Medicaid is a type of health insurance which is accessible to people in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other factors such as whether or not the person has dependents and if they receive any other financial assistance. Medicaid may even cover the costs associated with drug or alcohol rehab, and there are many drug rehabilitation programs throughout the country which are covered through Medicaid. Most drug and alcohol 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.
