Both practitioners and reviewers need to understand where the other is coming from. The key is the proper sharing and documentation of appropriate information in a concise, articulate fashion. Many examples of how to present different kinds of patients—such as inpatients, partial hospital patients, substance abusers, and outpatients—take up most of the book. Clear thinking leads not only to economically sustainable treatment but to better treatment, Fauman argues. A chart that is well documented to allow for the possibility of a retrospective utilization review would also help in any malpractice defense, should there be a bad clinical outcome.
