Medicaid is a kind of health care insurance available for many people who are in certain income brackets which qualifies them to receive this government funded insurance. Whether an individual qualifies for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify simply because they make a good income. As an example, individuals who have quite a few dependents may be entitled to Medicaid even if they make what can be considered a reasonable income. Medicaid also can cover the price of treatment, when someone has been abusing drugs or alcohol and needs rehabilitation. There are numerous alcohol and drug rehab programs which accept Medicaid, but different states have different rules for what kinds of treatment are covered. Some states only include outpatient rehabilitation services for example while other states cover more extensive treatment like a residential stay in long-term drug rehab program. If a person is involved in drug abuse and needs help, they are able to use their Medicaid insurance coverage to acquire this help. If they do not have Medicaid plus don't have the funds or some other form of health insurance to cover rehabilitation, they could find out if they qualify for Medicaid and then sign up for a drug treatment facility that is approved within their state.
