Medicaid is a kind of medical health insurance available for many people who are in certain income brackets which qualifies them to receive this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only determined by their earnings however, and people shouldn't presume they don't qualify simply because they earn a fair income. For example, individuals who have quite a few dependents may qualify for Medicaid even if they earn what would be considered a reasonable income. Medicaid can also cover the costs of rehabilitation, when someone has been abusing alcohol or drugs and needs rehab. There are lots of alcohol and drug rehab centers which accept Medicaid, but various states have distinct guidelines for what sorts of rehabilitation are covered. Some states only cover outpatient rehab services for instance while other states cover more intensive rehab such as a residential stay in long-term drug and alcohol rehab facility. If somebody is involved in drug use and needs help, they could use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid and also don't have the money or any other kind of health insurance to pay for rehabilitation, they could find out if they qualify for Medicaid and then enroll in a drug rehabilitation center which is approved in their state.
