Medicaid is a health care insurance available for individuals who are in specific income brackets which qualifies them to receive this government provided insurance coverage. Whether an individual qualifies for Medicaid doesn't only determined by their earnings however, and people shouldn't presume they don't qualify because they make a reasonable income. As an example, individuals who have a lot of dependents may be eligible for Medicaid even though they make what can be described as a sensible income. Medicaid may also cover the price of rehab, if someone has been abusing alcohol or drugs and requires treatment. There are many drug and alcohol rehabilitation facilities which accept Medicaid, but different states have different rules for what kinds of rehabilitation are covered. Some states only cover outpatient rehabilitation services as an example while other states cover more extensive rehabilitation like a residential stay in long-term drug and alcohol rehab center. If someone is involved in drug use and desires help, they're able to use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid and in addition don't have the cash or some other kind of medical health insurance to pay for rehab, they can determine if they qualify for Medicaid and then enroll in an alcohol and drug rehab center that's approved within their state.
