Medicaid is a type of health insurance which is accessible to individuals in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other factors 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 or alcohol rehabilitation, and there are a lot of drug rehabilitation facilities throughout the country which are covered through Medicaid. Many drug and alcohol 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. Individuals who have Medicaid should look for which programs cover the greatest amount of treatment for the most amount of time to acquire the full rewards of a Medicaid rehab program.
