Esophagogastroduodenoscopy, flexible, transoral; diagnostic, including collection of specimen(s) by brushing or washing, when performed (separate procedure)

AI EXPLANATION: A diagnostic upper endoscopy, often referred to as an EGD, is a visual examination of the lining of the upper digestive tract. A physician guides a thin, flexible tube equipped with a small light and camera through the mouth and down into the esophagus, stomach, and initial segment of the small intestine. During the procedure, the doctor can carefully check for irritation, ulcers, or growths, and may collect small fluid or tissue cell samples using a tiny brush or washing wash technique for lab testing.
