Medicaid is a kind of medical insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether somebody is qualified for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify just because they make an acceptable income. By way of example, individuals who have a lot of dependents may be entitled to Medicaid even if they earn what would be considered a sensible income. Medicaid also can cover the costs of treatment, when someone has been abusing drugs or alcohol and requires rehabilitation. There are lots of drug and alcohol treatment facilities which accept Medicaid, but different states have different rules for what kinds of treatment are covered. Some states only cover outpatient rehab services as an example while other states cover far more extensive rehab say for example a residential stay in long-term alcohol and drug rehabilitation facility. If anyone is involved with drug use and wants help, they can use their Medicaid insurance coverage to acquire this help. If they do not have Medicaid plus don't have the money or some other kind of health insurance to pay for rehab, they could check if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation facility that's approved in their state.
