Medicaid is a type of health insurance which is accessible to individuals in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other factors including whether or not the person has dependents and if they receive any other assistance. Medicaid may even cover the costs associated with drug treatment, and there are many drug and alcohol rehabilitation facilities throughout the country which are covered through Medicaid. Most drug rehab programs which are covered through Medicaid may only deliver a limited treatment curriculum and may only supply such treatment on a short term basis, usually 30 days or less. People who have Medicaid should research which programs cover the greatest amount of treatment for the most amount of time to acquire the full benefits of such a program.
