Medicaid is a form of medical insurance available for those who are in specific income brackets which qualifies them to obtain this government provided insurance. Whether a person is qualified for Medicaid doesn't only depend upon income however, and people shouldn't assume they don't qualify just because they make a good income. As an example, individuals who have many dependents may be eligible for Medicaid regardless of whether they make what can be described as a sensible income. Medicaid may also cover the expenses of treatment, if a person has been abusing drugs or alcohol and requires rehabilitation. There are numerous alcohol and drug rehabilitation centers which accept Medicaid, but different states have different guidelines for what types of rehab are covered. Some states only cover outpatient treatment services for example while other states cover far more intensive treatment say for example a residential stay in long-term drug treatment facility. If someone is involved with drug abuse and needs help, they're able to use their Medicaid insurance coverage to acquire this help. If they don't have Medicaid and in addition don't have enough cash or another kind of medical insurance to cover rehab, they can check if they are eligible for a Medicaid and then enroll in a drug rehabilitation center that is approved in their state.
