Medicaid is a type of health insurance which is made available to people in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other circumstances such as whether or not the person has dependents and if they receive any other assistance. Medicaid may possibly even cover the costs associated with drug or alcohol rehabilitation, and there are a lot of drug rehabilitation centers throughout the country which are covered through Medicaid. Many drug treatment facilities 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. Individuals who have Medicaid should research which programs cover the greatest amount of treatment for the most amount of time to acquire the full rewards of a Medicaid rehab program.
