What 51705 covers

This service covers replacing an existing cystostomy tube through an established suprapubic tract, rather than creating a new tract or placing a urethral catheter. A urologist or other qualified practitioner commonly performs the exchange in an office, clinic, or facility for a patient who requires ongoing bladder drainage. The procedure is simple when the existing tract allows a straightforward tube exchange without circumstances that make the change complicated.

Report one service for the exchange, supported by documentation identifying the existing tube, its removal and replacement, and the clinical circumstances showing a simple change. Use 51710 when the cystostomy tube change is complicated. The 0-day global period includes same-day preoperative and postoperative care. If other procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
