Medicaid is a kind of health care insurance available for many people who are in certain income brackets which qualifies them to acquire this government provided insurance coverage. Whether or not an individual qualifies for Medicaid doesn't only depend on income however, and people shouldn't assume they don't qualify just because they earn an acceptable income. For instance, people who have a lot of dependents may be eligible for Medicaid even though they earn what can be described as a sensible income. Medicaid may also cover the price of rehabilitation, when someone has been abusing alcohol or drugs and needs rehab. There are several drug rehabilitation programs which accept Medicaid, but various states have distinct rules for what forms of rehab are covered. Certain states only cover outpatient treatment services for instance while other states cover far more intensive rehabilitation such as a residential stay in long-term drug treatment center. If somebody is involved in substance abuse and needs help, they are able to use their Medicaid insurance coverage to obtain this treatment. If they don't have Medicaid and in addition don't have enough cash or some other type of health care insurance to cover rehabilitation, they can check if they are eligible for a Medicaid and then enroll in a drug and alcohol rehab center that is approved within their state.
