There are many ways to cover the cost of Annville drug addiction treatment. One payment method you may uncover is a sliding fee scale (fee is based on earnings and other components). This signifies that the rehab adjusts their fees based on the client?s income, yearly taxes and other monetary factors; in the end, the expense that one particular individual pays may not be the same as another. There are several reasons why a drug rehab would choose to offer 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 supplying this payment option is that it provides the treatment facility with a tax deduction on the merit of donating their services as charity.
