There are quite a few ways to cover the expense of Strum drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on income and other factors). This indicates that the rehab adjusts their fees based on the client?s income, yearly taxes and other economic factors; in the end, the cost that a single person pays may not be the same as another. There are many reasons why a drug rehab would select to provide 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 selection is that it offers the treatment facility with a tax deduction on the benefit of donating their services as charity.
