Medicaid is a type of health insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance coverage. Whether a person is qualified for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify because they make an acceptable income. For example, people who have a lot of dependents may be entitled to Medicaid even when they make what can be considered a sensible income. Medicaid also can cover the expenses of rehab, if someone has been abusing drugs or alcohol and requires rehabilitation. There are numerous alcohol and drug treatment centers which accept Medicaid, but different states have different rules for what kinds of rehab are covered. Some states only cover outpatient rehabilitation services as an example while other states cover far more intensive rehab say for example a residential stay in long-term drug rehabilitation program. If a person is involved in drug abuse and wants help, they're able to use their Medicaid health coverage to obtain this help. If they don't have Medicaid plus don't have the money or any other form of health insurance to cover treatment, they can check if they are eligible for a Medicaid and then enroll in a drug and alcohol rehabilitation center which is approved within their state.
