Medicaid is a form of health insurance available for many people who are in certain income brackets which qualifies them to receive this government funded insurance. Whether someone qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify just because they make a fair income. For example, men and women who have a lot of dependents may be eligible for Medicaid regardless of whether they earn what might be described as a fair income. Medicaid can also cover the expense of rehab, if someone has been abusing drugs or alcohol and requires rehab. There are many alcohol and drug rehabilitation programs which accept Medicaid, but various states have distinct guidelines for what types of rehabilitation are covered. Certain states only include outpatient rehabilitation services for instance while other states cover far more intensive treatment such as a residential stay in long-term drug and alcohol rehab facility. If somebody is involved with drug abuse and desires help, they're able to use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid and in addition don't have the money or some other type of medical health insurance to cover rehabilitation, they could check if they are eligible for a Medicaid and then sign up for a drug treatment facility that is approved within their state.
