Medicaid is a medical insurance available for individuals who are in specific income brackets which qualifies them to obtain this government provided insurance coverage. Whether an individual is qualified for Medicaid doesn't only depend on income however, and individuals shouldn't assume they don't qualify because they earn a good income. For example, people who have many dependents may be entitled to Medicaid even if they earn what might certainly be a fair income. Medicaid can also cover the expenses of rehabilitation, when someone has been abusing alcohol or drugs and requires rehabilitation. There are lots of drug and alcohol treatment facilities which accept Medicaid, but various states have different rules for what types of rehabilitation are covered. Certain states only cover outpatient rehab services for example while other states cover far more intensive rehab such as a residential stay in long-term drug treatment facility. If somebody is involved in drug abuse and needs help, they can use their Medicaid insurance coverage to acquire this treatment. If they do not have Medicaid and in addition don't have the funds or some other type of medical insurance to cover treatment, they can find out if they qualify for Medicaid and then sign up for an alcohol and drug rehabilitation facility which is approved within their state.
