Excerpt from Hill and Ponton’s The goal for many veterans is to get to a 100 percent disability rating, but this is not always possible through the rating schedule due to an individual’s particular conditions. But, there is another way to be awarded a 100 percent rating: total disability based on individual unemployability (TDIU). Under 38 C.F.R. s. 4.16, a total disability rating may be assigned if a person who fails to meet the schedular rating is, nevertheless, unable to obtain and maintain a substantially gainful occupation. TDIU is not a separate claim for benefits, but is instead part of the rating process.
