Medicaid is a type of health insurance which is offered to individuals in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other factors including whether or not the person has dependents and if they receive any other financial assistance. Medicaid may possibly even cover the costs associated with drug rehabilitation, and there are a lot of drug rehabilitation facilities throughout the country which are covered through Medicaid. Most drug 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, typically 30 days or less. Individuals who have Medicaid should research which programs cover the greatest amount of treatment for the most amount of time to acquire the full rewards of a Medicaid rehab program.
