Creates provisions relating to insurance coverage of preventative health care services

HB 3452 requires health insurance plans sold in the state to cover specific preventative health services without cost-sharing (like copays or deductibles) starting January 1, 2026. It mandates coverage for evidence-based services rated A or B by the U.S. Preventive Services Task Force, CDC-recommended immunizations, and preventative care outlined in Health Resources and Services Administration guidelines. The law allows limited exceptions, such as applying high-deductible plan requirements to certain services or imposing cost-sharing for out-of-network providers. This directly affects health insurers and policyholders by ensuring no out-of-pocket costs for these recommended preventative services.
