Supporting Premature Infant Nutrition Act of 2025

This bill requires Medicaid, Children's Health Insurance Program (CHIP), and private health plans to cover human milk fortifier - specialized nutritional products made from donor human milk - without cost-sharing for eligible premature infants. It directly affects infants under 1 year with specific medical needs, such as birth at 34 weeks or less, birth weight under 1,800 grams, or certain health conditions requiring this fortifier. Key provisions mandate no deductibles or copays for this coverage starting January 1, 2026, and define eligibility criteria for healthcare providers to determine medical necessity. The law applies broadly across federal health programs and private insurance, ensuring access to this nutrition support for qualifying infants.
