There are a lot of ways to cover the price of Haydenville drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on earnings and other components). This means that the rehab adjusts their charges based on the client?s earnings, yearly taxes and other economic components; in the end, the price that one person pays might not be the same as another. There are various reasons why a drug rehab would select to provide 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.
