Bill Summary: SB 1648

• Expands mammography and breast cancer screening coverage requirements for insurance policies by adding coverage for ultrasound, magnetic resonance imaging, and breast tomosynthesis based on medical necessity and risk factors.

• Adds breast tomosynthesis to the definition of "screening mammography" in Arizona Revised Statutes section 30-651 to include three-dimensional x-ray imaging of the breast.

• Updates mammography screening guidelines to allow coverage at medically necessary ages and intervals determined by a woman's healthcare provider, rather than limiting coverage to specific age ranges.

• Requires coverage for additional breast imaging when a screening mammogram reveals abnormalities, patient presents with symptoms, or a healthcare provider deems imaging medically necessary based on prior diagnostic results.

• Applies these coverage requirements uniformly across multiple types of insurance contracts, including hospital service corporations, medical service corporations, disability insurance policies, and blanket disability policies.
