The principle that children ought to have access to the health care they need enjoys broad support. Consistent with this principle, Congress has long required states, as a condition of receiving federal Medicaid funding, to provide children with comprehensive coverage under their state Medicaid programs. This broad coverage standard is particularly important for Medicaid-eligible children whose health care needs are often greater than the norm and whose families' limited incomes make it difficult for them to afford care that Medicaid does not cover.
