Homeless Veterans Eligible for Medicaid Under the Affordable Care Act.

Objective: Among homeless veterans and those at risk of homelessness currently enrolled in Veterans Affairs (VA) health care, this study examined the proportion likely to become eligible for Medicaid in 2014 and their health needs.
Methods: A total of 114,497 homeless and at-risk veterans were categorized into three groups: currently covered by Medicaid, likely to become eligible for Medicaid, and not likely.
Results: Seventy-eight percent of the sample was determined to be likely to become eligible for Medicaid in states that expand Medicaid. Compared with veterans not likely to become eligible for Medicaid, those likely to become eligible were less likely to have general medical and psychiatric conditions and to have a VA service-connected disability but more likely to have substance use disorders.
Conclusions: Programs serving homeless and at-risk veterans should anticipate the potential interplay between VA health care and the expansion of Medicaid in states that implement the expansion.
