Medicaid is a health care insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether or not a person qualifies for Medicaid doesn't only depend upon income however, and individuals shouldn't presume they don't qualify because they make an acceptable income. For example, people who have many dependents may qualify for Medicaid even though they earn what would be described as a fair income. Medicaid can also cover the costs of rehabilitation, when someone has been abusing drugs or alcohol and requires rehab. There are many alcohol and drug rehabilitation programs which accept Medicaid, but different states have different rules for what forms of rehabilitation are covered. Some states only include outpatient rehab services for instance while other states cover far more intensive rehab like a residential stay in long-term drug and alcohol rehab center. If anyone is involved with drug use and needs help, they're able to use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid and also don't have the money or some other kind of health care insurance to cover rehab, they could check if they are eligible for a Medicaid and then enroll in a drug rehabilitation program that is approved within their state.
