What it is
A diagnostic mammogram of one breast is an X-ray exam done to check a specific concern, such as a lump, pain, nipple discharge or an unclear result on a screening mammogram. It usually takes more images than a screening exam.
What the price covers
The hospital price usually covers the imaging, including computer-aided detection when used. The radiologist's reading is often billed separately, and 3D mammography (tomosynthesis) or a follow-up ultrasound is billed under other codes.
