What does the term "percutaneous" refer to in CPT coding?

The term "percutaneous" refers specifically to procedures that are performed through the skin. This technique is often associated with minimally invasive surgical approaches, meaning that it typically involves smaller incisions or entry points compared to traditional open surgery. Procedures categorized as percutaneous often utilize imaging guidance, such as ultrasound or fluoroscopy, to accurately target areas within the body while minimizing damage to surrounding tissues.

This term emphasizes the approach and technique used in the procedure rather than the need for hospitalization or the extent of tissue removal, making it distinct from other options. For instance, procedures involving open incisions or extensive tissue removal are typically more invasive and may not be classified as percutaneous. Thus, understanding the definition of percutaneous is essential in correctly interpreting CPT codes and selecting the appropriate coding for various surgical procedures.
