Medicaid is a form of health care insurance available for many people who are in certain income brackets which qualifies them to acquire this government funded insurance coverage. Whether someone qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify just because they make a fair income. As an example, people who have a lot of dependents may be eligible for Medicaid even if they make an amount be described as a reasonable income. Medicaid can also cover the expenses of rehabilitation, when someone has been abusing drugs or alcohol and needs rehabilitation. There are many drug and alcohol rehabilitation programs which accept Medicaid, but different states have different guidelines for what forms of treatment are covered. Certain states only cover outpatient treatment services for example while other states cover far more extensive rehabilitation like a residential stay in long-term alcohol and drug rehabilitation program. If somebody is involved in drug abuse and needs help, they are able to use their Medicaid health coverage to acquire this help. If they do not have Medicaid and also don't have the cash or some other kind of health insurance to pay for rehabilitation, they could determine if they qualify for Medicaid and then enroll in an alcohol and drug treatment facility which is approved in their state.
