There are quite a few ways to cover the price of Kelly drug addiction treatment. One payment method you may discover is a sliding fee scale (fee is based on income and other variables). This indicates that the rehab adjusts their fees based on the client?s earnings, yearly taxes and other financial components; in the end, the cost that one particular client pays may not be the same as another. There are several reasons why a drug rehab would select to provide a sliding fee scale to their clients. They may select to help out an addict who would often not be able to obtain treatment. Another reason for providing this payment choice is that it provides the treatment facility with a tax deduction on the merit of donating their services as charity.
