Medicaid is a kind of medical health insurance available for those who are in certain income brackets which qualifies them to obtain this government funded insurance coverage. Whether a person qualifies for Medicaid doesn't only determined by their earnings however, and individuals shouldn't presume they don't qualify just because they make a reasonable income. For example, individuals who have quite a few dependents may be entitled to Medicaid even when they earn what might be described as a fair income. Medicaid can also cover the expenses of treatment, if a person has been abusing drugs or alcohol and requires rehabilitation. There are several drug and alcohol rehab programs which accept Medicaid, but various states have different guidelines for what types of rehab are covered. Certain states only include outpatient rehab services for example while other states cover more extensive treatment such as a residential stay in long-term alcohol and drug rehab facility. If somebody is involved with substance abuse and needs help, they are able to use their Medicaid insurance coverage to get this treatment. If they do not have Medicaid plus don't have the funds or some other kind of medical insurance to cover rehab, they could find out if they qualify for Medicaid and then enroll in an alcohol and drug rehab center that is approved in their state.
