There are several ways to cover the cost of Independence drug addiction treatment. One payment method you may find is a sliding fee scale (fee is based on earnings and other variables). This means that the rehab adjusts their charges based on the client?s revenue, yearly taxes and other monetary factors; in the end, the price that a single person pays may not be the same as another. There are various reasons why a drug rehab would choose to offer a sliding fee scale to their clients. They may select to help out an addict who would normally not be able to obtain treatment. Another reason for offering this payment possibility is that it provides the treatment facility with a tax deduction on the benefit of donating their services as charity.
