The schedule doesn’t include every type of gastrointestinal illness or disease. When assigning a disability rating for disabilities not in the schedule, the VA compares your symptoms to those of the rating table’s most similar disability.
You will be assigned an analogous or equivalent code if your specific diagnosis isn’t listed. These codes are used to match your condition as closely as possible with one already recognized in the Veterans Affairs Schedule for Rating Disabilities.
For example, there is no rating schedule for the diagnosis of diverticulitis. This condition causes pockets of inflammation or infection in the digestive tract, leading to abdominal pain. Instead, the VA may use the rating schedule for irritable bowel syndrome or other similar conditions to determine your payments.
