Dual eligibles, who qualify for both Medicare and Medicaid, make up different percentages of total Medicare populations across states, ranging from 11% in Montana to 37% in Maine. Individuals can qualify for Medicaid through various pathways including Supplemental Security Income (SSI), medically needy coverage, and Medicare Savings Programs. States with higher percentages of dual eligibles tend to have higher poverty rates and Medicaid programs that cover individuals with higher incomes. The Affordable Care Act aims to improve care coordination and lower costs for this vulnerable population through the Federal Coordinated Health Care Office.
