# CPT 92020

> Medicare paid $27.28 for CPT 92020 in the office (non-facility) setting and $21.53 in a facility under the Q2 2017 Physician Fee Schedule, effective April 2017. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2017, when it increased 1.6%.

## What it is

An examination of the angle where the iris meets the cornea, the drainage channel through which fluid leaves the front of the eye. Because that angle cannot be seen directly, the doctor places a special mirrored contact lens on the numbed eye and views the structures through it. The findings show whether the angle is open, narrow, or closed, and whether scarring, pigment, or abnormal vessels are present. It is a distinct diagnostic procedure done in addition to the eye exam itself, not part of a routine look at the eye.
