Medicaid is a type of health insurance available for many people who are in certain income brackets which qualifies them to receive this government provided insurance. Whether an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify because they make an acceptable income. By way of example, people who have a lot of dependents may be entitled to Medicaid even when they make what would be considered a sensible income. Medicaid can also cover the expenses of rehab, when someone has been abusing alcohol or drugs and needs treatment. There are several drug and alcohol rehabilitation programs which accept Medicaid, but various states have distinct rules for what sorts of rehab are covered. Some states only cover outpatient treatment services as an example while other states cover more intensive rehabilitation say for example a residential stay in long-term drug treatment center. If someone is involved with drug abuse and desires help, they can use their Medicaid health coverage to acquire this help. If they don't have Medicaid and in addition don't have the cash or any other kind of medical insurance to pay for treatment, they can find out if they are eligible for a Medicaid and then sign up for a drug and alcohol rehabilitation facility which is approved within their state.
