There are a lot of ways to cover the expense of Altamont drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on earnings and other variables). This indicates that the rehab adjusts their fees based on the client?s earnings, yearly taxes and other monetary variables; in the end, the cost that a single client pays may not be the same as another. There are a number of reasons why a drug rehab would choose to present a sliding fee scale to their clients. They may choose to help out an addict who would often not be able to obtain treatment. Another reason for providing this payment choice is that it offers the treatment facility with a tax deduction on the merit of donating their services as charity.
