Can you please help me find the correct coding for the exploration of a left upper arm antecubital fossa? The physician tried to find a basilica vein to use for an AVF and was unable so this was strictly an exploration. Any help would be greatly appreciated.![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
