Low-income adults may obtain free health insurance through Medicaid or may receive subsidies to cover the cost of purchasing health insurance through state health care marketplaces, according to the Kaiser Family Foundation and CBS News. Social Security Disability Insurance recipients also may be eligible for Medicaid, according to HealthCare.gov.
In states that have expanded Medicaid coverage, a single adult who earns less than $16,000 a year may qualify for Medicaid as of 2016, notes the Kaiser Family Foundation. SSDI recipients are eligible for Medicaid automatically in many states or may have guaranteed eligibility after applying for it, advises HealthCare.gov. Adults under the age of 26 may have the option to remain covered under a parent's health care plan.
