Medicaid is a type of medical insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify just because they make a good income. For instance, people who have quite a few dependents may be entitled to Medicaid regardless of whether they make what can be described as a fair income. Medicaid also can cover the expenses of treatment, when someone has been abusing alcohol or drugs and requires rehab. There are several drug treatment programs which accept Medicaid, but various states have different rules for what types of rehab are covered. Some states only cover outpatient rehab services by way of example while other states cover more intensive rehab say for example a residential stay in long-term drug rehabilitation facility. If someone is involved in substance abuse and desires help, they are able to use their Medicaid health coverage to get this help. If they don't have Medicaid plus don't have the cash or some other kind of medical health insurance to cover treatment, they could find out if they qualify for Medicaid and then enroll in an alcohol and drug treatment facility that's approved inside their state.
