CPT® Code 89140

Deleted

Gastric intubation, aspiration, and fractional collections (eg, gastric secretory study); 2 hours including gastric stimulation (eg, histalog, pentagastrin)

The procedure described by CPT® Code 89140 involves gastric intubation, aspiration, and fractional collections, which are essential components in conducting a gastric secretory study. This procedure entails the insertion of a tube through the patient's nose or mouth, extending it into the stomach. The primary objective is to draw fluid from the stomach over a specified duration, which in this case is two hours. During this time, the stomach may be stimulated using agents such as histalog or pentagastrin, which are pharmacological substances that enhance gastric secretory activity. This stimulation is crucial for obtaining accurate measurements of gastric secretions, which can provide valuable insights into the digestive process and the functionality of the stomach. It is important to note that if the test is performed over a different duration or without stimulation, different CPT codes should be utilized, such as Code 89136 for a one-hour test or Code 89141 for a three-hour test with stimulation. Understanding these distinctions is vital for accurate coding and billing in medical practice.
