CPT 77066 is a diagnostic mammogram of both breasts: extra views taken because of a symptom, a lump, or something seen on a screening mammogram. Unlike screening, it is not covered as free preventive care, and it is usually priced higher because a radiologist reviews the images while you wait and may add an ultrasound.

What the price covers

The hospital's price is the technical fee for the mammography unit, technologist and additional views. The radiologist's reading is billed separately. A breast ultrasound (76641 or 76642), often done in the same visit, is a separate code and charge.

Why prices vary

Diagnostic mammogram prices vary several times between hospitals in the same area. Breast centers attached to large systems tend to list the highest gross charges; community hospitals and outpatient imaging centers list lower. Cash prices are usually well below gross.
