Medicaid is a type of health insurance which is made available to people in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other circumstances such as whether or not the person has dependents and if they receive any other assistance. Medicaid may possibly even cover the costs associated with drug rehab, and there are many drug and alcohol treatment programs 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 provide 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 benefits of a Medicaid rehab program.
