Medicaid is a kind of medical health insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not someone qualifies for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify simply because they make an acceptable income. For example, people who have a lot of dependents may be eligible for Medicaid regardless of whether they earn what would certainly be a fair income. Medicaid may also cover the costs of treatment, if a person has been abusing alcohol or drugs and requires treatment. There are several drug rehabilitation programs which accept Medicaid, but various states have distinct rules for what forms of rehab are covered. Certain states only include outpatient rehab services for example while other states cover far more intensive rehab such as a residential stay in long-term drug treatment center. If somebody is involved with drug abuse and desires help, they can use their Medicaid health coverage to get this treatment. If they don't have Medicaid plus don't have enough cash or some other type of medical health insurance to pay for rehab, they can determine if they qualify for Medicaid and then sign up for a drug rehab facility that is approved in their state.
