Outpatient: lowest $178.75, median $178.75, highest $178.75.

Both sides : lowest $73.45, median $73.45, highest $73.45.

The two groups are not comparable and are not averaged together: a price for both sides of the body covers twice the work. Merging them is how a single published "median" ends up far above what one side actually costs.

As an inpatient, the same code is billed by 1 facility here, median $178.75. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

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.
