Medicaid is a health insurance available for individuals who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether an individual is qualified for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify because they earn an acceptable income. For instance, individuals who have quite a few dependents may be entitled to Medicaid even when they make what can be described as a sensible income. Medicaid can also cover the expense of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are several drug rehab facilities which accept Medicaid, but various states have different guidelines for what kinds of rehabilitation are covered. Some states only include outpatient rehabilitation services as an example while other states cover far more extensive rehab like a residential stay in long-term drug and alcohol rehab program. If a person is involved in substance abuse and desires help, they can use their Medicaid insurance coverage to obtain this help. If they do not have Medicaid and in addition don't have the cash or some other type of medical insurance to pay for treatment, they can find out if they qualify for Medicaid and then enroll in an alcohol and drug treatment center that's approved in their state.
