How could the new Maryland law on BAC reporting affect the state's healthcare oversight?
Maryland must now enforce a new law requiring mammography centers to report BAC findings. The passage of House Bill 1364 requires Maryland mammography centers to inform patients when a mammogram shows breast arterial calcification (BAC). This new state law, which took effect on October 1, 2026, mandates that centers add a specific notice to the results letter patients already receive under federal rules. The state must now oversee compliance across all covered facilities, including hospitals, clinics, and radiology practices. Furthermore, the Maryland Department of Health retains the authority to update this notice through regulations if medical evidence changes.

BAC is a calcium buildup in the breast's blood vessels that research has linked to higher heart disease risk. The finding is common and does not signal breast cancer.

Why it matters
The enactment of this law represents a significant regulatory shift in Maryland's public health landscape. By mandating the reporting of BAC, the state is using existing screening procedures to flag women who may benefit from closer attention to their heart risk, aligning with the goal of addressing heart disease, which is the leading cause of death for U.S. women.
This requirement places a new administrative and regulatory burden on the state's healthcare infrastructure. While the law does not require insurers to cover follow-up tests, the state must manage the implementation and oversight of this new reporting standard across all covered mammography centers.
