Medicaid is a type of health insurance which is accessible to people in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other factors including whether or not the individual has dependents and if they receive any other assistance. Medicaid may possibly even cover the costs associated with drug rehab, and there are many drug treatment facilities throughout the country which are covered through Medicaid. Many drug and alcohol treatment programs which are covered through Medicaid may only provide a limited treatment curriculum and may only provide such treatment on a short term basis, typically 30 days or less. People who have Medicaid should research which programs cover the greatest amount of treatment for the most amount of time to reap the full benefits of a Medicaid rehab program.
