Medicaid is a kind of medical insurance available for many people who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether somebody qualifies for Medicaid doesn't only depend upon income however, and individuals shouldn't assume they don't qualify because they make a good income. By way of example, individuals who have a lot of dependents may qualify for Medicaid even when they make what would be considered a fair income. Medicaid can also cover the costs of treatment, when someone has been abusing drugs or alcohol and needs rehab. There are numerous drug and alcohol treatment centers which accept Medicaid, but different states have different rules for what sorts of rehab are covered. Certain states only cover outpatient rehab services for example while other states cover more extensive rehab like a residential stay in long-term drug rehab program. If someone is involved in drug use and desires help, they can use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid and in addition don't have the funds or some other kind of health care insurance to cover rehabilitation, they can determine if they qualify for Medicaid and then enroll in a drug and alcohol treatment program that is approved in their state.
