Medicaid is a type of health insurance which is offered to individuals in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other circumstances such as 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 rehabilitation, and there are many drug rehab facilities throughout the country which are covered through Medicaid. Most drug and alcohol treatment facilities which are covered through Medicaid may only provide a limited treatment curriculum and may only deliver 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.
