Medicaid is a form of health insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance coverage. Whether or not someone qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify because they make a good income. By way of example, people who have quite a few dependents may qualify for Medicaid even if they make an amount be considered a fair income. Medicaid may also cover the costs of rehabilitation, if a person has been abusing drugs or alcohol and requires rehab. There are several drug and alcohol rehabilitation programs which accept Medicaid, but different states have different guidelines for what sorts of rehabilitation are covered. Some states only include outpatient rehabilitation services for example while other states cover far more extensive rehabilitation say for example a residential stay in long-term drug and alcohol treatment center. If anyone is involved with drug use and desires help, they're able to use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and also don't have the cash or another form of health care insurance to pay for treatment, they can check if they qualify for Medicaid and then enroll in a drug rehab center that is approved inside their state.
