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 circumstances including whether or not the individual has dependents and if they receive any other financial assistance. Medicaid may even cover the costs associated with drug rehabilitation, and there are a lot of drug and alcohol treatment centers throughout the country which are covered through Medicaid. Most drug and alcohol rehab facilities which are covered through Medicaid may only deliver a limited treatment curriculum and may only supply such treatment on a short term basis, usually 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.
