Medicaid is a kind of health insurance available for many people who are in specific income brackets which qualifies them to acquire this government funded insurance. Whether or not an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify simply because they earn a good income. For example, people who have quite a few dependents may be entitled to Medicaid even when they make what would be considered a sensible income. Medicaid could also cover the expenses of treatment, if a person has been abusing alcohol or drugs and requires treatment. There are lots of drug rehab centers which accept Medicaid, but different states have different rules for what forms of rehabilitation are covered. Certain states only include outpatient treatment services by way of example while other states cover more extensive rehab such as a residential stay in long-term alcohol and drug rehabilitation program. If a person is involved with drug abuse and needs help, they are able to use their Medicaid insurance coverage to get this help. If they do not have Medicaid and in addition don't have the money or some other kind of medical insurance to cover treatment, they can see if they are eligible for a Medicaid and then enroll in a drug and alcohol rehab center which is approved in their state.
