Which CPT® code is appropriate for complete noninvasive physiologic studies of both lower extremities?

The appropriate CPT® code for complete noninvasive physiologic studies of both lower extremities is indeed 93970. This code specifically describes noninvasive vascular studies that evaluate blood flow in the lower extremities, which is essential for diagnosing conditions such as peripheral artery disease.

In the context of the CPT coding system, 93970 covers the comprehensive assessment necessary for both legs, including measurements of arterial blood flow and possibly Doppler studies to assess the presence and severity of vascular issues. This complete study allows for a thorough analysis of circulation, delivering critical information for further clinical decision-making.

While the other codes pertain to noninvasive vascular studies, they either represent studies for specific segments or volume analyses, or they might denote a bilateral or modifier context (as seen in the fourth option). Therefore, 93970 stands out as the code that specifically addresses the complete assessment of both lower extremities in a cohesive manner.
