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

This code describes the direct measurement of oxygen saturation within the lower gastrointestinal tract, such as the colon or rectum. This monitoring is performed using an endoscopic approach, where a scope is inserted through a natural body opening (e.g., anus) or an artificial opening (e.g., stoma) to visualize and assess tissue oxygenation. It represents a novel diagnostic technique for evaluating gut perfusion.

This code is appropriate when a physician performs endoscopic monitoring of lower GI oxygen saturation to assess tissue viability or ischemia. This may be indicated in patients with suspected bowel ischemia, inflammatory bowel disease, or during complex surgical procedures involving the lower GI tract to guide clinical decision-making.

• Ensure documentation clearly specifies "lower GI" and "oxygen saturation" as the monitored physiological function.
