Between 2008 and 2015, children’s Medicaid/CHIP enrollment increased by almost a third, the children’s uninsured rate fell by nearly half, and adult Medicaid enrollment expanded significantly. Over that period, financial access, provider access, and receipt of routine care improved among children covered by Medicaid/CHIP. Congress is now considering cuts to federal funding for Medicaid and CHIP that could jeopardize these gains in coverage and access for children. If the cuts are approved, fewer children may be covered by Medicaid/CHIP, and those who are covered may see their care deteriorate.
