Medicaid is a health insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance coverage. Whether an individual 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. For example, individuals who have quite a few dependents may be eligible for Medicaid even though they make what would be described as a reasonable income. Medicaid could also cover the costs of treatment, when someone has been abusing alcohol or drugs and requires rehab. There are many drug rehab centers which accept Medicaid, but various states have distinct guidelines for what kinds of rehab are covered. Some states only cover outpatient treatment services for example while other states cover far more extensive rehab like a residential stay in long-term alcohol and drug rehabilitation program. If someone is involved with drug use and wants help, they're able to use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid plus don't have the money or another form of medical health insurance to pay for rehabilitation, they can find out if they qualify for Medicaid and then enroll in a drug treatment center that is approved inside their state.
