Medicaid is a form of health care insurance available for individuals who are in certain income brackets which qualifies them to receive this government provided insurance. Whether somebody is qualified for Medicaid doesn't only determined by their earnings however, and people shouldn't assume they don't qualify just because they earn a fair income. As an example, individuals who have a lot of dependents may be eligible for Medicaid even though they earn what would be described as a reasonable income. Medicaid could also cover the price of treatment, if someone has been abusing drugs or alcohol and requires rehab. There are several drug rehab centers which accept Medicaid, but various states have different rules for what kinds of treatment are covered. Some states only cover outpatient rehab services for example while other states cover more extensive treatment such as a residential stay in long-term drug rehabilitation program. If someone is involved in substance abuse and needs help, they can use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and in addition don't have the funds or another type of health insurance to pay for rehab, they can determine if they qualify for Medicaid and then enroll in an alcohol and drug rehabilitation facility which is approved inside their state.
