Question: Is ultrasound guidance and/or fluoroscopy included in the procedure code when my urologist performs an ESWL? If not, can we also report the ultrasound guidance with 76998? New Hampshire Subscriber Answer: No, you cannot report 76998 (Ultrasonic guidance, intraoperative) or any other radiology guidance code with 50590 (Lithotripsy, extracorporeal shock wave). The fluoroscopy and ultrasound are included in the extracorporeal shock wave lithotripsy (ESWL) code and so are not separately billable services.
