Medicaid is a form of medical health insurance available for those who are in certain income brackets which qualifies them to acquire this government provided insurance coverage. Whether a person qualifies for Medicaid doesn't only depend on income however, and people shouldn't presume they don't qualify because they earn an acceptable income. By way of example, people who have quite a few dependents may be entitled to Medicaid even when they make what can be considered a sensible income. Medicaid may also cover the expenses of rehab, when someone has been abusing alcohol or drugs and requires treatment. There are lots of drug and alcohol rehabilitation centers which accept Medicaid, but various states have different rules for what sorts of rehabilitation are covered. Certain states only cover outpatient treatment services for instance while other states cover more intensive treatment say for example a residential stay in long-term drug treatment center. If a person is involved with drug abuse and wants help, they are able to use their Medicaid insurance coverage to get this treatment. If they don't have Medicaid plus don't have the money or another form of medical insurance to cover rehabilitation, they can check if they are eligible for a Medicaid and then enroll in a drug rehab facility that's approved inside their state.
