CPT® Code 43290

The procedure described by CPT® Code 43290 refers to a flexible esophagogastroduodenoscopy (EGD) performed transorally, which includes the deployment of an intragastric bariatric balloon. This procedure is primarily indicated for patients who are struggling with obesity and have not achieved significant weight loss through dietary changes or pharmacological treatments. During the EGD, a flexible endoscope is inserted through the mouth, allowing the physician to visualize the esophagus, stomach, and duodenum. The procedure involves suctioning any liquid contents from the stomach, insufflating the stomach for better visibility, and inspecting the gastrointestinal tract for abnormalities. The deployment of the intragastric balloon is a critical component of this procedure, as it aids in weight loss by occupying space in the stomach, thereby promoting a feeling of fullness. This intervention is typically performed under sedation to ensure patient comfort and cooperation throughout the process.
