Medicaid is a type of health insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether or not someone is qualified for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify simply because they make a good income. For example, men and women who have a lot of dependents may be entitled to Medicaid even if they make what might be described as a sensible income. Medicaid can also cover the costs of treatment, if a person has been abusing alcohol or drugs and requires treatment. There are numerous drug and alcohol rehabilitation programs which accept Medicaid, but different states have different rules for what types of rehabilitation are covered. Some states only cover outpatient rehab services by way of example while other states cover far more intensive treatment such as a residential stay in long-term drug rehabilitation facility. If a person is involved in drug abuse and wants help, they could use their Medicaid health coverage to get this help. If they do not have Medicaid and in addition don't have enough cash or another type of health insurance to pay for treatment, they can check if they are eligible for a Medicaid and then enroll in a drug treatment facility which is approved in their state.
