It is not uncommon for people engaged in substance abuse to exhaust all financial resources on their addiction. When it is time to get help in a Naperville, IL. drug treatment center, there may be no money left over to cover the costs of such treatment. If the individual is not covered by private health insurance in Naperville, IL., they will need to self pay in order to receive rehab services. Self pay means that the individual 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 rehabilitation, potential 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 usually determined based on each individual's circumstances which can include household income as well as other possible sources of income.
