I have scoured the internet to find anything about this procedure. I usually slip it in with other destruction of lesion(s) anus: ei… Condyloma, Papilloma, Mulluscum contagiosum, Herpetic vesicle
as my providers usually do a combination of surgical excision 46922, electrocautery 46910, or multi approaches to extensive lesions. CPT-46924
but my last op report us solely using CUSA only.

" I did commence my procedure here using the CUSA device to remove the top few layers of skin down to good healthy tissue. I did this in a continuous anner all across the posterior portion of the perineal body. Operating anoscope was inserted. I was able to appreciate changes up to the midline in the anterior midline. I then took approximately 1/3 of the circumference of the anal canal and using CUSA removed the abnormal tissue in the anterior midline. I did not need to remove anything from the lateral locations or the posterior location. Hemostasis was achieved. Perineal body was further inspected. I did a little bit more work anteriorly in one small area near her right labia. All this was sent a CUSA aspirate"
