Medicaid is a kind of health care insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance. Whether an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify because they earn a fair income. As an example, people who have a lot of dependents may qualify for Medicaid even if they make what might be described as a fair income. Medicaid could also cover the costs of rehabilitation, if a person has been abusing drugs or alcohol and needs treatment. There are several drug and alcohol rehab programs which accept Medicaid, but various states have distinct rules for what forms of rehabilitation are covered. Some states only cover outpatient treatment services for example while other states cover far more intensive treatment like a residential stay in long-term drug rehab program. If a person is involved with drug abuse and needs help, they are able to use their Medicaid insurance coverage to get this help. If they don't have Medicaid and in addition don't have the money or some other form of medical insurance to cover rehab, they can find out if they qualify for Medicaid and then enroll in an alcohol and drug treatment center that is approved in their state.
