Using Complexity-Based CPT Codes

How does one go about selecting the appropriate level of complexity for each patient evaluation? We’re glad you asked. This article details the four main evaluation complexity factors, along with a few sub-factors.

Selecting the Right Level of Evaluation Complexity

1. Patient History

2. Depth and results of examination and use of standardized tests and measures

  • Expected progression
  • Objective findings

3. Clinical presentation

  • Status of the current condition
  • Mechanism of the current condition

4. Clinical decision-making

  • Goal establishment
  • Prognosis and probable outcome

Vocabulary

Really quick, before we jump into the defining characteristics of each complexity level, let’s define a few terms that’ll pop up throughout this post:

  • Body Regions: Refers to areas of the body, such as head, neck, back, lower extremities, upper extremities, and trunk.
  • Body Systems: Includes the circulatory, skeletal, muscular, nervous, respiratory, immune, excretory, integumentary, lymphatic, cardiovascular, reproductive, and digestive systems.
  • Body Structures: Refers to the body’s structural or anatomical parts (e.g., organs or limbs), which are classified according to body systems.
  • Body Functions: Refers to the physiological functions of body systems.

Now, let’s get into the nitty-gritty details associated with each level of evaluation complexity.
