capacity (RFC) assessment to document what you can still do despite your impairments. The RFC describes your physical abilities (how much you can lift, how long you can stand or sit), your mental abilities (your ability to understand instructions, concentrate, interact with others), and any other limitations. SSA bases the RFC on your medical records, not on your own statements about what you cannot do.

If your medical records show you have severe arthritis in both hands, the RFC might say you can perform only sedentary work with no fine manipulation. If your records show you have anxiety disorder with panic attacks, the RFC might say you cannot work in jobs requiring public interaction or high-stress decision-making. The RFC is the bridge between your medical condition and whether you can work.

Your Past Work: Can You Still Do It?

SSA looks at the specific job you held before you became unable to work. SSA does not just ask "were you a teacher?" It looks up the actual job description for a teacher—the physical demands, the cognitive demands, the pace, the environment. Then it compares that job description to your RFC. If your RFC says you cannot stand for more than two hours at a time, and your past job required standing six hours a day, you cannot do your past work.

SSA uses the Dictionary of Occupational Titles (DOT) and its own occupational information to define what each job requires. This is important because it means SSA is not judging based on what your particular employer required, but on what the job typically requires in the national economy. You might have had a desk job as a teacher, but SSA will still consider the standard teaching job, which involves standing and moving around a classroom.

Other Work in the National Economy

If SSA determines you cannot do your past work, it then looks at whether any other work exists in the national economy that you could do given your age, education, work history, and RFC. This is where age becomes a factor. If you are 55 or older, SSA applies different standards than it does for someone who is 35. Older workers are given more consideration because retraining for a new field is harder.

SSA uses vocational experts and labor statistics to determine what jobs exist and whether someone with your profile could transition to them. For example, if you were a construction worker with a high school education and your RFC says you can do sedentary work, SSA might look at whether you could do a data entry job or a customer service job. If SSA finds that work exists that you could do, your claim will be denied, even if that work pays less than your past job or is harder to find.

Frequently Asked Questions

Does SSA look at how much pain I am in?

SSA looks at what your medical records say about your pain and what it prevents you from doing, not at your own statements about pain level. If your doctor's notes document severe pain and its effects on your functioning, that is evidence. If you tell SSA you are in severe pain but your medical records show normal examination findings and no treatment, SSA will not find you disabled based on pain alone.

What if I have multiple conditions that together make work impossible?

SSA considers the combined effect of all your impairments, not each one in isolation. If you have diabetes, arthritis, and depression, SSA will look at how all three together affect your RFC. However, each condition still needs to be supported by medical evidence. You cannot combine mild versions of multiple conditions to reach a disabling level without medical documentation of each.

Can SSA deny my claim if I did not follow my doctor's treatment plan?

Yes. If your doctor prescribed medication or therapy and you did not pursue it without a documented medical reason, SSA may find that your condition is not as severe as claimed. The exception is if the treatment itself is contraindicated (harmful to you) or if you have a documented reason such as severe side effects that your doctor acknowledged.

Does SSA consider my age when deciding if I am disabled?

Age matters only after SSA determines you cannot do your past work. If you are 55 or older, SSA applies a more lenient standard when deciding whether you could transition to other work. If you are under 50, SSA assumes retraining is more feasible. Age does not affect whether your condition meets a Blue Book listing.

What happens if my medical records are incomplete?

SSA will request records from your doctors and may order a consultative examination at SSA's expense. However, if records remain incomplete and do not show the findings required by the Blue Book, SSA will likely deny your claim. You have the right to submit additional records before your claim is decided, and you can appeal if you gather more evidence after a denial.
