Medicaid is a kind of medical insurance available for individuals who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether someone qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify simply because they earn an acceptable income. For instance, men and women who have a lot of dependents may be entitled to Medicaid even though they make what would be described as a fair income. Medicaid can also cover the expense of rehab, when someone has been abusing drugs or alcohol and requires rehabilitation. There are lots of drug treatment facilities which accept Medicaid, but various states have different guidelines for what kinds of rehabilitation are covered. Some states only include outpatient rehabilitation services for instance while other states cover more intensive treatment like a residential stay in long-term drug and alcohol rehab program. If someone is involved with drug use and desires help, they can use their Medicaid insurance coverage to get this help. If they do not have Medicaid and in addition don't have enough cash or another kind of health insurance to cover rehabilitation, they could check if they qualify for Medicaid and then sign up for a drug rehabilitation center which is approved within their state.
