Medicaid is a type of medical insurance available for those who are in specific income brackets which qualifies them to acquire this government funded insurance coverage. Whether or not someone qualifies for Medicaid doesn't only determined by their earnings however, and individuals shouldn't assume they don't qualify just because they make a good income. For example, people who have a lot of dependents may qualify for Medicaid even if they make what can be considered a reasonable income. Medicaid could also cover the expenses of treatment, if someone has been abusing drugs or alcohol and requires rehabilitation. There are many alcohol and drug rehab centers which accept Medicaid, but various states have different guidelines for what types of rehab are covered. Some states only include outpatient treatment services for instance while other states cover far more intensive rehab say for example a residential stay in long-term drug and alcohol rehab program. If a person is involved in drug use and desires help, they are able to use their Medicaid health coverage to acquire this treatment. If they don't have Medicaid plus don't have enough cash or any other kind of medical insurance to cover rehabilitation, they could check if they qualify for Medicaid and then enroll in an alcohol and drug rehabilitation facility which is approved within their state.
