Medicaid is a kind of medical health insurance available for many people who are in certain income brackets which qualifies them to acquire this government funded insurance coverage. Whether someone is qualified for Medicaid doesn't only determined by income however, and people shouldn't presume they don't qualify simply because they make a good income. As an example, people who have quite a few dependents may be entitled to Medicaid even when they make what can be described as a fair income. Medicaid may also cover the costs of treatment, if a person has been abusing drugs or alcohol and requires treatment. There are numerous alcohol and drug rehab programs which accept Medicaid, but various states have different rules for what types of treatment are covered. Some states only cover outpatient rehab services as an example while other states cover far more extensive treatment such as a residential stay in long-term alcohol and drug rehabilitation program. If somebody is involved with drug use and wants help, they can use their Medicaid health coverage to get this help. If they do not have Medicaid plus don't have enough cash or any other type of medical health insurance to cover treatment, they can check if they are eligible for a Medicaid and then sign up for a drug rehab center which is approved within their state.
