Medicaid is a form of medical health insurance available for those who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether or not a person is qualified for Medicaid doesn't only determined by income however, and individuals shouldn't assume they don't qualify because they earn a good income. For example, people who have a lot of dependents may be entitled to Medicaid even if they make what would be considered a fair income. Medicaid also can cover the costs of treatment, when someone has been abusing alcohol or drugs and needs treatment. There are several drug and alcohol rehab facilities which accept Medicaid, but different states have different guidelines for what kinds of rehabilitation are covered. Some states only include outpatient rehab services by way of example while other states cover more extensive rehabilitation like a residential stay in long-term drug treatment facility. If a person is involved in drug use and desires help, they can use their Medicaid insurance coverage to get this help. If they do not have Medicaid and in addition don't have the funds or any other form of health care insurance to pay for rehabilitation, they can determine if they qualify for Medicaid and then enroll in a drug treatment program that is approved within their state.
