"A patient undergoes UAE for fibroids. The left uterine artery is selectively catheterized, and embolization is performed (36247, 37243). Following the procedure, the catheter is repositioned into the ipsilateral internal iliac artery. Selective angiography confirms agenesis of the right uterine artery, which had been seen on the initial pelvic angiography at the start of the case. The catheter is removed; no embolization is performed on the right side." Is it appropriate to add code 36245 for the catheterization of the right internal iliac artery, considering that it was not performed for embolization?
