Medicaid is a medical health insurance available for those who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not someone is qualified for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify simply because they earn a reasonable income. By way of example, people who have many dependents may be eligible for Medicaid even though they earn an amount be considered a sensible income. Medicaid also can cover the expenses of rehab, when someone has been abusing drugs or alcohol and requires treatment. There are lots of drug rehabilitation facilities which accept Medicaid, but various states have distinct rules for what kinds of rehabilitation are covered. Some states only cover outpatient treatment services for example while other states cover far more extensive treatment such as a residential stay in long-term drug and alcohol treatment center. If a person is involved with substance abuse and needs help, they could use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid and in addition don't have the cash or another kind of medical health insurance to pay for rehabilitation, they can check if they qualify for Medicaid and then enroll in a drug and alcohol treatment program which is approved within their state.
