There are several ways to cover the cost of Southampton drug addiction treatment. One payment method you may discover is a sliding fee scale (fee is based on income and other aspects). This implies that the rehab adjusts their costs based on the client?s income, yearly taxes and other monetary variables; in the end, the expense that one particular person pays may not be the same as another. There are a number of reasons why a drug rehab would select to present a sliding fee scale to their clients. They may choose to help out an addict who would normally not be able to obtain treatment. Another reason for offering this payment option is that it provides the treatment facility with a tax deduction on the merit of donating their services as charity.
