It is not unusual for individuals engaged in substance abuse to deplete all resources on their addiction. When it is time to get help in an Oak Park, Illinois drug rehabilitation center, there may be no money left to cover the costs of such treatment. If the individual is not covered by private health insurance in Oak Park, Illinois, they will need to self pay in order to obtain rehab services. Self pay implies that the person will need to come up with the resources to pay for the costs of drug rehabilitation, costs which can vary depending on the treatment option which is being considered. If the self pay option is the only way to pay for drug treatment, prospective treatment clients can work with treatment counselors to find out if any payment assistance can be offered in the form of a reduced rate or slide scale fee. These payment assistance options for self pay clients are typically decided based on each individual's circumstances which can include personal income and other potential sources of income.
