There are a lot of ways to cover the expense of Warren drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on earnings and other variables). This means that the rehab adjusts their costs based on the client?s income, yearly taxes and other economic factors; in the end, the cost that one client pays may not be the same as another. There are many reasons why a drug rehab would select to supply a sliding fee scale to their clients. They may select to help out an addict who would otherwise not be able to receive treatment. Another reason for supplying this payment selection is that it provides the treatment facility with a tax deduction on the merit of donating their services as charity.
