Eligibility for Assistance and Projected Changes in Coverage Under the ACA

Variation Across States

Update: 27.7 million previously uninsured people are eligible for assistance under the Affordable Care Act

This updated report finds that under current legislation, just over half (56 percent) of the uninsured became eligible for financial assistance with health insurance coverage through Medicaid, CHIP or subsidized private coverage through the new marketplaces.

Key Findings

  • In states that have expanded Medicaid eligibility under the ACA, 68 percent of the uninsured became eligible for assistance, compared with only 44 percent in states that have not expanded Medicaid.

  • If nonexpansion states were to expand Medicaid eligibility, 71 percent of their uninsured would be eligible for assistance.

  • Among states expanding Medicaid, the ACA is projected to reduce the number of uninsured people by 56 percent, compared with a 34 percent reduction in the uninsured among states not expanding Medicaid.

  • If the states that have not expanded eligibility were to do so, the number of uninsured in those states would decrease by 59 percent.
