What 36585 covers
This service replaces the complete port-containing device used for central venous access when the access enters through a peripheral vein. The replacement uses the existing venous route; it is distinct from exchanging a standard PICC or replacing a centrally inserted tunneled catheter. Vascular access specialists, interventional radiologists, and surgeons may perform it in a hospital or procedural setting, commonly when the existing device requires complete replacement.
Report the code when documentation identifies a port-containing peripheral access device and supports complete replacement through the existing venous route. The record should distinguish this device from a non-ported PICC and from a centrally inserted catheter. Related postoperative visits during the 10-day global 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 multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

Is the 10-day postoperative care separately reportable?
