CPT code 36585: Device replacement, ported peripheral access device2026 Medicare rate & RVUs

Medicare pays $1,493.35 for 36585 nationally in the office and $293.93 in a hospital or facility. Local office rates run $1,289.99–$2,067.12.

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
