What 36590 covers
This service removes an implanted central venous access device that has a subcutaneous port or pump connected to a tunneled catheter. The clinician opens the port pocket, frees and removes the reservoir and catheter, and closes the incision. It is commonly performed by a surgeon or interventional radiologist when a port is no longer needed after treatment, or when the device requires removal because of a clinical problem. Procedures may take place in a hospital, ambulatory surgery center, or office setting.
Report 36590 when the port or pump and its tunneled catheter are removed; 36589 is for a tunneled catheter without a subcutaneous port or pump. Documentation should identify the device removed and support the reason for removal. The service has a 10-day global period, which includes related postoperative visits during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction. An assistant at surgery is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

36590 billing questions
How do I choose between 36590 and 36589?
Use 36590 when the removed tunneled device includes a subcutaneous port or pump. Use 36589 for removal of a tunneled central venous catheter without a port or pump.
Does 36590 cover removal of both the port and catheter?
Yes. The service is removal of the port or pump together with its tunneled catheter; do not report 36589 for the catheter portion of the same device removal.
Should I report 36590 when the port is replaced?
When the service is replacement of a tunneled central venous access device with a port or pump, consider the applicable replacement code, such as 36581, rather than reporting removal alone.
Can an assistant surgeon be reported?
Medicare payment for an assistant at surgery is limited to cases with documented medical necessity. Co-surgeons and team surgery are not permitted for this code.
What postoperative care is included?
Related postoperative visits for 10 days are included in the global period. The record should support the device removed and the clinical reason for removal.
What if the goal is to clear an obstruction but keep the device?
Mechanical removal of obstructive material from a central venous device is a different service from removing the port and catheter. Codes 36595 and 36596 describe that type of intervention.
