There are quite a few ways to cover the cost of Santiago drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on earnings and other factors). This implies that the rehab adjusts their charges based on the client?s income, yearly taxes and other monetary components; in the end, the price that one client pays might not be the same as another. There are a number of reasons why a drug rehab would choose to provide a sliding fee scale to their clients. They may choose to help out an addict who would often not be able to acquire treatment. Another reason for supplying this payment choice is that it provides the treatment facility with a tax deduction on the merit of donating their services as charity.
