Medicaid is a type of medical insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether someone qualifies for Medicaid doesn't only depend upon their earnings however, and individuals shouldn't assume they don't qualify because they earn a reasonable income. As an example, individuals who have a lot of dependents may qualify for Medicaid even when they make what would be considered a fair income. Medicaid could also cover the expenses of rehabilitation, when someone has been abusing alcohol or drugs and needs rehab. There are lots of alcohol and drug treatment facilities which accept Medicaid, but various states have different guidelines for what forms of rehabilitation are covered. Some states only include outpatient rehab services for instance while other states cover more extensive rehab like a residential stay in long-term drug treatment program. If someone is involved in drug abuse and desires help, they are able to use their Medicaid health coverage to acquire this treatment. If they do not have Medicaid plus don't have the funds or another type of health insurance to pay for treatment, they can find out if they qualify for Medicaid and then enroll in a drug and alcohol treatment facility which is approved within their state.
