Medicaid is a type of medical health insurance available for many people who are in specific income brackets which qualifies them to receive this government provided insurance coverage. Whether or not an individual qualifies for Medicaid doesn't only depend on their earnings however, and people shouldn't presume they don't qualify simply because they earn an acceptable income. As an example, individuals who have quite a few dependents may be eligible for Medicaid even if they earn what would be considered a fair income. Medicaid also can cover the expenses of rehab, when someone has been abusing drugs or alcohol and requires rehabilitation. There are several drug and alcohol treatment centers which accept Medicaid, but various states have different guidelines for what forms of rehab are covered. Some states only cover outpatient rehabilitation services for instance while other states cover far more extensive rehab such as a residential stay in long-term drug and alcohol rehabilitation facility. If somebody is involved with substance abuse and desires help, they are able to use their Medicaid insurance coverage to acquire this treatment. If they don't have Medicaid plus don't have enough cash or some other type of health insurance to pay for rehabilitation, they can see if they qualify for Medicaid and then enroll in a drug and alcohol rehab center which is approved within their state.
