This means that the rehab adjusts their charges based on the client?s revenue, yearly taxes and other economic factors; in the end, the cost that one particular client pays might not be the same as another. There are a number of reasons why a drug rehab would select to provide a sliding fee scale to their clients. They may select to help out an addict who would otherwise not be able to receive treatment.
