I'am aware of the modifier xs-separate structure and
xu-unusual non-overlapping service. As coding spinal surgery it confusing with additional vertrbra such as l1, l2, l3 etc. Should it be coded xu or xs. Its the same structure but a difeerient level.thanks for your replies![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
