Medicaid is a type of health insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether or not an individual is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify simply because they make a reasonable income. As an example, individuals who have a lot of dependents may be entitled to Medicaid even if they earn what can be considered a fair income. Medicaid could also cover the costs of rehabilitation, if someone has been abusing alcohol or drugs and needs treatment. There are many drug treatment centers which accept Medicaid, but different states have different rules for what types of rehabilitation are covered. Some states only include outpatient treatment services as an example while other states cover more intensive rehab say for example a residential stay in long-term drug and alcohol rehab center. If someone is involved with drug abuse and needs help, they can use their Medicaid health coverage to acquire this help. If they don't have Medicaid and in addition don't have the money or any other form of health insurance to pay for rehab, they could find out if they qualify for Medicaid and then enroll in a drug rehab facility which is approved in their state.
