Medicaid is a type of medical health insurance available for individuals who are in specific income brackets which qualifies them to obtain this government funded insurance. Whether or not somebody qualifies for Medicaid doesn't only depend upon their earnings however, and individuals shouldn't assume they don't qualify simply because they earn a reasonable income. By way of example, individuals who have quite a few dependents may be entitled to Medicaid even if they earn what would be described as a reasonable income. Medicaid may also cover the expense of rehab, if someone has been abusing drugs or alcohol and requires rehab. There are many drug rehab centers which accept Medicaid, but different states have different guidelines for what types of treatment are covered. Some states only include outpatient treatment services for example while other states cover more extensive treatment say for example a residential stay in long-term drug treatment center. If a person is involved in substance abuse and wants help, they can use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid plus don't have the cash or another kind of medical health insurance to cover treatment, they could check if they qualify for Medicaid and then enroll in an alcohol and drug treatment program that is approved within their state.
