There are quite a few ways to cover the cost of Estill Springs drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on income and other factors). This implies that the rehab adjusts their costs based on the client?s revenue, yearly taxes and other financial factors; in the end, the price that one person pays may possibly not be the same as another. There are several 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 otherwise 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 merit of donating their services as charity.
