Can anyone help guide me in the right direction on coding this. He made a post auricular incision in the mastoid cavity and performed a mastiodectomy, after that he states " attention was turned towards the lateral semi circular canal and superior semi circular canal. The superior semi circular canal was drilled which led to the exposure of a dehiscent area in the semi circular canal. The dura was dissected off and a pocket was created between the tegmen and the dura posterior and medial to the superior semi circular canal. Once this was done, I noted that a lot of tegmen bone was taken out opening up the areas of dura. I note that a piece of cortical bone was harvested from the temporal bone and in a split calvarial graft type fashion, this piece was bone was wedged on top of the superior semi circular canal to reconstruct this area." I am coding a 69641 but i have no idea what to use for the dehiscence repair. Any help would be appreciated.

As there is no specific code for this type of scenario please use the unlisted procedure inner ear code 69949.


Hope this helps!
