The Supporting Premature Infant Nutrition Act of 2025 would require no-cost coverage of human milk fortifier in Medicaid and CHIP, and extend that no-cost coverage to private group and individual health plans. It defines what counts as human milk fortifier, sets medical-necessity criteria, and prohibits any deductible, copayment, or coinsurance for the fortifier.
The changes apply beginning January 1, 2026, with a limited delay if state law is needed to implement the CHIP expansion. The bill also adds fortifier coverage to the Public Health Service Act framework for private insurers and set a clear implementation path for states and insurers to align with the new standard.
At a Glance
What It Does
Amends SSA titles XIX/XXI and the Public Health Service Act to require no-cost coverage of human milk fortifier, including definitions and scope, and to prohibit cost-sharing for this benefit.
Who It Affects
States administering Medicaid/CHIP, pregnant families with premature infants, NICUs, and private health plans (group and individual coverage).
Why It Matters
Establishes a federal baseline for neonatal nutrition, reducing out-of-pocket costs and barriers to fortifier access for vulnerable infants and their families.

What This Bill Actually Does
The bill amends multiple federal health programs to ensure that human milk fortifier is covered without any out-of-pocket costs. Under Medicaid, it expands mandatory coverage and includes fortifier in what counts as medical assistance, while prohibiting cost sharing.
It also adds fortifier to CHIP coverage, with the same no-cost rule and a built-in transition mechanism if a state needs to adjust its laws. For private plans, it creates a new requirement under the Public Health Service Act that group and individual insurance must cover fortifier with no cost sharing, effective for plan years beginning in 2026.
The fortifier itself is defined as a donor milk-derived product necessary for certain preterm infants, with explicit professional criteria for determining medical necessity. The bill also sets out definitions and a transitional path for states to implement these changes, including potential state-legislation delays for CHIP.
In short, starting in 2026, this is a unified federal push to remove cost barriers to essential nutrition for premature infants across public programs and private insurance.
The Five Things You Need to Know
The bill requires Medicaid to cover human milk fortifier without cost sharing starting January 1, 2026.
It defines human milk fortifier as a donor milk-derived product medically necessary for certain very preterm or low birth weight infants.
Cost sharing is prohibited for fortifier under Medicaid, with parallel prohibitions for private plans.
CHIP coverage is expanded to include fortifier with no cost sharing, with a transition rule if state legislation is needed.
Group health plans and health insurance issuers must cover fortifier with no cost sharing starting plan years beginning in 2026.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Medicaid coverage expansion for human milk fortifier
Section 2 amends Section 1902(a)(10)(A) to add the fortifier as a required component of minimum essential coverage, and Section 1902(a)(10)(C)(iv) to include fortifier in the Medically Needy framework. It also adds a new paragraph to Section 1937(b) authorizing States to require fortifier coverage in benchmark or benchmark-equivalent plans beginning in 2026.
Definitions and scope of fortifier
Section 1905 adds fortifier (defined as donor human milk-derived product) to the list of covered items, with a detailed definition of what qualifies as fortifier and who can determine medical necessity (a specified professional). This ensures clear eligibility criteria for coverage across programs.
Cost-sharing prohibitions under Medicaid
Sections 1916 and 1916A are amended to prohibit deductibles, coinsurance, or other cost-sharing for fortifier starting January 1, 2026. The amendments apply consistently across Medicaid and its cost-sharing framework to ensure no out-of-pocket burden for covered fortifier.
CHIP coverage expansion and transition
Section 2103 is amended to include fortifier as part of child health assistance with no cost sharing, and to apply the fortifier requirement to Title XXI programs starting January 1, 2026. There is a transition rule allowing state plan adjustments if state legislation is required, delaying full compliance until the legislative session begins after enactment.
Public Health Service Act: fortifier in private plans
Section 2730 adds a new Sec. 2730 to Subpart II of Title XXVII, requiring group health plans and health insurance issuers to cover human milk fortifier with no cost sharing. It creates alignment with the Medicaid/CHIP changes and specifies an effective date for plan years beginning on or after January 1, 2026.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Premature infants in NICUs and their families, who gain access to essential fortifier without out-of-pocket costs.
- Neonatal units and pediatric specialists, who face fewer billing barriers and clearer coverage pathways.
- State Medicaid agencies, which gain a standardized federal baseline that simplifies plan design and oversight.
- CHIP programs and participating states, which align with a uniform no-cost fortifier policy.
- Private health plans and issuers, which benefit from a clarified coverage mandate and reduced billing disputes.
- Donor milk fortifier manufacturers and suppliers, with increased demand for medically necessary products.
Who Bears the Cost
- State Medicaid programs may experience higher utilization-based costs due to broader fortifier coverage.
- CHIP programs could incur increased expenditures if enrollment grows in lines affecting fortifier use.
- Group and private insurers will incur costs from no-cost coverage, potentially affecting premium calculations.
- Hospitals and NICUs may bear upfront administrative costs to implement the coverage updates and ensure proper coding and reimbursement.
- Manufacturers and suppliers of fortifier could experience demand-driven pricing and production planning implications.
Key Issues
The Core Tension
Balancing universal no-cost fortifier coverage with the realities of state budgets, insurer administration, and provider variability in definitions and professional determinations creates a central dilemma: how to standardize access for a fragile population while avoiding unintended cost-shifts or implementation gaps across states and plans.
The bill creates a universal no-cost fortifier mandate across public and private coverage beginning 2026, but several practical tensions emerge. States face the challenge of funding expanded coverage while integrating new definitions and professional determinations into existing Medicaid and CHIP workflows.
Private plans must implement coordinated benefit designs across employer groups and carriers, which can take time and raise administrative costs. There is also a transition pathway for states needing legislative action before full CHIP implementation, which could create uneven rollout timelines across jurisdictions.
Finally, the policy hinges on a clear and enforceable definition of “donor milk fortifier” and the role of “specified professionals,” which may vary by state licensure and practice rules, potentially impacting who can determine medical necessity.
