Vascular access

About 36558: Tunneled central venous catheter insertion

Reports placement of a tunneled central venous catheter without an implanted port or pump in a patient age 5 years or older.

This service places a central venous catheter through a subcutaneous tunnel, with the catheter entering a central vein and exiting at a separate skin site. It is used when a patient needs longer-term venous access, such as for extended infusion therapy or repeated treatment. Surgeons and interventional radiologists commonly perform the procedure in a hospital operating room or interventional suite; it may also be performed in another appropriate procedural setting.

Report 36558 for a patient age 5 years or older when the catheter is tunneled and no subcutaneous port or pump is implanted. The record should support the patient’s age, the need for central access, and the tunneled catheter placement. CMS assigns a 10-day global period, including 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 reduced. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

36558 billing questions

How does 36558 differ from 36557?

Both report a tunneled central venous catheter without a port or pump. 36558 is for patients age 5 years or older; 36557 is for younger patients.

When should 36561 be considered instead?

Use 36561 when the tunneled catheter is placed with a subcutaneous port in a patient age 5 years or older. Code 36558 describes a catheter without an implanted port or pump.

Can tunneling be reported separately from catheter insertion?

No separate service is represented by the tunnel itself here; 36558 reports placement of the tunneled catheter.

What postoperative care is included?

Related postoperative visits during the 10-day global period are included in the procedure payment.

How does CMS handle multiple procedures in the same session?

CMS pays the highest-valued procedure in full and reduces the other procedures to 50% when they are performed in the same session.

What documentation supports an assistant-at-surgery claim?

The record must document medical necessity for the assistant. CMS does not permit co-surgeons or team surgery for this code.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
