Medicaid is a form of medical insurance available for many people who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether or not someone qualifies for Medicaid doesn't only depend upon income however, and people shouldn't presume they don't qualify just because they earn an acceptable income. As an example, people who have a lot of dependents may qualify for Medicaid even when they earn what might be considered a sensible income. Medicaid also can cover the costs of rehabilitation, if someone has been abusing alcohol or drugs and requires rehab. There are several alcohol and drug rehab facilities which accept Medicaid, but different states have different guidelines for what forms of treatment are covered. Some states only include outpatient treatment services by way of example while other states cover more intensive rehabilitation say for example a residential stay in long-term alcohol and drug rehab program. If somebody is involved with drug use and needs help, they are able to use their Medicaid health coverage to get this help. If they don't have Medicaid and also don't have the cash or some other form of health care insurance to cover rehab, they can see if they are eligible for a Medicaid and then enroll in a drug and alcohol rehab program that is approved within their state.
