Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
