Medicaid is a type of health insurance which is accessible to people in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other factors including whether or not the individual has dependents and if they receive any other assistance. Medicaid may even cover the costs associated with drug treatment, and there are many drug rehab centers throughout the country which are covered through Medicaid. Many drug and alcohol treatment facilities which are covered through Medicaid may only provide 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 reap the full rewards of a Medicaid rehab program.
