What 36561 covers

This service places a central venous catheter through a tunnel under the skin and connects it to a port implanted beneath the skin. The port provides repeat access for treatments such as chemotherapy, long-term intravenous medication, or blood sampling. Surgeons and interventional radiologists commonly perform the procedure in hospital procedural settings and, in some cases, office settings. The patient must be at least five years old, and the device must include a subcutaneous port.

Report the code for initial placement, not for a non-tunneled line, a tunneled catheter without a port, or replacement of an existing device. The operative report should support the patient’s age, tunneled route, port placement, and reason for access. Imaging guidance used for placement is included in the procedure. CMS assigns a 10-day global period, including related postoperative visits during that period. In a session with multiple procedures, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 for a bilateral procedure is paid at 150%. An assistant at surgery is paid only with 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.

What documentation supports reporting 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.
