Medicaid is a type of medical insurance available for many people who are in specific income brackets which qualifies them to receive this government funded insurance coverage. Whether or not someone qualifies for Medicaid doesn't only determined by income however, and people shouldn't assume they don't qualify because they earn a reasonable income. For instance, people who have quite a few dependents may be eligible for Medicaid even if they earn what would be considered a reasonable income. Medicaid may also cover the price of rehab, when someone has been abusing drugs or alcohol and requires rehab. There are numerous alcohol and drug rehab centers which accept Medicaid, but different states have distinct rules for what kinds of treatment are covered. Some states only include outpatient treatment services for example while other states cover more intensive rehabilitation say for example a residential stay in long-term drug and alcohol rehab program. If someone is involved in drug use and needs help, they're able to use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid and in addition don't have the cash or some other form of health care insurance to cover rehabilitation, they can check if they qualify for Medicaid and then enroll in an alcohol and drug rehab facility which is approved within their state.
