Is this simple 51705 (75984) or complex 51710 (75984)? "Fluoroscopically-guided exchange of suprapubic catheter. Procedure and Findings: The procedure was performed in the VIR suite following informed consent. A time-out was performed, and the correct procedure site was initialed by the radiologist. Preprocedure antibiotics were not indicated. With the patient in the supine position, the lower abdomen and the existing tube were prepped and draped in the usual sterile fashion. All elements of maximal sterile barrier technique were followed including: cap, mask, sterile gown, sterile gloves, a large sterile sheet, hand hygiene, and 2% chlorhexidine for cutaneous antisepsis (or acceptable alternative antiseptics). The position of the tube was assessed with fluoroscopy and contrast injection. The tip of the tube was in the urinary bladder. The retention balloon was deflated. The catheter was removed. The new 16 French suprapubic catheter was advanced through the existing tract into the urinary bladder lumen under direct fluoroscopic guidance. There was immediate return of the urine."
