Medicaid is a type of medical insurance available for individuals who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not an individual qualifies for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify simply because they earn an acceptable income. For example, men and women who have a lot of dependents may be entitled to Medicaid even if they earn what might certainly be a sensible income. Medicaid can also cover the costs of rehab, if someone has been abusing alcohol or drugs and needs rehab. There are lots of alcohol and drug rehabilitation programs which accept Medicaid, but different states have different rules for what types of rehab are covered. Some states only include outpatient treatment services for example while other states cover far more intensive rehab say for example a residential stay in long-term drug and alcohol treatment facility. If a person is involved in drug use and desires help, they could use their Medicaid health coverage to obtain this help. If they do not have Medicaid and in addition don't have the funds or any other kind of health care insurance to cover treatment, they could determine if they qualify for Medicaid and then enroll in a drug and alcohol rehab program which is approved within their state.
