Medicaid is a type of medical health insurance available for many people who are in specific income brackets which qualifies them to receive this government funded insurance. Whether or not someone qualifies for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify simply because they earn an acceptable income. For instance, men and women who have a lot of dependents may be eligible for Medicaid even though they make what might be considered a sensible income. Medicaid also can cover the expenses of rehab, when someone has been abusing drugs or alcohol and requires rehab. There are many drug rehabilitation centers which accept Medicaid, but various states have different rules for what sorts of treatment are covered. Some states only cover outpatient treatment services for example while other states cover more extensive rehabilitation such as a residential stay in long-term alcohol and drug rehab facility. If a person is involved in drug use and desires help, they're able to use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid plus don't have the cash or some other type of health care insurance to pay for rehabilitation, they could determine if they qualify for Medicaid and then sign up for an alcohol and drug treatment center which is approved within their state.
