Medicaid is a medical health insurance available for many people who are in specific income brackets which qualifies them to obtain this government funded insurance coverage. Whether someone is qualified for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify simply because they make a good income. By way of example, people who have quite a few dependents may be entitled to Medicaid regardless of whether they make what can be described as a reasonable income. Medicaid may also cover the expense of treatment, if someone has been abusing alcohol or drugs and needs rehabilitation. There are numerous alcohol and drug treatment centers which accept Medicaid, but different states have distinct rules for what types of treatment are covered. Certain states only include outpatient treatment services as an example while other states cover far more extensive rehab such as a residential stay in long-term alcohol and drug treatment center. If a person is involved with drug abuse and wants help, they can use their Medicaid insurance coverage to obtain this help. If they don't have Medicaid plus don't have the funds or some other type of medical insurance to cover rehabilitation, they can see if they are eligible for a Medicaid and then sign up for a drug rehab program which is approved in their state.
