Ask Dr. Z

DR. Z, The patient came in for AV fistula creation and in the same setting it states 'using ultrasound, the upper extremity was mapped. Based on the findings from the ultrasound decision was made to proceed with a left basilic vein transposition.' Not sure if this is good enough to code 'G0365'along with the creation of AV fistula? Is this ultrasound mapping included in the AV fistula performed in the same setting? Sometimes we see an order stating vein mapping or pre op for AV fistula creation and the procedure is bilateral venogram, please clarify when and what kind of documentation suports 'G0365'? Thanks
