There are quite a few ways to cover the cost of Greenfield Town drug addiction treatment. One payment method you may find is a sliding fee scale (fee is based on earnings and other variables). This indicates that the rehab adjusts their charges based on the client?s revenue, yearly taxes and other financial variables; in the end, the price that a single client pays might not be the same as another. There are many reasons why a drug rehab would choose to offer a sliding fee scale to their clients. They may choose to help out an addict who would normally not be able to receive 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.
