CPT guidelines
For an accurate response to your surgical coding question, please post the scrubbed op note.
I do not know if your codes are correct without seeing the operative note... however ...
CPT guidelines (2011 Professional Edition, pg 73) state: A repair of a donor site requiring a skin graft or local flaps is considered an additional separate procedure.
Hope that helps.
