Achieving a 100% VA disability rating can open the door to life-changing benefits, including tax-free monthly compensation, full VA healthcare, dependents’ benefits, and more.
While there are conditions that can qualify for a 100% VA rating on their own, most veterans who earn a 100% rating do so by combining multiple service-connected disabilities.
A 100% VA disability rating is possible for many veterans, but only if the severity of your condition, or combination of conditions, meets the VA’s criteria for total disability. Not every veteran will qualify, but with the right evidence and approach, it could be within reach.
This guide breaks down the top 5 claims most commonly rated at 100% and explains how a combined VA rating may help you get there, even if no single one of your conditions is rated that high.

Summary of Key Points
- Most veterans who reach 100% do it through combined ratings. The VA uses “VA math,” which applies each condition to the remaining efficiency of your body.
- Some conditions qualify for a 100% VA rating automatically. ALS and active cancers are rated 100% upon current diagnosis or during treatment.
- TDIU pays at the 100% rate without a 100% VA rating. If your service-connected conditions prevent you from maintaining substantially gainful employment, TDIU may provide full compensation, even with a lower combined rating.
Top 5 VA Claims That May Qualify for 100% Disability
1. Traumatic Brain Injury (TBI)
TBI is a common service-connected condition among veterans, often caused by blasts, falls, or blunt force trauma during military service.
The VA rates TBI under diagnostic code 8045 based on residual symptoms you have due to your injury and uses a scale of 0,1, 2, 3, or total when rating TBI residual symptoms.
Veterans with moderate to severe TBI may qualify for a 100% VA rating if they experience:
- Significant cognitive impairment
- Inability to manage daily activities independently
- Poor judgment, disorientation, or severe memory loss
- Loss of motor function or speech
TBI can also lead to secondary conditions like depression, migraines, or sleep disorders, each of which can be rated separately and may increase your overall combined disability rating.

2. Post-Traumatic Stress Disorder (PTSD)
PTSD is a commonly rated service-connected condition among veterans. It’s a mental health disorder triggered by experiencing or witnessing traumatic events, such as combat, military sexual trauma, or life-threatening situations.
The VA rates PTSD under DC 9411, assigning ratings from 0% to 100% based on the severity of symptoms and how much they disrupt your daily life, especially your ability to work and maintain relationships.
Many veterans receive high ratings for PTSD due to symptoms like hypervigilance, nightmares, isolation, depression, memory issues, and panic attacks, all of which can severely affect social and occupational functioning.
If your PTSD causes total occupational and social impairment, including persistent delusions, severe emotional disturbance, or risk of harm to self or others, you may qualify for a 100% VA disability rating.

3. Amyotrophic Lateral Sclerosis (ALS)
ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, leading to muscle weakness, loss of mobility, difficulty speaking or breathing, and eventual paralysis.
The VA recognizes ALS as a presumptive service-connected condition for all veterans with at least 90 days of continuous active service. That means you don’t need to prove a specific in-service event caused your ALS; just a confirmed current diagnosis.
Under DC 8017, ALS is automatically rated at 100% due to its progressive and debilitating nature. You don’t have to show current symptoms beyond the diagnosis to qualify.
Because ALS is automatically rated at 100%, you don’t need to combine it with other disabilities to reach full compensation.
In addition, veterans with ALS may also qualify for Special Monthly Compensation (SMC) based on their level of impairment and need for aid and attendance.

4. Certain Cancers (Active or Under Treatment)
If you’re diagnosed with active cancer or currently undergoing treatment, such as chemotherapy, radiation, or surgery, you’re eligible for an automatic 100% VA disability rating.
This applies to a wide range of service-connected cancers, including prostate cancer, lung cancer, leukemia, and others, especially those linked to toxic exposures like Agent Orange or burn pits.
The 100% rating continues throughout the treatment period and for at least six months after treatment ends. After that, the VA will schedule a follow-up Compensation & Pension (C&P) exam to determine any lasting residual effects.
If the cancer is in remission but causes ongoing health issues, such as fatigue, organ damage, or chronic pain, those residuals may still qualify for a separate disability rating.

5. Loss of Use of Both Hands, Feet, or Both
The VA assigns a 100% disability rating for the loss of use of both hands, both feet, or one hand and one foot, meaning the limbs can no longer perform basic tasks like walking, grasping, or lifting.
This doesn’t require amputation. “Loss of use” applies when the remaining function is so limited that a prosthetic would serve the veteran just as well.
The VA evaluates these conditions under Diagnostic Codes 5104–5111 in the musculoskeletal ratings schedule.
Veterans with loss of use may also qualify for Special Monthly Compensation due to the severity of the impairment.
Note: Loss of use doesn’t always equal a 100% VA rating. If the loss is partial, such as limited function in a hand or foot, you may receive a lower rating depending on the severity and impact on daily activities.
How Most Veterans Who Reach 100% Actually Get There
The VA doesn’t add disability percentages like simple math. Instead, it uses “VA math,” which ranks conditions by severity and applies each additional rating to the portion of the body that remains “unaffected.”
Example:
50% PTSD rating + 30% rating for migraines + 20% rating for back pain ≠ 100% VA rating
This combination equals 72% (which rounds down to a 70% VA rating).
That’s why moving from 90% to 100% is known as “the hardest 10%.” You often need another high-value condition, typically rated 50% or more, to close the gap.
The good news? It’s possible with the proper qualifications.
According to the 2024 VA Annual Benefits Report, 70,035 veterans received a new 100% combined VA disability rating, a 20% increase from the year before.
Examples of combined ratings that may reach 100%:
- PTSD + Sleep Apnea + Migraines
- Back Pain + Bilateral Radiculopathy + Mental Health
- Hearing Loss + Tinnitus + Joint Damage + Depression

4 Tips for Reaching 100% VA Disability
- File for VA secondary conditions. Many 100% VA ratings include secondary claims like sleep apnea, GERD, radiculopathy, or mental health conditions tied to chronic pain.
- Don’t overlook “mild” issues. Conditions like migraine headaches, IBS, or scars can contribute to your combined rating.
- File a new VA disability claim. If your symptoms worsen, you can file a new VA increase claim to potentially receive a higher VA rating.
- Use DBQs and nexus letters. These are key tools to support your claim, especially for VA secondary conditions. DBQs can also document worsening severity of symptoms.
Pro Tip: There are no guarantees, but your best chance is to submit a complete, well-supported claim with strong medical evidence and clear links to your service.

Is TDIU For You?
Total Disability Based on Individual Unemployability (TDIU) is a way for eligible veterans to receive the 100% disability rate even if their combined VA rating is less than 100%.
This applies when service-connected conditions make it impossible to secure and maintain substantially gainful employment.
To qualify, a veteran must have either one disability rated at 60% or more, or two or more disabilities with a combined rating of 70% or more, with at least one of those disabilities rated at 40% or more.
TDIU gives full monthly compensation, but there’s a strict income limit. If you want to work, carefully track your hours and pay to ensure you don’t exceed the VA’s limits. For example, your earnings can’t exceed the poverty threshold.
