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 individual has dependents and if they receive any other assistance. Medicaid may possibly even cover the costs associated with drug treatment, and there are a lot of drug rehab centers 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 provide such treatment on a short term basis, usually 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 acquire the full benefits of a Medicaid rehab program.
