Medicaid is a type of health insurance which is offered to people in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other circumstances including whether or not the individual has dependents and if they receive any other financial assistance. Medicaid may possibly even cover the costs associated with drug or alcohol rehab, and there are a lot of drug rehab facilities throughout the country which are covered through Medicaid. Most drug and alcohol treatment programs which are covered through Medicaid may only provide a limited treatment curriculum and may only supply such treatment on a short term basis, usually 30 days or less. Individuals who have Medicaid should explore which programs cover the greatest amount of treatment for the most amount of time to acquire the full rewards of a Medicaid rehab program.
