What 36583 covers
This service replaces a tunneled central venous catheter through the existing venous access. It is used for long-term central access, such as a tunneled catheter used for dialysis, chemotherapy, or prolonged infusion, when the existing catheter needs complete exchange. Interventional radiologists, surgeons, and other qualified physicians typically perform the procedure in a hospital or ambulatory procedural setting. The service concerns a tunneled catheter, not a port-based device or a PICC.
Report the code when the physician completes an exchange through the same access, rather than simply repairing the existing catheter or establishing new access. Documentation should identify the catheter, the reason for exchange, the access used, and the replacement performed. The code has a 10-day global period, which includes related postoperative visits during that period. When multiple procedures occur in the same 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.

36583 billing questions
How does this differ from 36581 or 36582?
Choose among the tunneled-catheter replacement codes based on the specific device and service described by the applicable code. Code 36582 is for replacement of a tunneled device with a subcutaneous port; confirm the distinction between 36581 and 36583 in the current code descriptor.
Can catheter removal be billed separately during the exchange?
This code represents a complete replacement through the same access, rather than a standalone removal followed by a separately coded insertion. The record should support that a complete exchange was performed.
When is repair more appropriate than replacement?
Use a repair code when the existing tunneled catheter is repaired rather than completely exchanged. Codes 36575 and 36576 distinguish repair services by device type.
Does modifier 50 apply if two catheters are replaced?
No. CMS identifies bilateral adjustment as inappropriate for this code. Document each service performed and apply the multiple procedure rule when procedures are performed in the same session.
What postoperative care is included?
Related postoperative visits during the 10-day global period are included in the procedure's payment.
When may an assistant-at-surgery be paid?
Assistant-at-surgery payment is available only when the record documents medical necessity. Co-surgeons and team surgery are not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
