Medicaid is a kind of medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they earn a good income. As an example, men and women who have many dependents may qualify for Medicaid even if they earn an amount be described as a sensible income. Medicaid also can cover the expense of treatment, when someone has been abusing alcohol or drugs and requires rehab. There are numerous drug and alcohol rehabilitation facilities which accept Medicaid, but different states have different rules for what types of treatment are covered. Some states only include outpatient treatment services for example while other states cover far more extensive rehab say for example a residential stay in long-term drug treatment program. If someone is involved in substance abuse and wants help, they could use their Medicaid insurance coverage to get this treatment. If they do not have Medicaid and also don't have the money or any other form of medical health insurance to cover treatment, they can check if they qualify for Medicaid and then sign up for a drug rehab center that is approved inside their state.
