Medicaid is a type of health insurance which is made available to people in certain low-income tax brackets. Eligibility for Medicaid depends greatly on income and other factors such as whether or not the individual has dependents and if they receive any other assistance. Medicaid may possibly even cover the costs associated with drug rehabilitation, and there are many drug treatment programs throughout the country which are covered through Medicaid. Most drug and alcohol rehabilitation 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 look for which programs cover the greatest amount of treatment for the most amount of time to acquire the full rewards of a Medicaid rehab program.
