# CPT 74018

> Medicare paid $27.72 for CPT 74018 in the office (non-facility) setting and $27.72 in a facility under the Q2 2018 Physician Fee Schedule, effective April 2018. These are the national allowed amounts before the ~2% sequestration cut and before locality (GPCI) adjustment.

## What it is

One plain radiograph of the abdomen, usually taken with the patient lying on their back. It is the briefest abdominal film: a single picture that shows the gas pattern in the bowel, the outlines of some organs, and anything dense enough to stand out, such as certain stones, surgical clips, or a swallowed object. Studies using two views, three or more views, or a full acute-abdomen series with a chest film are coded separately.
