Medicaid is a medical insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify just because they make a reasonable income. For example, people who have many dependents may be entitled to Medicaid even if they earn what might certainly be a reasonable income. Medicaid can also cover the expense of rehabilitation, when someone has been abusing drugs or alcohol and requires rehabilitation. There are lots of drug and alcohol treatment centers which accept Medicaid, but various states have distinct guidelines for what kinds of rehabilitation are covered. Some states only cover outpatient rehab services for example while other states cover far more extensive treatment like a residential stay in long-term drug and alcohol rehab facility. If anyone is involved in drug abuse and wants help, they can use their Medicaid health coverage to obtain this help. If they do not have Medicaid and in addition don't have enough cash or any other kind of medical insurance to pay for rehab, they can see if they are eligible for a Medicaid and then enroll in an alcohol and drug rehab facility that is approved inside their state.
