Medicaid is a kind of health insurance available for many people who are in specific income brackets which qualifies them to receive this government funded insurance. Whether someone is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they make a fair income. For example, individuals who have many dependents may be eligible for Medicaid even if they make what might certainly be a sensible income. Medicaid may also cover the costs of rehabilitation, if someone has been abusing drugs or alcohol and requires rehab. There are lots of drug and alcohol treatment facilities which accept Medicaid, but various states have different guidelines for what forms of rehabilitation are covered. Some states only include outpatient rehab services for instance while other states cover far more extensive treatment such as a residential stay in long-term drug and alcohol treatment program. If anyone is involved in drug abuse and needs help, they can use their Medicaid health coverage to obtain this treatment. If they do not have Medicaid and also don't have the money or some other form of health insurance to cover rehab, they can check if they qualify for Medicaid and then enroll in a drug and alcohol treatment center that is approved inside their state.
