Question: How should I code for anesthesia during a transesophageal echocardiography (TEE) procedure with probe placement? Minnesota Subscriber Answer: It looks like your anesthesiologist is involved with providing anesthesia for 93312 (Echocardiography, transesophageal, real-time with image documentation (2D) (with or without M-mode recording); including probe placement, image acquisition, interpretation and report). The anesthesia crosswalk for 93312 and the subsequent TEE codes is 01922 (Anesthesia for non-invasive imaging or radiation therapy).
