Medicaid is a form of health insurance available for those who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether or not an individual is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify just because they earn a fair income. For instance, individuals who have quite a few dependents may be entitled to Medicaid even though they earn what can certainly be a sensible income. Medicaid may also cover the price of treatment, if someone has been abusing alcohol or drugs and requires rehabilitation. There are many drug rehab centers which accept Medicaid, but various states have different rules for what types of rehab are covered. Some states only cover outpatient treatment services for example while other states cover far more intensive rehab such as a residential stay in long-term drug treatment facility. If someone is involved in drug use and wants help, they could use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid and also don't have the money or some other form of medical 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.
