Medicaid is a type of health insurance which is accessible to people in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other circumstances such as 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 rehab, and there are many drug rehabilitation programs throughout the country which are covered through Medicaid. Most drug and alcohol rehabilitation facilities which are covered through Medicaid may only deliver a limited treatment curriculum and may only deliver such treatment on a short term basis, usually 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.
