Medicaid is a form of health insurance available for individuals who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether someone is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify because they earn a fair income. For instance, people who have quite a few dependents may be eligible for Medicaid even if they make an amount be considered a sensible income. Medicaid could also cover the expenses of rehab, if someone has been abusing alcohol or drugs and requires rehab. There are lots of drug and alcohol rehabilitation programs which accept Medicaid, but various states have different rules for what kinds of rehabilitation are covered. Some states only include outpatient rehabilitation services for instance while other states cover more intensive treatment such as a residential stay in long-term drug and alcohol treatment program. If somebody is involved in drug use and desires help, they're able to use their Medicaid health coverage to obtain this help. If they do not have Medicaid and also don't have enough cash or any other kind of medical insurance to cover treatment, they can see if they are eligible for a Medicaid and then enroll in a drug rehabilitation facility which is approved in their state.
