Ask Dr. Z

Hi Dr Z, The diagnoses in this case are incompetent lower extremity veins and bilateral LE venous malformations with pain and swelling. The GSV was treated with radiofrequency ablation. Then the physician says "Using direct stick technique, thrombectomy was performed on priviously sclerosed veins of bilateral lower extremities." This was followed by direct sclerotherapy on multiple veins of the right thigh. The questions is how do I code the "thrombectomies". Would 37187 be appropriate? Would it be coded twice for bilateral procedures? Thanks again.
