Medicaid is a type of medical insurance available for those who are in certain income brackets which qualifies them to receive this government funded insurance coverage. Whether somebody is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify just because they make an acceptable income. For example, men and women who have quite a few dependents may be entitled to Medicaid even if they earn what might be described as a reasonable income. Medicaid also can cover the expense of rehabilitation, if someone has been abusing drugs or alcohol and requires rehabilitation. There are many drug rehab facilities which accept Medicaid, but various states have distinct rules for what types of treatment are covered. Some states only cover outpatient treatment services for instance while other states cover far more extensive treatment such as a residential stay in long-term drug and alcohol rehab facility. If a person is involved in drug abuse and needs help, they could use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid and in addition don't have enough cash or some other form of medical health insurance to pay for treatment, they can check if they are eligible for a Medicaid and then enroll in an alcohol and drug treatment facility that's approved within their state.
