If you’ve already been rated at 90% disability by the Department of Veterans Affairs (VA), you are eligible for substantial benefits. However, reaching a 100% disability rating can unlock even greater benefits, including increased compensation, healthcare, and other VA services. The path to going from 90% to 100% VA disability involves understanding the rating system, gathering additional evidence, and potentially seeking an increase in your rating for one or more of your service-connected conditions.

Here’s how to work towards achieving a 100% disability rating with the VA:

Please answer a few questions to help us determine your eligibility.
Step 1: Understand How VA Disability Ratings Work
The VA uses a specific formula to determine your disability rating, assigning a percentage for each service-connected condition. These percentages are combined using a “whole person” approach rather than adding them up directly. For example, two 50% disabilities do not equal 100% but are instead combined to create a 75% disability rating, which would then be rounded up to 80%. You need a specific combination of conditions or an increase in severity to reach the 100% rating.
Step 2: Evaluate Your Current Service-Connected Conditions
To increase your rating from 90% to 100%, start by looking at the conditions that make up your current rating. You may already have one or more conditions rated at 50% or 70%, and to increase your overall rating to 100%, the most likely path is to either:
Step 3: Request an Increase for a Condition
If you believe that one of your current service-connected disabilities has worsened, you can apply for an increased rating. The process to do so involves submitting a Request for Increase to the VA. Here’s how to go about it:
Step 4: Seek Additional Service-Connected Disabilities
If you have other health conditions that were caused or aggravated by your military service but have not been rated by the VA, you may be able to seek service connection for those conditions. This could involve conditions like:
By seeking service connection for additional disabilities, you may receive higher overall disability ratings, helping you reach 100%.
Step 5: File for TDIU (Total Disability Based on Individual Unemployability)
If your service-connected disabilities prevent you from working, you might qualify for Total Disability based on Individual Unemployability (TDIU), which is a benefit for veterans who are unable to maintain gainful employment due to their service-connected disabilities. TDIU can grant you a 100% disability rating, even if your combined disability rating is less than 100%.
Step 6: Ensure All Evidence Is Submitted
When seeking an increase or additional service-connected conditions, ensure that you submit all relevant evidence to support your claim. This includes:
Step 7: Consider Hiring a Veterans’ Disability Attorney or Advocate
The VA claims process can be complex, and going from 90% to 100% disability is often challenging. A veterans’ disability attorney or accredited VA representative can help you navigate the system, gather the necessary evidence, and ensure that your claim is presented in the best possible light. An attorney can also assist with:
Step 8: Be Prepared for the VA’s Response
After submitting your request for an increase or new disability claim, the VA will review your case and may schedule a C&P exam (Compensation and Pension examination) to assess the severity of your conditions. Once the exam and review are complete, you’ll receive a decision.
