I did not find any CCI Edits re: 15757 and 40845; 15757 is a free skin graft w/microvascular anostomies and 40845 is a vestibuloplasty that sometimes requires soft tissue grafting from another area;
was the free skin graft used for the vestibuloplasty??? if so, are you sure the skin graft required microvascular anostomies? or was it just a split or full thickness skin graft? Or, is the graft and vestibuloplasty totally separate? if so, Modifer XS would be appropriate.....need a little more info on this situation.
