Medicaid is a kind of medical health insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they make a fair income. As an example, people who have a lot of dependents may qualify for Medicaid even though they earn what can be considered a sensible income. Medicaid also can cover the costs of rehab, when someone has been abusing drugs or alcohol and needs treatment. There are several drug rehabilitation facilities which accept Medicaid, but various states have different rules for what kinds of treatment are covered. Some states only include outpatient treatment services for example while other states cover far more extensive treatment say for example a residential stay in long-term alcohol and drug treatment center. If anyone is involved in drug use and needs help, they are able to use their Medicaid insurance coverage to obtain this treatment. If they do not have Medicaid and in addition don't have the funds or another kind of medical insurance to pay for rehab, they can see if they are eligible for a Medicaid and then sign up for a drug and alcohol treatment facility that's approved within their state.
