About 36581: Tunneled central venous catheter replacement with imaging
Reports complete replacement of a tunneled central venous catheter without an implanted port, using the existing venous access with imaging guidance.
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.

36581 billing questions
How is this different from 36578?
36581 includes imaging guidance with supervision and interpretation for the complete tunneled-catheter replacement. 36578 is the corresponding replacement without imaging guidance.
Can 36581 be reported for a catheter repair?
No. It represents complete catheter replacement. For repair of a catheter that remains in place, consider the applicable repair code, such as 36575 or 36576.
Is imaging guidance separately reported?
Imaging guidance and its associated supervision and interpretation are included in 36581. Do not report them separately for the same replacement service.
When is 36582 more appropriate?
Use 36582 for complete replacement of a tunneled central venous access device with a subcutaneous port or pump. Code 36581 is for a catheter without a port or pump.
What documentation supports the replacement?
Document that the catheter is tunneled and centrally inserted, that the entire catheter was replaced through the existing venous access, and that imaging guidance was used.
Can modifier 50 be used for bilateral replacement?
No. CMS identifies bilateral adjustment as inappropriate for this code; modifier 50 should not be used.
