CPT 43235 | Diagnostic Flexible Transoral EGD (Esophagogastroduodenoscopy)

CPT code 43235 describes the procedure of diagnostic flexible transoral esophagogastroduodenoscopy.

What Is CPT Code 43235?

CPT 43235 describes a procedure called “Esophagogastroduodenoscopy, flexible, transoral.” This procedure is also known as an upper endoscopy or EGD.

Code 43235 is specifically for diagnostic flexible transoral esophagogastroduodenoscopy, including collecting specimen(s) by brushing or washing.

The provider passes a flexible endoscope through the mouth and throat into the esophagus, stomach, and duodenum.

The endoscope is equipped with a camera and light source. This allows the doctor to look at the lining of the esophagus, stomach, and the beginning of the small intestine to detect any abnormal conditions. It includes collecting samples by brushing or washing the area for laboratory analysis if needed.


The CPT book describes CPT code 43235 as: “Esophagogastroduodenoscopy, flexible, transoral; diagnostic, including the collection of specimen(s) by brushing or washing, when performed (separate procedure).”


Following the administration of anesthesia, the healthcare provider begins the procedure by carefully inserting a specialized scope into the patient’s mouth.

This scope is designed to navigate the complex anatomy of the upper gastrointestinal tract. It is passed through the pylorus, the muscular ring that separates the stomach from the small intestine, and into the duodenum, the first part of the small intestine.

Once the scope is securely in place, the provider carefully examines the structures of the duodenum, including the walls and any potential abnormalities.

This examination is performed using advanced imaging technology built into the scope, allowing a clear and detailed view of the examined area.

If necessary, the provider may also collect specimens from the duodenum for further analysis.

This can be done by gently brushing or washing the area with a saline solution and collected and sent to a laboratory for microscopic examination. The procedure is painless and done with the patient’s comfort and safety.

After the examination and any necessary specimens have been collected, the provider slowly and carefully withdraws the scope from the patient’s mouth. The procedure is complete, and the patient will be monitored for any potential complications or adverse reactions to the anesthesia before discharge.
