In regards to CPT 28305, my provider wants to know if the autograft can be locally harvested or does he have to make a separate incision distant from the area for the autograft to count?

The Coder’s Desk Reference states, "Report 28305 when a bone graft is necessary. For this procedure, the physician debrides the intended graft recipient site of the tarsal and a bone graft from the iliac crest or other site is shaped and placed between the prepared surfaces."

So am I correct in thinking that based on the Coder’s Desk Reference that the autograft can’t be locally harvested and has to be harvested from a different area?

Thanks in advance.
