Medicaid is a type of health insurance which is accessible to people in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other factors including whether or not the person has dependents and if they receive any other financial assistance. Medicaid may even cover the costs associated with drug rehab, and there are many drug and alcohol rehab facilities throughout the country which are covered through Medicaid. Most drug and alcohol rehab facilities which are covered through Medicaid may only deliver a limited treatment curriculum and may only deliver such treatment on a short term basis, usually 30 days or less. Individuals 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 a Medicaid rehab program.
