HB 1364 Maryland House of Delegates · 2026 Regular Session

Public Health - Mammograms - Arterial Calcification Notice

HB 1364 requires mammography centers in Maryland to include a specific notice about breast arterial calcification in patients' screening results letters, starting October 1, 2026. This applies to facilities performing mammography testing (like hospitals, clinics, or radiology practices), excluding federal VA facilities. The notice informs patients that arterial calcification - common but potentially linked to higher cardiovascular risk - should be discussed with their physician to assess heart health needs. It does not change existing federal requirements for breast density notices but adds this new patient awareness element to standard mammogram results.

MINOR

This bill was amended to add a new requirement for mammography centers to include a specific notice about breast arterial calcification in patient screening results, alongside the existing notice about breast density. The amendment also reorganized the statutory text to clarify that the new notice requirement does not create a legal standard of care or basis for a lawsuit against medical providers.

Scope change

The bill now applies to all mammography centers performing screenings, requiring them to provide two distinct notices: one for breast density and a new one for breast arterial calcification.

REQUIREMENT

Added a mandatory notice informing patients that breast arterial calcification is a common finding that may indicate an increased risk of cardiovascular disease and should be discussed with a physician.

Reorganized the statutory language to explicitly state that the new notice requirement does not create a standard of care, obligation, or duty that provides a basis for a cause of action.

TECHNICAL

Updated the bill's metadata to reflect that it was adopted by the House and includes a favorable committee report with amendments.
