A New Jersey law went into effect on Jan. 1, 2019, requiring all health insurers in the state to cover donated human breast milk for infants under certain circumstances. Insurers must cover the costs if the infant is aged younger than 6 months, the milk comes from a milk bank that meets the quality guidelines of the Human Milk Banking Association of North America or is licensed by the New Jersey Department of Health, and it is prescribed to the infant by a physician. Similar laws are in place in California, New York, Missouri, Kansas, Texas and Washington, D.C.
