Medicaid is a medical health insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not an individual is qualified for Medicaid doesn't only determined by income however, and people shouldn't presume they don't qualify because they make a reasonable income. For instance, people who have quite a few dependents may qualify for Medicaid even if they make what can be considered a fair income. Medicaid also can cover the costs of treatment, if a person has been abusing alcohol or drugs and requires rehab. There are lots of alcohol and drug rehab facilities which accept Medicaid, but different states have distinct guidelines for what sorts of treatment are covered. Some states only include outpatient treatment services for example while other states cover far more extensive rehabilitation like a residential stay in long-term drug treatment facility. If anyone is involved with drug use and needs help, they're able to use their Medicaid health coverage to get this treatment. If they do not have Medicaid and also don't have the money or some other kind of medical insurance to cover treatment, they can check if they qualify for Medicaid and then enroll in a drug treatment facility which is approved in their state.
