Medicaid is a type of health insurance available for those who are in certain income brackets which qualifies them to obtain this government funded insurance. Whether somebody is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't assume they don't qualify just because they make an acceptable income. For example, men and women who have many dependents may be eligible for Medicaid even when they earn what would be considered a fair income. Medicaid can also cover the costs of treatment, when someone has been abusing alcohol or drugs and requires treatment. There are numerous drug rehabilitation programs which accept Medicaid, but different states have different rules for what sorts of rehab are covered. Certain states only include outpatient rehab services for instance while other states cover far more intensive treatment like a residential stay in long-term drug rehab center. If anyone is involved with drug abuse and needs help, they're able to use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid and in addition don't have enough cash or another form of medical insurance to cover rehab, they can check if they are eligible for a Medicaid and then sign up for a drug rehab facility that is approved within their state.
