Medicaid is a type of health insurance which is made available to individuals in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other factors including whether or not the individual has dependents and if they receive any other financial assistance. Medicaid may even cover the costs associated with drug treatment, and there are many drug treatment programs throughout the country which are covered through Medicaid. Most drug and alcohol rehabilitation facilities which are covered through Medicaid may only provide a limited treatment curriculum and may only deliver such treatment on a short term basis, usually 30 days or less. People who have Medicaid should look for which programs cover the greatest amount of treatment for the most amount of time to acquire the full rewards of a Medicaid rehab program.
