There are several ways to cover the cost of Manchester drug addiction treatment. One payment method you may come across is a sliding fee scale (fee is based on income and other variables). This indicates that the rehab adjusts their fees based on the client?s income, yearly taxes and other financial variables; in the end, the cost that a single person pays may possibly 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 choose to help out an addict who would in any other case not be able to obtain treatment. Another reason for supplying this payment choice is that it provides the treatment facility with a tax deduction on the benefit of donating their services as charity.
