Code 91299 covers specialized digestive system diagnostic tests that don't fit standard procedure categories, such as experimental motility studies or novel imaging techniques. Gastroenterologists typically use this code for patients requiring uncommon diagnostic approaches when standard tests are inadequate. This unlisted code requires detailed documentation and prior authorization, as reimbursement varies significantly based on the specific procedure performed and payer policies.
