What is Medicaid?
Every state runs a Medicaid program although it may be called something else. For example, California has Medi-Cal; Maine has MaineCare. This program provides health insurance for those who can least afford it. The coverage is very comprehensive - including doctors visits, hospital care, dental care, prescriptions and mental health care.
How to I apply?
Each state has its own income and asset guidelines. Some states include more categories of people (for example, non-disabled adults with no children) and people with somewhat higher incomes. Most states also have related programs, to provide some help to those who do not qualify for full Medicaid benefits. For example, most states provide help with prescription drugs for adults with higher incomes.
Also, many more children now qualify due to federal CHIP [formerly SCHIP] funding. Again, each state runs its own program and sets many of the rules. Most states provide CHIP coverage for children in families at or above 200% of the federal poverty level [FLP]. But some states cover children in families up to as high as 350% FLP. See chart below.
All of the states' Medicaid programs use a complex system of eligibility rules, with different income and asset tests for each category of people served. Ask your local Social Services office for details, or see if their website posts the rules.
