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 factors such as whether or not the individual has dependents and if they receive any other financial assistance. Medicaid may even cover the costs associated with drug or alcohol treatment, and there are a lot of drug and alcohol treatment facilities throughout the country which are covered through Medicaid. Many drug rehabilitation programs which are covered through Medicaid may only deliver a limited treatment curriculum and may only supply such treatment on a short term basis, typically 30 days or less. People 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.
