Ask Dr. Z

Dr.Z, Question for AV graft creation. Hand venogram performed and peripheral veins looked fine howver central venogram demonstrated extensive collateralization around the left subclavian and innominate veins. The decision was made to proceed with a left subclavian and innominate veins prior to creation of an AV fistula. The post op diagnosis states left subclavian and innominate vein stenosis. After PTA performed creation of left upper extremity b rachiobasillic AV fistula. My question can we charge PTA separate from the creation or it is part of the creation. If we can charge PTA can we charge two or one PTA? Thanks
