What 36557 covers

This service places a central venous catheter through a subcutaneous tunnel, with the catheter exiting the skin and no implanted port or pump. It is commonly used for young children needing durable access for treatments such as chemotherapy, parenteral nutrition, or prolonged intravenous therapy. Surgeons and other qualified proceduralists may perform the placement in a hospital or surgical setting.

Select the code based on the patient’s age on the date of the procedure and whether the device is tunneled and lacks a port or pump. Documentation should identify the patient’s age, catheter type, tunneled route, and placement details. CMS assigns a 10-day global period, so related postoperative visits during that period are included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 applies to a bilateral procedure, 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.

36557 billing questions

How does this code differ from 36558?

Both describe tunneled central venous catheter placement without a port or pump. Use 36557 for a patient younger than five and 36558 for a patient age five or older.

Can this code be used for an implanted port?

No. It describes a tunneled catheter without a subcutaneous port or pump; code selection changes when the implanted device includes a port.

What documentation supports reporting 36557?

Document the patient’s age on the procedure date, the tunneled catheter placement, and that the device has no subcutaneous port or pump.

Are related postoperative visits separately paid during the global period?

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

When is an assistant at surgery payable?

CMS allows assistant-at-surgery payment only when the record documents medical necessity. Co-surgeons and team surgery are not permitted for this code.

How are other procedures in the same session paid?

The highest-valued procedure is paid in full, and other procedures in that session are paid at 50%. For a bilateral procedure reported with modifier 50, CMS pays at 150%.

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.
