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 circumstances 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 or alcohol rehab, and there are a lot of drug and alcohol rehabilitation centers throughout the country which are covered through Medicaid. Most drug treatment programs which are covered through Medicaid may only deliver a limited treatment curriculum and may only supply 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 acquire the full benefits of a Medicaid rehab program.
