What 36580 covers
This service replaces a non-tunneled, centrally inserted venous catheter through the existing venous access, rather than establishing access at a new site. It is commonly performed in a hospital by an interventional radiologist, surgeon, or other qualified proceduralist when a short-term central line needs complete replacement, such as because it is malfunctioning or damaged. The replacement catheter remains a central venous device; this code is not for a tunneled catheter, a PICC, or a device with an implanted port or pump.
Report the service when documentation identifies the existing line as non-tunneled, supports complete catheter replacement, and shows that the same venous access was used. The code has a 0-day global period, so same-day preoperative and postoperative care is included. Modifier 50 is inappropriate for this service. Medicare does not pay for an assistant at surgery; co-surgeons and team surgery are not permitted for this code.

36580 billing questions
How does 36580 differ from 36581?
36580 is for complete replacement of a non-tunneled central venous catheter through the same access. 36581 is the related replacement code for a tunneled catheter.
Can 36580 be used when the new catheter is placed at a different site?
No. The code describes replacement through the same venous access; documentation should establish that the existing access was used.
Is a repair reported as a replacement?
No. 36580 represents complete catheter replacement, not repair of an existing catheter. The record should support replacement of the catheter rather than correction of a limited defect.
What documentation supports 36580?
Document that the catheter was non-tunneled and centrally inserted, that the replacement was complete, and that the same venous access was used. Include the clinical reason the line required replacement.
What global-period and modifier rules affect this code?
The 0-day global period includes same-day preoperative and postoperative care. Modifier 50 is inappropriate; Medicare also does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.
