What it is

A diagnostic mammogram of both breasts is an X-ray exam done to look into symptoms or to follow up on something seen on an earlier mammogram. It uses more targeted views than a routine screening exam.

What the price covers

The hospital price usually covers the imaging of both breasts, including computer-aided detection when used. The radiologist's reading is often billed separately, and 3D mammography or a breast ultrasound is billed under other codes.
