There are several ways to cover the price of Olin drug addiction treatment. One payment method you may uncover is a sliding fee scale (fee is based on earnings and other factors). This implies that the rehab adjusts their charges based on the client?s income, yearly taxes and other economic variables; in the end, the cost that one client pays may not be the same as another. There are several reasons why a drug rehab would select to present a sliding fee scale to their clients. They may choose to help out an addict who would otherwise not be able to obtain treatment. Another reason for offering this payment option is that it provides the treatment facility with a tax deduction on the benefit of donating their services as charity.
