What 36581 covers

This service replaces a tunneled, centrally inserted venous catheter in its entirety through the existing venous access, without a subcutaneous port or pump. Imaging guidance and its associated supervision and interpretation are included. It is commonly performed by an interventional radiologist or another physician experienced in vascular access, often for a patient whose long-term infusion or hemodialysis catheter is damaged, malfunctioning, or due for exchange. The code describes replacement, not repair of a catheter that remains in place or placement through a new venous access.

Report the code when documentation supports a complete exchange of the tunneled catheter through the same access and identifies the imaging-guided service. The procedure note should establish the catheter type, absence of a port or pump, the existing access used, and the replacement performed. CMS assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures occur in one 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. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
