# CPT 36561

> Medicare paid $1,113.09 for CPT 36561 in the office (non-facility) setting and $340.91 in a facility under the Q1 2021 Physician Fee Schedule, effective January 2021. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This is a 0.8% increase from the previous quarter.

## What it is

Placement of an implanted port: a small reservoir with a tough silicone top is buried in a pocket under the skin, usually on the upper chest, and joined to a catheter that is tunneled beneath the skin and threaded into a large central vein near the heart. Nurses use it by pushing a special needle through the skin into the reservoir, so nothing dangles outside the body between treatments and the patient can shower and swim normally. This entry covers the port and its catheter placed together as one device, in patients aged five and older.
