    CCK Law: Our Vital Role in Veterans Law

    Total disability based on individual unemployability (TDIU) is a VA benefit that allows veterans to receive benefits at the 100 percent rate if their service-connected disabilities prevent them from obtaining and maintaining substantially gainful employment.

    Who We Are: Chisholm Chisholm & Kilpatrick (CCK Law) has argued many of the cases that define and clarify veterans disability law. Our attorneys serve in many leadership positions and have posted more than 2,500 blogs and 1,100 videos explaining veterans benefits. With 100+ individuals accredited by VA or admitted to practice before the U.S. Court of Appeals for Veterans Claims, CCK Law has recovered over $1 billion in compensation for 36,000+ clients since 1999. (Past results do not guarantee future outcomes.) Contact us to tell us about your case.

    What Is the Difference Between Schedular and Extraschedular TDIU?

    There are two ways to qualify for TDIU under VA’s regulation, 38 CFR § 4.16: schedular and extraschedular.

    Schedular

    There are two ways to qualify for schedular TDIU:

    1. The veteran has one service-connected disability rated at 60 percent or more.
    2. The veteran has two or more disabilities with one disability rated at 40 percent or more, with a combined rating of 70 percent or more.

    Get an estimate from our disability calculator if you are not sure what your combined disability rating is.

    Under this regulation, there are multiple ways to meet the requirement that one disability be rated at 60 percent in the first criteria, or the 40 percent in the second criteria. Disabilities can be combined to reach those percentage requirements through one or more of these ways:

    • The veteran has disabilities of one or both upper extremities, or one or both lower extremities, including the bilateral factor.
    • Their disabilities result from a common etiology or a single accident (e.g., a car crash in service).
    • The disabilities affect a single body system, such as the digestive or respiratory system.
    • The disabilities are considered to be injuries incurred in action.
    • The disabilities were incurred as a prisoner of war.

    Extraschedular

    The second way to qualify is on an extraschedular basis. Extraschedular means that a veteran’s service-connected conditions prevent them from securing and maintaining substantially gainful employment, but they do not meet either of the criteria for schedular TDIU. Extraschedular TDIU does not have any rating requirement.

    The main difference in the process of being considered for schedular and extraschedular TDIU is that if a veteran does not meet the criteria for schedular TDIU, their case will be referred to the Director for Compensation Service for extraschedular consideration.

    The Director will look at the veteran’s case and write an opinion. The opinion will decide whether the veteran’s conditions prevent them from securing and following substantially gainful employment. If a veteran receives an unfavorable opinion from the Director, it is not the end of the road. A veteran advocate or attorney can argue against the Director’s opinion if the veteran finds it to be inadequate.

    Can I Work and Receive TDIU?

    It depends. VA specifies that entitlement to TDIU is determined by whether the veteran can secure and maintain substantially gainful employment. VA does not define the term “substantially gainful employment,” but the Courts have determined that a veteran’s employment is substantially gainful if it provides an annual income above the federal poverty threshold. If the veteran’s earnings are below the poverty threshold, their employment is considered marginal, and they may still be considered eligible for TDIU.

    If a veteran is working and their income is above the poverty threshold, they may still qualify for TDIU if they work in what is called a protected work environment. A protected work environment can include working in a family business or sheltered workshop.
