Medicaid is a medical insurance available for those who are in certain income brackets which qualifies them to obtain this government funded insurance coverage. Whether somebody is qualified for Medicaid doesn't only determined by their earnings however, and people shouldn't presume they don't qualify simply because they earn an acceptable income. As an example, people who have quite a few dependents may be entitled to Medicaid even if they make what would be considered a fair income. Medicaid may also cover the costs of treatment, when someone has been abusing drugs or alcohol and needs rehab. There are several drug treatment programs which accept Medicaid, but various states have distinct guidelines for what kinds of rehabilitation are covered. Some states only cover outpatient rehabilitation services as an example while other states cover far more intensive treatment say for example a residential stay in long-term drug treatment center. If somebody is involved with substance abuse and wants help, they are able to use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid plus don't have the money or any other form of medical health insurance to cover treatment, they could see if they qualify for Medicaid and then enroll in a drug rehabilitation facility that is approved within their state.
