Medicaid is a kind of medical insurance available for those who are in certain income brackets which qualifies them to receive this government provided insurance. Whether someone qualifies for Medicaid doesn't only determined by income however, and individuals shouldn't presume they don't qualify simply because they earn a good income. For example, men and women who have many dependents may be eligible for Medicaid even though they earn an amount be considered a fair income. Medicaid could also cover the expenses of rehabilitation, if someone has been abusing drugs or alcohol and needs treatment. There are many drug rehab programs which accept Medicaid, but different states have different rules for what sorts of rehab are covered. Some states only cover outpatient treatment services for example while other states cover far more extensive rehabilitation like a residential stay in long-term drug treatment facility. If a person is involved with drug use and wants help, they could use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid and in addition don't have enough cash or another form of health insurance to pay for rehab, they can find out if they are eligible for a Medicaid and then sign up for a drug treatment center which is approved within their state.
