# CPT 73700

> Medicare paid $180.45 for CPT 73700 in the office (non-facility) setting and $180.45 in a facility under the Q2 2016 Physician Fee Schedule, effective April 2016. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment. This price has been unchanged since Q1 2016, when it increased 0.2%.

## What it is

A CT scan of a lower limb - hip region, thigh, knee, lower leg, ankle, or foot - performed without injecting contrast dye. CT builds cross-sectional slices from X-rays, so it shows bone detail far better than a plain film and can reconstruct the anatomy in three dimensions. This is the plain version of the study; scans done with intravenous contrast, or without and then with contrast in the same sitting, are coded separately.
