# CPT 93458

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 increased 3.2%.

## What it is

A diagnostic cardiac catheterization done through an artery in the wrist or groin. A thin catheter is steered up to the heart, contrast dye is injected into the coronary arteries and filmed so narrowings show up as constrictions in the dye column, and the catheter is also passed into the left ventricle to record pressures and, when performed, to film the main pumping chamber. This is the standard way to establish whether chest pain comes from blocked coronary arteries and how bad the blockages are.
