For percutaneous transluminal angioplasty of the left superior segmental renal artery and the left inferior segmental renal artery, is it appropriate to code both angioplasties with 35471 and applying -59 modifier on the additional PTA? If so, would both S&I codes be 75966 with a -59 modifier applied to the additional S&I, or would 75968 be more appropriate for the additional S&I? As for the catheter placement, SIR guide shows 3rd order 36247 for segmental renal branches; however, Medlearn IR Coder shows 2nd order 36246. Any advice would be greatly appreciated.
