What 36566 covers

This service covers placement of two tunneled central venous catheters without an implanted port or pump in a patient age five years or older. The operator establishes central venous access and creates a subcutaneous tunnel for each catheter. Surgeons and interventional radiologists commonly perform the procedure in a hospital or other procedural setting for patients needing ongoing central access, such as for repeated infusions or other long-term therapy. The code describes two catheters, not a single catheter with two lumens.

Select this code when the record supports the patient’s age, two catheter placements, tunneled route, and absence of a port or pump. Document the indication, access and tunneling performed, and final 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 subject to the standard 50% reduction. 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.

36566 billing questions

Does this code describe a double-lumen catheter?

No. It describes placement of two catheters. A single catheter does not become two catheters because it has multiple lumens.

How does this differ from 36558?

Both describe tunneled central venous catheter placement without a port or pump in patients age five or older. 36566 is for two catheters; 36558 is for one.

Can this be reported when a subcutaneous port is placed?

No. This code is for tunneled catheters without a port or pump. Port placement belongs to the applicable port-insertion code.

What documentation supports reporting two catheters?

The procedure note should establish that two separate catheters were inserted and tunneled, rather than one catheter with multiple lumens.

What postoperative care is included?

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

When is assistant-at-surgery payment allowed?

CMS allows assistant-at-surgery payment only when the record documents medical necessity.

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.
