Ask Dr. Z

Dear Dr. Z: Via rt fem access catheter is placed into the lower abdominal aorta. Pelvic angiogram and left lower extremity angiogram was performed. Pelvic angiogram discusses right and left common femoral arteries, internal iliac arteries and right external iliac artery. Lt extremity angiogram discusses profunda femoris, superficial femoral, popliteal, anterior and posterior tibial funoff to the foot. Is it correct to assign 76716 for the angiography or must only 75710 be assigned since the right superficial femoral is not mentioned? SIR IR Coding Users' Guide, pg 293, Q24 indicates "The entire leg does not need to be imaged for the bilateral extremity angiography code (75716)to apply. One does not need to use reduced services modifier -52 if imaging is only done to the knees." Thank you. mlb
