Medicaid—a federal/state partnership with shared authority and financing—is a health insurance program for low-income individuals, children, their parents, the elderly and people with disabilities.
Medicaid pays for health care for more than 74.5 million people nationally. Although participation is optional, all 50 states participate in the Medicaid program.
However, eligibility for Medicaid benefits varies widely among the states - all states must meet federal minimum requirements, but they have options for expanding Medicaid beyond the minimum federal guidelines, the details are outlined here.
States continue to consider the costs and benefits of expansion, and whether or not to pursue expansion through innovative Section 1115 waivers.
