Medicaid is a type of health insurance which is made available to people in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other circumstances such as whether or not the person has dependents and if they receive any other assistance. Medicaid may even cover the costs associated with drug or alcohol treatment, and there are many 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, typically 30 days or less. People who have Medicaid should look for which programs cover the greatest amount of treatment for the most amount of time to acquire the full benefits of a Medicaid rehab program.
