Medicaid is a health insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance coverage. Whether an individual is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify just because they make an acceptable income. As an example, individuals who have quite a few dependents may be eligible for Medicaid even if they earn what might be considered a reasonable income. Medicaid could also cover the expenses of rehab, if a person has been abusing drugs or alcohol and requires rehab. There are many drug treatment programs which accept Medicaid, but different states have different rules for what sorts of rehabilitation are covered. Some states only cover outpatient treatment services for example while other states cover far more intensive rehabilitation like a residential stay in long-term drug rehabilitation center. If anyone is involved in substance abuse and desires help, they could use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid and also don't have enough cash or some other type of health care insurance to pay for rehabilitation, they can check if they are eligible for a Medicaid and then enroll in an alcohol and drug treatment facility that's approved within their state.
