Medicaid is a health insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not someone qualifies for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify simply because they make a fair income. By way of example, people who have a lot of dependents may be entitled to Medicaid even though they make what can be considered a fair income. Medicaid could also cover the costs of treatment, when someone has been abusing drugs or alcohol and needs rehab. There are lots of drug and alcohol rehab centers which accept Medicaid, but different states have different rules for what kinds of rehabilitation are covered. Some states only cover outpatient treatment services for example while other states cover more intensive treatment say for example a residential stay in long-term drug and alcohol rehabilitation program. If someone is involved with drug abuse and desires help, they're able to use their Medicaid health coverage to acquire this help. If they do not have Medicaid plus don't have enough cash or any other kind of medical insurance to cover treatment, they can find out if they are eligible for a Medicaid and then sign up for a drug rehab center which is approved inside their state.
