Medicaid is a type of health care insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether someone is qualified for Medicaid doesn't only determined by income however, and individuals shouldn't presume they don't qualify simply because they make a good income. For example, individuals who have quite a few dependents may be entitled to Medicaid even when they earn what might be considered a reasonable income. Medicaid could also cover the price of treatment, if someone has been abusing drugs or alcohol and requires treatment. There are numerous drug treatment centers which accept Medicaid, but different states have different rules for what kinds of treatment are covered. Some states only include outpatient treatment services for instance while other states cover more extensive rehab like a residential stay in long-term drug treatment program. If someone is involved with drug abuse and wants help, they could use their Medicaid insurance coverage to get this treatment. If they do not have Medicaid plus don't have the cash or some other type of health insurance to pay for rehab, they can check if they are eligible for a Medicaid and then sign up for an alcohol and drug treatment center that's approved in their state.
