Medicaid is a form of health insurance available for those who are in specific income brackets which qualifies them to obtain this government funded insurance. Whether or not an individual is qualified for Medicaid doesn't only depend upon their earnings however, and individuals shouldn't presume they don't qualify because they earn a good income. As an example, individuals who have many dependents may qualify for Medicaid even when they earn what can be considered a fair income. Medicaid may also cover the costs of treatment, if someone has been abusing alcohol or drugs and requires treatment. There are several drug and alcohol rehab facilities which accept Medicaid, but various states have distinct guidelines for what types of rehabilitation are covered. Some states only cover outpatient rehab services for instance while other states cover more extensive rehabilitation like a residential stay in long-term drug rehab program. If somebody is involved in substance abuse and wants help, they're able to use their Medicaid health coverage to obtain this treatment. If they don't have Medicaid and in addition don't have enough cash or another type of medical health insurance to cover rehabilitation, they can see if they qualify for Medicaid and then sign up for a drug and alcohol rehabilitation center which is approved inside their state.
