Traumatic Brain Injury and SSDI may be able to access

Traumatic brain injury (TBI) can support an SSDI claim, but the injury itself does not automatically mean you receive benefits. The Social Security Administration (SSA) must find that your TBI causes functional limitations severe enough to prevent substantial work for at least 12 months. The severity, location, and lasting effects of your injury determine whether you meet that threshold.

SSA does not have a single listing for TBI. Instead, the agency evaluates the specific impairments that result from your injury—cognitive decline, memory loss, balance problems, seizures, mood changes, or physical weakness. Your claim succeeds if one of these resulting conditions matches a medical listing, or if the combination of your symptoms is severe enough that you cannot work.

The timing of your injury matters. SSA looks at your current functional capacity, not your condition when ready after the accident. If you have recovered substantially in the months or years since the injury, that recovery reduces the likelihood of approval. If your deficits have persisted or worsened, that strengthens your case.

Key Takeaways

  • TBI does not have its own medical listing; SSA evaluates the specific impairments that result from your injury, such as cognitive loss, seizures, or balance problems.
  • You must show that your TBI-related symptoms prevent you from doing any substantial work for at least 12 months, not just that you cannot return to your previous job.
  • Medical evidence from your neurologist, neuropsychologist, or treating physician—including imaging, test results, and functional assessments—is the foundation of your claim.
  • SSA considers both how your injury affects your thinking and memory and how it affects your physical abilities, mood, and ability to follow instructions at work.

How SSA Evaluates TBI-Related Impairments

When you file a claim based on TBI, SSA looks for one of several medical listings that describe the lasting effects of brain injury. The most common routes are through listings for cognitive impairment, seizure disorder, motor dysfunction, or mood or anxiety disorders. Each listing has specific criteria—for example, a seizure listing requires documented seizures that occur despite prescribed medication, and cognitive listings require standardized test scores showing significant decline.

SSA will request your medical records from the hospital or emergency department where you were treated after the injury, your neurologist or neuropsychologist, and any other specialists who have evaluated you since. The agency looks for objective findings: CT or MRI scans showing structural damage, electroencephalogram (EEG) results if seizures are present, and neuropsychological testing that measures memory, attention, processing speed, and executive function.

If your test results and medical history do not match a specific listing exactly, SSA may still find you disabled through a process called medical-vocational allowance. This route requires showing that your combination of impairments—even if none alone meets a listing—is severe enough that you cannot work. For TBI, this often means demonstrating that cognitive or behavioral changes make it impossible to follow workplace instructions, maintain attention, or manage social interactions with coworkers and supervisors.

Medical Evidence That Strengthens a TBI Claim

SSA gives the most weight to evidence created close to the time of your injury and to ongoing treatment records. If you were hospitalized or treated in an emergency department after the TBI, obtain those records when ready. They establish the severity of the initial injury and create a baseline for comparison.

Neuropsychological testing is often the single most important piece of evidence in a TBI claim. This testing—which takes several hours and measures memory, attention, processing speed, language, and executive function—produces standardized scores that SSA can compare to the criteria in its medical listings. If you have not had this testing, your treating physician or a disability attorney can recommend a neuropsychologist. Testing typically costs $1,500 to $3,000 out of pocket, though some providers offer sliding scale fees.

Functional capacity evaluations (FCEs) and work capacity evaluations (WCEs) also carry weight. These assessments, usually performed by occupational or physical therapists, document what you can and cannot do in a work setting—how long you can sit, stand, or concentrate; whether you can follow multi-step instructions; and how you respond to errors or changes in routine. Bring these reports to your SSA interview or include them with your initial claim.

Treatment records showing ongoing symptoms matter as much as initial injury records. If you have been in speech therapy, occupational therapy, or cognitive rehabilitation since the injury, those records show that your deficits have not resolved. If you have been prescribed medications for seizures, mood changes, or attention problems, that documentation supports your claim.

The Difference Between Moderate and Severe TBI

SSA does not use the terms "mild," "moderate," or "severe" TBI in the same way that medical providers do. A moderate TBI by medical standards—one that caused loss of consciousness for 15 minutes to several hours—may or may not result in lasting impairments that prevent work. A mild TBI with persistent cognitive or mood changes may meet SSA's standard for disability if those changes are documented and severe.

What matters to SSA is whether your current functional capacity allows you to work. If you had a severe TBI five years ago but have recovered substantially and can now work part-time, you would not meet the standard. If you had a moderate TBI two years ago and still have significant memory loss, attention problems, or seizures that prevent full-time work, you may meet the standard.

SSA will also consider your age, education, and work history. A 55-year-old with a high school education and a history of manual labor faces a higher bar than a 35-year-old with the same TBI, because the older worker has fewer options for retraining. This is part of the medical-vocational allowance analysis and is why your age and background matter in your claim.

Common Reasons TBI Claims Are Denied

The most frequent reason SSA denies TBI claims is insufficient medical evidence. If you did not seek treatment when ready after the injury, or if you have not had ongoing treatment since, SSA may conclude that your symptoms are not as severe as you report. If you were treated in an emergency department but never followed up with a neurologist or specialist, SSA has limited objective evidence to review.

Another common reason is that your symptoms have improved. SSA recognizes that many people recover substantially from TBI, especially in the first year or two. If your medical records show improvement over time—better test scores, fewer seizures, return to part-time work—SSA may deny your claim even if you still have significant limitations.

Inconsistency between what you report and what your medical records show also leads to denial. If you tell SSA that you cannot concentrate for more than 15 minutes but your neuropsychological testing shows normal attention span, or if you report severe memory loss but your medical records do not document that finding, SSA will question your credibility. Be honest about your symptoms and make sure your doctors' notes reflect what you actually experience.

Work Incentives and TBI

If you are approved for SSDI based on TBI, you have access to work incentives that let you test your ability to work without when ready losing benefits. The most important is the Trial Work Period, which allows you to work and earn any amount for nine months without affecting your SSDI payment. After the Trial Work Period ends, you enter the Extended may be able to access Period, during which you can work and earn up to the substantial gainful activity (SGA) limit—$1,550 per month in 2024, though this amount changes yearly—without losing benefits.

You can also use Impairment Related Work Expenses (IRWE) to deduct the cost of items or services you need because of your TBI. If you require a job coach, assistive technology, or transportation to work because of cognitive or physical limitations from your injury, those costs may reduce your countable earnings and allow you to work at a higher income level while keeping your benefits.

These work incentives exist because SSA recognizes that people with disabilities, including TBI, often want to work and may be able to do so with support or accommodation. If you are considering returning to work, ask your SSA work incentives planning and information (WIPA) project for guidance. You can find your local WIPA at vcu-ntdc.org.

How to File a Claim Based on TBI

You can file for SSDI online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office. When you file, have ready the date of your injury, the names and contact information of all doctors who have treated you since the injury, and the dates of any hospitalizations or emergency department visits.

Gather your medical records before you file or when ready after. Request records from the hospital or emergency department, your neurologist or primary care doctor, any specialists you have seen, and any therapists or rehabilitation providers. If you have had neuropsychological testing, imaging (CT or MRI), or EEG results, include those. The more complete your medical file, the faster SSA can make a decision.

Consider working with a disability attorney or advocate. Many attorneys work on contingency, meaning they take a percentage of your back pay (up to 25 percent) only if you win. An attorney can help you gather medical evidence, prepare for your interview, and represent you if SSA denies your initial claim and you file an appeal. You can find attorneys through the National Organization of Social Security Claimants' Representatives (NOSSCR) at nosscr.org.

Frequently Asked Questions

Can I get SSDI for TBI if I was not hospitalized?

Yes, but you will need strong medical evidence of the injury and its lasting effects. If you were treated in an emergency department or by a doctor who documented the TBI, those records can support your claim. Neuropsychological testing showing cognitive decline is especially important when hospitalization records are not available.

How long does it take SSA to decide a TBI claim?

Initial decisions typically take three to six months, though this varies by your local SSA office and the complexity of your medical records. If SSA denies your claim, you can appeal, and the appeals process can take another year or longer. Working with an attorney can sometimes speed up the process.

What if I had TBI years ago and am just now explore for SSDI?

SSA can approve you based on a past injury, but you will need current medical evidence showing that your symptoms persist and prevent work. If you have not been treated since the injury, seek an evaluation from a neurologist or neuropsychologist before you file. SSA will also look at whether you have been working since the injury; if you have worked substantially, that suggests your TBI did not prevent work.

Does TBI automatically may have access to me for Medicare?

No. If you are approved for SSDI, you become may be able to access for Medicare after you have been receiving SSDI for 24 months. TBI itself does not trigger Medicare; SSDI approval does. During the first 24 months of SSDI, you may be covered by Medicaid instead, depending on your state.

Can I work part-time while waiting for an SSDI decision?

Yes. Working part-time does not disqualify you from SSDI, and SSA will consider your current work capacity as part of your claim. However, if you are earning above the SGA limit ($1,550 per month in 2024), SSA may conclude that you can do substantial work and deny your claim. Keep your earnings below that threshold if possible while your claim is pending.
