Our hand specialist performed an excision of ganglion cysts on one wrist, both volar and dorsal. CPT code 25111 is excision of ganglion cyst, dorsal or volar. If the surgeon did two separate incisions, can he bill 25111 twice? All the edits say that you can only bill it once, but how do you bill to indicate that you did more than one cyst. The problem is that there are no codes that distinguish between dorsal and volar cyst, so you would be using the same diagnosis, M67.341. Does anyone have any other suggestions on how to bill this? It would be helpful to know since this procedure seems to be common. Thank you.
