Using modifier 58 vs 78.
Initial surgery was 35355(Thromboendarterectomy) & 35566 (fem-tib vein bypass graft). Pt comes back to OR for large area of debridement's almost weekly due to an skin infection. For all the debridement surgeries would you code them with a 58 or a 78 attached due to the initial surgery which has a 90global? The notes do not state anything was planned about taking the patient back to OR for any of these services so they were unplanned. One opinion is that 58 is "related/extensive" so it should be used but since this technically isn't on same location or initial problem (vessels) so thoughts are to use modifier 78. Any recommendations?
