Medicaid is a form of health insurance available for those who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether or not somebody qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't presume they don't qualify just because they earn a good income. For example, men and women who have a lot of dependents may be entitled to Medicaid even if they make what might certainly be a sensible income. Medicaid may also cover the expense of rehabilitation, when someone has been abusing drugs or alcohol and requires rehab. There are many alcohol and drug treatment facilities which accept Medicaid, but different states have distinct rules for what sorts of rehabilitation are covered. Certain states only include outpatient rehab services for example while other states cover far more extensive rehab say for example a residential stay in long-term drug rehabilitation program. If someone is involved in substance abuse and wants help, they can use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid plus don't have the money or another form of health care insurance to cover treatment, they can see if they are eligible for a Medicaid and then sign up for a drug treatment center that is approved inside their state.
