Medicaid is a form of health care insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether somebody is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify just because they make a reasonable income. As an example, people who have many dependents may be entitled to Medicaid even when they make an amount be considered a fair income. Medicaid can also cover the expense of treatment, if someone has been abusing alcohol or drugs and requires rehabilitation. There are several drug rehabilitation centers which accept Medicaid, but various states have different rules for what sorts of rehabilitation are covered. Some states only cover outpatient treatment services for instance while other states cover more extensive rehab say for example a residential stay in long-term drug and alcohol rehab program. If a person is involved with drug use and needs help, they can use their Medicaid insurance coverage to get this help. If they don't have Medicaid and in addition don't have the cash or some other form of medical insurance to cover rehab, they could determine if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation center that's approved inside their state.
