Medicaid is a kind of medical insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance. Whether somebody is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify simply because they make a good income. For example, people who have quite a few dependents may be eligible for Medicaid even when they make what might certainly be a fair income. Medicaid may also cover the costs of rehab, if someone has been abusing drugs or alcohol and requires treatment. There are many drug and alcohol rehab centers which accept Medicaid, but various states have distinct rules for what forms of rehabilitation are covered. Some states only cover outpatient rehab services by way of example while other states cover far more intensive rehabilitation such as a residential stay in long-term alcohol and drug treatment facility. If a person is involved in substance abuse and needs help, they can use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid and in addition don't have the funds or another kind of medical insurance to pay for rehab, they could find out if they are eligible for a Medicaid and then enroll in a drug treatment center which is approved inside their state.
