There are many ways to cover the cost of Kantner drug addiction treatment. One payment method you may uncover is a sliding fee scale (fee is based on income and other aspects). This indicates that the rehab adjusts their fees based on the client?s earnings, yearly taxes and other monetary variables; in the end, the price that one person pays may not be the same as another. There are various 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 receive treatment. Another reason for providing this payment possibility is that it offers the treatment facility with a tax deduction on the benefit of donating their services as charity.
