Medicaid is a form of medical insurance available for individuals who are in certain income brackets which qualifies them to acquire this government funded insurance coverage. Whether or not somebody is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify just because they make an acceptable income. For example, individuals who have a lot of dependents may be entitled to Medicaid regardless of whether they make what might be considered a fair income. Medicaid also can cover the costs of rehab, if someone has been abusing alcohol or drugs and needs treatment. There are several drug and alcohol rehabilitation programs which accept Medicaid, but various states have different guidelines for what types of rehabilitation are covered. Certain states only include outpatient treatment services for instance while other states cover more extensive rehabilitation like a residential stay in long-term drug treatment facility. If a person is involved in drug abuse and wants help, they could use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid and in addition don't have the cash or another type of health insurance to cover rehab, they could check if they are eligible for a Medicaid and then enroll in an alcohol and drug rehab facility which is approved within their state.
