# CPT 36475

> Medicare paid $1,404.97 for CPT 36475 in the office (non-facility) setting and $291.96 in a facility under the Q4 2020 Physician Fee Schedule, effective October 2020. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2020, when it decreased 4.0%.

## What it is

Closure of a leaking superficial leg vein from the inside using heat. A catheter is slid into the vein through a small puncture, numbing fluid is placed around the vein to protect nearby tissue, and radiofrequency energy heats the vein wall so it shrinks and seals; blood then reroutes through healthy deep veins. What sets this entry apart from its neighbours is the energy source, radiofrequency rather than laser or a chemical agent. It describes the first vein treated in a leg during the session, with a companion code for each further vein.
