Medicaid is a medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government funded insurance. 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 make an acceptable income. For example, men and women who have quite a few dependents may be eligible for Medicaid even when they earn what can be considered a fair income. Medicaid can also cover the expense of rehabilitation, when someone has been abusing alcohol or drugs and needs rehab. There are several alcohol and drug rehab centers which accept Medicaid, but different states have different guidelines for what forms of treatment are covered. Some states only cover outpatient rehab services for instance while other states cover far more intensive treatment like a residential stay in long-term drug and alcohol rehab facility. If someone is involved with drug use and wants help, they are able to use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid and in addition don't have the money or another kind of medical insurance to pay for rehabilitation, they could check if they are eligible for a Medicaid and then sign up for a drug and alcohol treatment center that's approved within their state.
