Medicaid is a form of medical insurance available for individuals who are in specific income brackets which qualifies them to obtain this government funded insurance coverage. Whether an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify just because they make a good income. For instance, people who have quite a few dependents may be eligible for Medicaid regardless of whether they make what can be considered a reasonable income. Medicaid also can cover the expenses of rehab, when someone has been abusing drugs or alcohol and requires rehabilitation. There are numerous drug rehab programs which accept Medicaid, but different states have different rules for what forms of rehab are covered. Certain states only include outpatient rehabilitation services for instance while other states cover far more intensive rehab such as a residential stay in long-term alcohol and drug rehabilitation facility. If somebody is involved with drug use and wants help, they can use their Medicaid insurance coverage to acquire this help. If they do not have Medicaid and in addition don't have the funds or any other form of medical health insurance to cover treatment, they could check if they qualify for Medicaid and then enroll in an alcohol and drug rehabilitation center that is approved within their state.
