Medicaid is a type of health insurance which is made available to individuals 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 possibly even cover the costs associated with drug rehabilitation, and there are a lot of drug and alcohol rehabilitation facilities throughout the country which are covered through Medicaid. Many drug rehabilitation 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 explore which programs cover the greatest amount of treatment for the most amount of time to reap the full benefits of such a program.
