Medicaid is a type of health insurance which is offered to people in certain low-income tax brackets. Eligibility for Medicaid is dependent on income and other circumstances including whether or not the individual has dependents and if they receive any other financial assistance. Medicaid may even cover the costs associated with drug or alcohol rehabilitation, and there are many drug treatment programs throughout the country which are covered through Medicaid. Most drug rehabilitation facilities 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. Individuals who have Medicaid should explore which programs cover the greatest amount of treatment for the most amount of time to acquire the full benefits of a Medicaid rehab program.
