CPT® Code 43754

The procedure described by CPT® Code 43754 involves gastric intubation and aspiration for diagnostic purposes, specifically focusing on obtaining a single specimen, such as for acid analysis. This process begins with the insertion of a gastric tube, which can be done through either the nose or mouth. When opting for nasal insertion, the physician examines both nostrils to determine which one is more open (patent) and suitable for the procedure. To facilitate the insertion and minimize discomfort, the patient's head is tilted backward, and a local anesthetic, typically viscous lidocaine, is applied to the selected nostril. The physician then estimates the necessary length of the tube to reach the stomach and marks it accordingly. The tube is carefully inserted into the nostril and advanced through the nasopharynx. To aid in the passage of the tube through the oropharynx and esophagus into the stomach, the patient may be instructed to sip water. Once the tube is in place, its proper positioning is confirmed by either instilling air into the stomach and listening for a rush of air or by aspirating gastric contents. The primary goal of this procedure is to perform a diagnostic aspiration, where a single specimen of gastric content is collected for further analysis. This procedure is distinct from CPT® Code 43755, which involves obtaining multiple fractional specimens for a more comprehensive evaluation of gastric secretions, often requiring the administration of various drugs to stimulate gastric secretion.
