Medicaid is a form of medical insurance available for those who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether or not an individual is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify just because they earn a good income. For instance, individuals who have quite a few dependents may be entitled to Medicaid even though they earn what might be considered a fair income. Medicaid can also cover the expenses of treatment, if someone has been abusing drugs or alcohol and needs rehab. There are several drug rehab facilities which accept Medicaid, but various states have different guidelines for what sorts of rehabilitation are covered. Some states only include outpatient treatment services as an example while other states cover far more extensive rehab such as a residential stay in long-term drug treatment facility. If a person is involved in substance abuse and desires help, they are able to use their Medicaid health coverage to get this treatment. If they don't have Medicaid plus don't have enough cash or any other kind of health insurance to pay for rehab, they can check if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation program which is approved within their state.
