Medicaid is a kind of health care insurance available for those who are in certain income brackets which qualifies them to acquire this government funded insurance. Whether or not a person qualifies for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify simply because they earn an acceptable income. For instance, people who have a lot of dependents may be entitled to Medicaid regardless of whether they earn what would be described as a reasonable income. Medicaid could also cover the expense of rehabilitation, if a person has been abusing drugs or alcohol and requires rehabilitation. There are several drug and alcohol rehabilitation programs which accept Medicaid, but various states have different guidelines for what kinds of rehab are covered. Some states only cover outpatient rehab services for example while other states cover more extensive rehab say for example a residential stay in long-term alcohol and drug rehab program. If somebody is involved in drug abuse and desires help, they are able to use their Medicaid insurance coverage to obtain this help. If they do not have Medicaid and also don't have the money or some other kind of health insurance to pay for treatment, they can find out if they qualify for Medicaid and then enroll in an alcohol and drug rehab center that's approved inside their state.
