Medicaid is a type of health insurance which is made available to individuals 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 assistance. Medicaid may even cover the costs associated with drug or alcohol treatment, and there are a lot of 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 deliver such treatment on a short term basis, typically 30 days or less. Individuals who have Medicaid should explore which programs cover the greatest amount of treatment for the most amount of time to reap the full rewards of a Medicaid rehab program.
