Medicaid is a medical insurance available for individuals who are in certain income brackets which qualifies them to acquire this government provided insurance. Whether a person is qualified for Medicaid doesn't only determined by income however, and individuals shouldn't assume they don't qualify because they make a reasonable income. As an example, people who have quite a few dependents may be entitled to Medicaid regardless of whether they make what can be described as a reasonable income. Medicaid also can cover the costs of rehabilitation, when someone has been abusing drugs or alcohol and needs treatment. There are lots of drug and alcohol rehab centers which accept Medicaid, but various states have different rules for what sorts of treatment are covered. Certain states only cover outpatient rehab services for instance while other states cover more extensive rehabilitation say for example a residential stay in long-term alcohol and drug rehabilitation center. If someone is involved in drug abuse and wants help, they can use their Medicaid health coverage to get this treatment. If they don't have Medicaid and in addition don't have the cash or any other type of health insurance to pay for treatment, they could check if they qualify for Medicaid and then sign up for an alcohol and drug treatment facility which is approved in their state.
