Medicaid is a type of health insurance which is accessible to people in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other factors such as 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 rehab, and there are a lot of drug rehab facilities throughout the country which are covered through Medicaid. Most drug rehab 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. 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.
