Medicaid is a form of medical health insurance available for individuals who are in specific income brackets which qualifies them to receive this government provided insurance coverage. Whether someone qualifies for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify simply because they earn an acceptable income. As an example, individuals who have a lot of dependents may qualify for Medicaid even though they make what might be described as a fair income. Medicaid may also cover the expenses of treatment, if someone has been abusing drugs or alcohol and needs rehab. There are lots of drug and alcohol rehabilitation centers which accept Medicaid, but different states have distinct guidelines for what sorts of rehabilitation are covered. Some states only cover outpatient rehab services for instance while other states cover more extensive rehabilitation like a residential stay in long-term drug and alcohol rehab facility. If anyone is involved in drug abuse and desires help, they are able to use their Medicaid health coverage to obtain this help. If they do not have Medicaid plus don't have enough cash or another form of medical insurance to pay for rehabilitation, they can see if they are eligible for a Medicaid and then enroll in a drug rehabilitation facility which is approved within their state.
