There are quite a few ways to cover the price of Rector drug addiction treatment. One payment method you may discover is a sliding fee scale (fee is based on income and other variables). This implies that the rehab adjusts their charges based on the client?s income, yearly taxes and other financial factors; in the end, the expense that a single person pays may 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 often not be able to obtain treatment. Another reason for offering this payment possibility is that it offers the treatment facility with a tax deduction on the merit of donating their services as charity.
