Supporting Premature Infant Nutrition Act of 2025

The Supporting Premature Infant Nutrition Act of 2025 would require no-cost coverage for a specific donor-derived product called a human milk fortifier across federal health programs and private plans. Specifically, starting January 1, 2026, the bill would (1) add human milk fortifier to Medicaid and CHIP as mandatory medical assistance with no cost sharing, and (2) require group health plans and health insurance issuers offering group or individual coverage to cover human milk fortifier with no cost sharing. The fortifier is defined as a donor human milk-derived product intended for infants under age one when a healthcare professional determines it is medically necessary—primarily for very premature or very low birth weight babies or for certain conditions where fortification aids health outcomes. The act sets out who can determine medical necessity (specified professionals) and clarifies that no copays, deductibles, or coinsurance may be charged for this product. The bill also provides a phased effective date framework for states that need to adjust state laws or plans.
