There are many ways to cover the cost of Ash drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on earnings and other components). This signifies that the rehab adjusts their charges based on the client?s income, yearly taxes and other financial components; in the end, the price that a single person pays might not be the same as another. There are numerous reasons why a drug rehab would select to offer a sliding fee scale to their clients. They may select to help out an addict who would otherwise not be able to acquire treatment. Another reason for offering this payment possibility is that it offers the treatment facility with a tax deduction on the benefit of donating their services as charity.
