A patient with PVD and non-healing ulceration of the right heel has diagnostic angiographies performed in September of 2021, but intervention is delayed due to recurrent illness. In December of that same year, interventions are scheduled for the right popliteal and tibial/peroneal trunk. The radiologist performs angiography to "re-evaluate the anatomy given the three-month delay between prior angiography and now". IVUS was performed for sizing purposes, after which interventions were performed. Current angiographic findings are largely consistent with prior findings. Can 75710-59 be reported, or is this essentially a guiding shot?
