Question:
I did an anterior and posterior spine procedure on the same day. I used local bone graft (20936) and morselized allograft (20930) on the anterior and posterior procedures. Should I bill 20930, 20930-59, 20936, 20936-59 or 20930 x 2 units with 20936 x 2 units?

Answer:
Actually, neither. CPT guidelines say to bill the applicable bone graft code(s) only once per operative session.
