There are a lot of ways to cover the price of Tortilla Flat drug addiction treatment. One payment method you may discover is a sliding fee scale (fee is based on income and other aspects). This means that the rehab adjusts their fees based on the client?s earnings, yearly taxes and other economic components; in the end, the cost that one particular individual pays might not be the same as another. There are many reasons why a drug rehab would choose to present a sliding fee scale to their clients. They may select to help out an addict who would normally not be able to receive treatment. Another reason for offering this payment choice is that it provides the treatment facility with a tax deduction on the benefit of donating their services as charity.
