Medicaid is a health insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify because they earn an acceptable income. For example, people who have quite a few dependents may be eligible for Medicaid even when they make an amount be described as a sensible income. Medicaid could also cover the expenses of treatment, when someone has been abusing drugs or alcohol and needs rehab. There are lots of drug rehabilitation centers which accept Medicaid, but various states have distinct guidelines for what types of rehab are covered. Some states only include outpatient rehab services for example while other states cover far more intensive treatment say for example a residential stay in long-term alcohol and drug treatment center. If someone is involved with drug abuse and desires help, they could use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and also don't have the money or any other form of medical health insurance to pay for treatment, they can determine if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation center that is approved within their state.
