Medicaid is a medical insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not someone qualifies for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify simply because they earn a good income. For instance, men and women who have many dependents may be entitled to Medicaid even if they earn what might be considered a reasonable income. Medicaid may also cover the expenses of treatment, if someone has been abusing drugs or alcohol and requires rehab. There are numerous drug treatment facilities which accept Medicaid, but various states have distinct guidelines for what kinds of treatment are covered. Some states only cover outpatient rehabilitation services for example while other states cover far more extensive rehabilitation say for example a residential stay in long-term alcohol and drug rehabilitation facility. If somebody is involved in drug use and wants help, they're able to use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid plus don't have the money or another form of health insurance to pay for rehabilitation, they can find out if they qualify for Medicaid and then sign up for an alcohol and drug treatment facility which is approved inside their state.
