This course reviews the 2021 guidelines as they pertain to new and established psychiatry office patients. The new rules for coding based on time are discussed as well as the new methodology for calculating the medical decision-making. Using psychiatry clinical examples, we illustrate how to select the correct level of care for new and established office patients, then show how to document each encounter as expeditiously as possible. The conventions for using the initial psychiatric evaluation codes, psychotherapy codes and psychotherapy + E/M codes in the office setting are also reviewed.
