CPT® Code 43242

Esophagogastroduodenoscopy, flexible, transoral; with transendoscopic ultrasound-guided intramural or transmural fine needle aspiration/biopsy(s) (includes endoscopic ultrasound examination of the esophagus, stomach, and either the duodenum or a surgically altered stomach where the jejunum is examined distal to the anastomosis)

The procedure described by CPT® Code 43242 involves a comprehensive examination of the upper gastrointestinal (UGI) tract, specifically targeting the esophagus, stomach, and either the duodenum or the jejunum in cases where the stomach has been surgically altered. This procedure is performed using a flexible endoscope, which is a thin, tube-like instrument equipped with a light and camera, allowing for direct visualization of the internal structures. The examination is enhanced by the use of transendoscopic ultrasound (EUS), which provides detailed imaging of the surrounding tissues and organs. During the procedure, fine needle aspiration or biopsy may be conducted to obtain tissue samples from any identified lesions or abnormalities. This is crucial for diagnosing various gastrointestinal conditions, as it allows for the evaluation of potential malignancies or other pathologies. The use of anesthetic spray ensures patient comfort by numbing the mouth and throat, facilitating the insertion of the endoscope. Overall, this procedure combines diagnostic imaging with therapeutic capabilities, making it a vital tool in the assessment and management of upper GI disorders.
