Medicaid is a health insurance available for many people who are in certain income brackets which qualifies them to obtain this government provided insurance. Whether or not somebody is qualified for Medicaid doesn't only depend upon their earnings however, and people shouldn't assume they don't qualify because they earn an acceptable income. For example, individuals who have quite a few dependents may qualify for Medicaid even when they earn what can be considered a reasonable income. Medicaid could also cover the expenses of treatment, when someone has been abusing alcohol or drugs and needs treatment. There are many alcohol and drug rehabilitation facilities which accept Medicaid, but various states have distinct rules for what types of treatment are covered. Some states only include outpatient treatment services for example while other states cover far more extensive rehabilitation such as a residential stay in long-term alcohol and drug treatment center. If someone is involved in drug abuse and needs help, they can use their Medicaid insurance coverage to acquire this help. If they do not have Medicaid and in addition don't have the money or any other form of medical insurance to pay for rehabilitation, they can see if they are eligible for a Medicaid and then enroll in a drug treatment program which is approved within their state.
