Monitoring of Upper GI Oxygen Saturation, Endo, New Tech 7

This code describes the direct measurement of oxygen saturation within the upper gastrointestinal (GI) tract, specifically the esophagus, stomach, or duodenum. This monitoring is performed using an endoscopic approach, where a specialized probe is inserted through a natural orifice (e.g., mouth) or an artificial opening to visualize and assess tissue oxygenation. This represents a novel technology for assessing GI perfusion.

This code is appropriate for procedures involving the real-time, endoscopic assessment of oxygen saturation in the upper GI tract using new technology. This may be performed in critically ill patients, those with suspected GI ischemia, or during complex surgical procedures to monitor tissue viability. It is used when the intent is to monitor oxygen levels directly within the GI lumen.
