Medicaid is a form of health care insurance available for those who are in specific income brackets which qualifies them to receive this government funded insurance coverage. Whether a person qualifies for Medicaid doesn't only determined by their earnings however, and people shouldn't presume they don't qualify just because they make an acceptable income. For example, men and women who have quite a few dependents may be entitled to Medicaid even when they earn what might be considered a reasonable income. Medicaid may also cover the expenses of treatment, if a person has been abusing drugs or alcohol and requires rehab. There are lots of drug and alcohol rehab centers which accept Medicaid, but different states have distinct guidelines for what sorts of rehabilitation are covered. Certain states only cover outpatient treatment services for instance while other states cover far more extensive rehabilitation such as a residential stay in long-term drug and alcohol treatment center. If a person is involved in drug use and desires help, they are able to use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid and in addition don't have the money or some other form of medical health insurance to pay for rehab, they could determine if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation program that is approved inside their state.
