What 36565 covers

This service places two catheters through a subcutaneous tunnel into central venous access, without an implanted port or infusion pump. It is used when the patient needs two separate catheter pathways for ongoing access, such as for complex infusion or dialysis needs. A surgeon or interventional radiologist typically performs the insertion in a hospital or other procedural setting. The code is for patients age five years or older; the number of catheters and the absence of a port or pump distinguish it from related insertion services.

Report one unit for the insertion service involving both catheters, rather than a separate unit for each catheter. The procedure note should identify the patient’s age, the two catheters placed, their tunneled route, and that no port or pump was implanted. CMS assigns a 10-day global period, so related postoperative visits during those 10 days are included. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. 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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

36565 billing questions

How does this differ from 36558?

This code is for a patient age five years or older who needs two tunneled catheters without a port or pump. 36558 describes the corresponding single-catheter service.

Can I report one unit for each catheter?

No. The service is reported once for the insertion involving two catheters; do not report a separate unit for each catheter.

When is 36566 a better fit?

Use 36566 when the two-catheter insertion includes a subcutaneous port. This code describes two catheters without a port or pump.

Are related postoperative visits separately payable during the global period?

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

Can an assistant or another surgeon be reported?

Assistant-at-surgery payment is allowed only when medical necessity is documented. CMS does not permit co-surgeon or team-surgery reporting 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 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.
