General Question for the Week of January 29, 2024


What considerations should be taken into account when coding for the imaging of the inferior phrenic artery, especially concerning the various anomalous arterial variations that may exist, including different points of origin such as the aorta, celiac, or renal artery?


When imaging the inferior phrenic artery (IPA), the procedural report must be read carefully to determine the correct coding. Several anomalous arterial variations exist. The inferior phrenic arteries are paired vessels that may originate directly off of the aorta (T12 – L2 level) or be a branch of another vessel (i.e., inferior phrenic artery off the celiac, or inferior phrenic off the renal artery).
