Medicaid is a type of medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether a person qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify simply because they make a good income. By way of example, people who have a lot of dependents may be entitled to Medicaid even when they earn what might certainly be a reasonable income. Medicaid may also cover the expense of rehabilitation, when someone has been abusing alcohol or drugs and requires rehab. There are many alcohol and drug rehab programs which accept Medicaid, but various states have distinct guidelines for what kinds of treatment are covered. Some states only cover outpatient treatment services for instance while other states cover more extensive rehabilitation like a residential stay in long-term drug treatment program. If someone is involved with substance abuse and needs help, they are able to use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid and in addition don't have the cash or some other form of health insurance to cover treatment, they could see if they are eligible for a Medicaid and then enroll in a drug and alcohol rehabilitation facility that's approved within their state.
