Medicaid is a type of health insurance which is accessible to individuals in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other circumstances including whether or not the person has dependents and if they receive any other financial assistance. Medicaid may even cover the costs associated with drug rehab, and there are a lot of drug rehabilitation facilities throughout the country which are covered through Medicaid. Many drug and alcohol rehabilitation programs which are covered through Medicaid may only deliver 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 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.
