Medicaid is a health care insurance available for many people who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether somebody is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify simply because they make a reasonable income. As an example, people who have quite a few dependents may be eligible for Medicaid even though they earn what might certainly be a reasonable income. Medicaid could also cover the costs of rehabilitation, if someone has been abusing alcohol or drugs and needs treatment. There are many drug and alcohol rehabilitation facilities which accept Medicaid, but various states have different guidelines for what kinds of rehab are covered. Some states only cover outpatient treatment services for instance while other states cover far more extensive rehabilitation like a residential stay in long-term drug and alcohol rehabilitation center. If someone is involved with drug use and wants help, they can use their Medicaid health coverage to obtain this help. If they don't have Medicaid and in addition don't have enough cash or another kind of medical insurance to pay for rehabilitation, they could check if they qualify for Medicaid and then sign up for an alcohol and drug rehab facility which is approved within their state.
