Social Security Disability for Traumatic Brain Injury (TBI)

A traumatic brain injury (TBI) is a type of brain dysfunction caused by a violent blow or head injury. TBIs are classified into two categories: penetrating and non-penetrating. Penetrating TBIs happen when an object goes through brain tissue, such as a bullet or bone fragment. Non-penetrating (“blunt force”) TBIs are the result of an external force strong enough to move the brain around inside the skull, like a car accident, fall, or sports injury.

Because a TBI can result in long-term cognitive and physical defects that keep you from working full-time, it can form the basis of a successful Social Security disability claim. (Veterans who have a service-connected TBI may qualify for a VA disability rating as well.) Before you file for benefits, it’s important to understand what medical records and functional limitations the agencies will be looking for so that you can increase your chances of getting approved.

Does TBI Automatically Qualify for Disability?

Not necessarily—it depends on how severely the TBI restricts your activities of daily living. Social Security awards benefits to people who have a medical impairment that keeps them from earning at or above substantial gainful activity for at least twelve months. So if your TBI symptoms improve within one year or you never stop working below the substantial gainful activity level ($1,690 per month in 2026), you won’t be eligible for SSDI or SSI benefits.

However, TBI is in Social Security’s “Blue Book” list of disorders that the agency considers especially severe. If you can meet the requirements of a “listing,” then you can get disability automatically (assuming that you meet the non-medical requirements of either the SSDI or SSI programs). You can be found disabled under listing 11.18, Traumatic brain injury, with medical evidence of the following limitations:

• you’re having so much trouble using at least two of your extremities—your arms, legs, or both—that you’re unable to perform basic movements like standing up from a seated position without help, or
• you can move independently (but with great difficulty) and you’re also having significant challenges with mental activities such as interacting with others, finishing tasks, or adapting to changes.

The above limitations must exist for at least three months in a row after your injury occurred to meet listing 11.18. If you had a TBI but don't have lasting physical problems, your condition would be evaluated under listing 12.02 for neurocognitive disorders. For more information, see our article on getting disability for a neurocognitive disorder.

What If I Don’t Qualify Automatically With a TBI?

Cognitive and physical changes resulting from a TBI can manifest immediately after the traumatic event, while others take longer to develop. (Repeated head injuries may cause a type of brain degeneration called chronic traumatic encephalopathy, or CTE). So even if you have TBI symptoms that don’t meet the requirements of 11.18—perhaps because they started more than three months after the injury—you can still get disability benefits if you can show that changes in your mental and physical abilities keep you from working at any full-time job.

In order to determine whether you’re able to work, Social Security looks at your medical records and self-reported activities of daily living to determine what you can and can’t do in a work environment, a process the agency calls assessing your residual functional capacity (RFC). Depending on your TBI symptoms, your RFC will likely contain descriptions of physical and mental activities that you should avoid doing at work.

For example, if you have trouble with muscle weakness, your RFC might state that you should avoid lifting more than 10 pounds or walking more than 2 hours total out of an 8-hour day. Any difficulties you have with focus and concentration could be reflected in being limited to unskilled jobs. The more severe your symptoms are, the more limitations you’ll have in your RFC. Multiple moderate limitations in several functional areas might make you unable to work—even though you don’t have marked or extreme limitations in any one area—particularly if you have other physical conditions in addition to your TBI.

Social Security uses your RFC to determine whether you’re capable of returning to any jobs you’ve done in the past. If you can’t do your past work and you’re over 50, you might qualify for disability under a special set of rules known as the medical-vocational grid. For people under the age of 50, the SSA will need to see that you can’t do even the easiest, least stressful jobs.

Evidence You’ll Need to Get Disability for TBI

Whether by meeting a listing or having an RFC that rules out all work, you won’t get disability benefits without supportive medical evidence. Ideally, that means you’ll have documentation of ongoing treatment for symptoms (mental, physical, or both) of TBI as well as objective imaging that your doctors used to make a diagnosis.

Symptoms of Traumatic Brain Injury

Because TBIs result in damage to the brain, they can have an effect on a wide variety of body systems. The most common symptoms fall into three categories: physical, mental, and sensory.

Physical symptoms of TBI include:

• persistent headache or migraine
• vomiting or nausea
• convulsions or seizures
• dizziness or loss of balance, and
• muscle weakness, numbness, or loss of coordination.

Mental (psychological or cognitive) symptoms of TBI include:

• mood changes or mood swings
• difficulty with memory or concentration
• confusion, and
• agitated, combative, or other unusual behavior.

Sensory symptoms of TBI include:

• sensitivity to light or sound
• blurred vision, ringing in the ears, or a bad taste in the mouth
• changes in the ability to smell, and
• slurred speech.

Very severe traumatic brain injuries can cause a temporary or permanent change in consciousness, such as a coma, vegetative state, or brain death. (People who’ve been in a coma for 30 days or longer can receive a quick approval of disability benefits under Social Security’s terminal illness program.)

Diagnosis and Treatment for TBI

Doctors determine how severe the damage to the brain is by reviewing imaging like a CT scan or an MRI. Your disability application should contain documentation of such medical imaging so that the SSA knows that you’ve been diagnosed with a traumatic brain injury.

Treatment for TBI will vary depending on the results of the imaging. Mild cases might resolve after a few days or weeks of rest, but moderate to severe TBI can require more invasive procedures or intensive therapy.

• Medications such as diuretics may be prescribed that reduce pressure on the brain due to fluid buildup. Anticonvulsants can help lower the elevated risk of seizures after TBI.
• Surgery might be needed to minimize damage to brain tissue. This includes repairing skull fractures, stopping bleeding in the brain, and removing clotted blood (hematomas).
• Rehabilitation is common for people with TBI to relearn basic skills. Physical therapists may be needed for mobility struggles, while neuropsychologists can improve brain function.

When you submit your application for disability benefits, make sure that you provide Social Security with the names, dates, and locations of all the medical providers you’ve seen for your TBI. The agency will want to see admission and discharge dates of any hospital stays, as well as progress notes from your doctors, neurologists, and rehabilitation specialists.

You can help support your disability claim by including a medical source statement with your application. Social Security values the opinions of medical professionals who've been treating you for a while and have special insight into what difficulties you're having, physically and mentally, following your TBI. Consider bringing a blank mental RFC assessment form with you to your next appointment and asking your doctor to complete it.

VA Disability for TBI

Veterans who have a TBI that’s related to their time on active duty may be assigned a disability rating according to the VA Schedule for Rating Disabilities under diagnostic codes 8045 (for traumatic brain injury residuals) or 9304 (for major or mild neurocognitive disorder due to traumatic brain injury).

Because each TBI manifests different symptoms, these diagnostic codes don’t have a specific disability rating scale. Instead, you’ll be evaluated according to the rating schedule for the affected body part or the VA level of impairment table for “cognitive impairment and other residuals of TBI not otherwise classified”. (38 C.F.R. 4 (2026)). This table provides for levels of impairment that correspond to 0%, 10%, 40%, and 70% disability ratings, depending on the degree of limitations.

Social Security and VA Disability Benefit Amounts

Social Security doesn’t make payments based on the kind of disability you have. Instead, how much you’ll receive depends on which type of benefit program you’re eligible for—Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI). SSDI eligibility is based on how many work credits you have, while SSI is reserved for people with limited income and assets. You can learn more (and calculate your estimated benefit) in our article on SSDI and SSI monthly check amounts.

VA disability compensation is calculated differently, using a combination of your disability rating and your living situation. The higher your VA rating, the more you’ll receive in monthly compensation, and the VA will increase your benefits if you have a dependent spouse, children, or parents. You can visit the VA website listing the current disability compensation rates to see the tables used to determine monthly benefit amounts.

How to Apply for Disability

You can file for Social Security disability benefits using the following methods:

• File online at theSocial Security website.
• Call the SSA at 800-722-1212 from 7 a.m. to 7 p.m. Monday through Friday. If you’re deaf or hard of hearing, you can call the TTY number at 800-325-0778.
• Visit your nearest Social Security field office and apply in person.

For additional details, check out our step-by-step guide on applying for SSDI or SSI.

Applying for VA benefits is done in a similar manner. You'll need to complete Form 21-526EZ, Application for Disability Compensation and Related Compensation Benefits, which you can do in a few ways:

• File online using the electronic version of Form 21-526.
• Fax Form 21-526EZ to 844-531-7818 (from inside the United States) or 248-524-4260 (from outside the U.S.).
• Bring your application to your local VA office.
• Mail the form to the Department of Veterans Affairs, Claims Intake Center, PO Box 4444, Janesville, WI 53547-4444.

What If My Application Was Denied?

Not many people are awarded disability benefits on their first try. But if you’ve received a Social Security denial or disagree with your VA rating, you can (and probably should) appeal the decision, preferably with help from an experienced disability attorney or advocate.

You aren’t required to have an attorney to appeal a denial, but it’s usually a good idea. An experienced disability lawyer or advocate can help you gather the proper medical paperwork, make sure you don’t miss important deadlines, and represent you at a disability hearing. And because disability lawyers aren’t allowed to charge you if you don't win—and they’re limited to a small percentage of your disability backpay if you do win—there’s little risk in finding a lawyer near you to help with your claim.
