Maryland Medical Assistance Program and Health Insurance - Required Coverage for Calcium Score Testing

HB 666 requires Maryland's Medicaid program (Maryland Medical Assistance Program) and most health insurance plans to cover calcium score testing for individuals with specific heart disease risk factors. It directly affects people with diabetes, high blood pressure, high cholesterol, or a family history of early heart disease - requiring coverage if they have at least three of these risk factors. The law mandates coverage starting January 1, 2026, for Medicaid and all health insurance policies issued or renewed after that date. This change applies to insurers, nonprofit health plans, health maintenance organizations, and managed care organizations operating in Maryland. The bill does not alter coverage for other medical services but specifically adds calcium scoring to required benefits.
