Medicaid is a form of health insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether an individual qualifies for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify just because they make a good income. For example, individuals who have quite a few dependents may be eligible for Medicaid even when they make what can be described as a sensible income. Medicaid also can cover the costs of rehab, when someone has been abusing alcohol or drugs and needs treatment. There are many alcohol and drug rehab programs which accept Medicaid, but different states have distinct guidelines for what forms of rehab are covered. Some states only include outpatient treatment services for example while other states cover more intensive rehab such as a residential stay in long-term drug treatment program. If somebody is involved with drug abuse and needs help, they could use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid and in addition don't have the money or any other type of medical insurance to pay for rehabilitation, they can check if they qualify for Medicaid and then enroll in an alcohol and drug rehabilitation facility which is approved in their state.
