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 circumstances including 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 treatment, and there are many drug rehabilitation centers throughout the country which are covered through Medicaid. Many drug and alcohol rehabilitation facilities 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. Individuals who have Medicaid should look for which programs cover the greatest amount of treatment for the most amount of time to reap the full rewards of a Medicaid rehab program.
