There are a lot of ways to cover the expense of Venus 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 charges based on the client?s income, yearly taxes and other monetary factors; in the end, the cost that one client pays may not be the same as another. There are various reasons why a drug rehab would select to offer a sliding fee scale to their clients. They may select to help out an addict who would in any other case not be able to receive 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.
