Nope you're still in the wrong body part section. That is listed under the subtitle (in red letters) for Pharynx, Adenoid, and Tonsils. The mention of "Hard Palate" should lead your search.
In the index, follow this trail (stick with me, it's all a process!)
Palate - Repair - listed under this is Cleft, Laceration, Vomer, and the Unlisted code. There is no code listed for "hemorrhage control" so head for the first listing so you can read through the options. (code 42180; pg 306)
With cautery of excision site as the method used, there is no exact code in this section describing this. So you're left with the unlisted code under "Other Procedures"
I even looked for something for cautery of surgical wound on mucous membrane of palate or mouth and found nothing I would rather use than the "other".
Another thing to consider: although this was a different surgeon, were both surgeons in the same physician's group? If yes, this could be considered part of the global care fee for this procedure and the care rendered bundled with the surgical fee.
I am not an experienced coder but it is very important you know what body part you are reading about to narrow down where the work is being done and let that guide you to the correct coding section. It's like following a map - one wrong turn and you find yourself in Timbuktoo! Keep smiling!
