Medicaid is a form of health care insurance available for individuals who are in specific income brackets which qualifies them to obtain this government funded insurance. Whether or not someone is qualified for Medicaid doesn't only determined by income however, and people shouldn't presume they don't qualify because they earn a good income. By way of example, people who have many dependents may be eligible for Medicaid regardless of whether they earn what might be described as a fair income. Medicaid can also cover the price of treatment, if someone has been abusing drugs or alcohol and requires rehabilitation. There are many alcohol and drug rehab centers which accept Medicaid, but different states have distinct guidelines for what forms of treatment are covered. Some states only cover outpatient rehabilitation services for instance while other states cover more intensive treatment such as a residential stay in long-term drug rehab program. If a person is involved in substance abuse and needs help, they are able to use their Medicaid insurance coverage to get this help. If they don't have Medicaid and also don't have the cash or some other form of medical insurance to cover rehab, they could see if they qualify for Medicaid and then sign up for a drug rehabilitation center that's approved within their state.
