our office performs outpatient surgery for varicose veins -we were advised that our anesthesiologist could bill for preoperative clearance under CPT 99215 and preoperative Duplex Ultrasound CPT 93971.This information was given to us by another medical practice that also performs surgery in the office - unfortunately, most of the insurance co's have denied these two because they are not considered separate and billable. Our anesthesiologist also performs Monitored Anesthesia Care CPT 01260 and to provide preoperative clearance should be a separate situation, is this not true? We could also use another E/M code 99214 Also, depending on the insurance co, we use pos 11 or 24 so Im not clear as to the pos for the E/M and Ultrasound either.
