CPT® Code 69603

A revision mastoidectomy is a surgical procedure aimed at addressing complications arising from previous mastoid surgeries, specifically to remove infected mastoid air cells. The mastoid process, which is a bony structure located behind the ear, is an extension of the temporal bone of the skull. Within this bony area, there are numerous mastoid air cells that can become infected, leading to various ear-related health issues. During the procedure, a surgical incision is made behind the ear to expose the mastoid bone. The surgeon then inspects the remaining mastoid air cells to assess the extent of the infection and determine the necessary surgical intervention. In the context of CPT® Code 69603, the revision mastoidectomy results in a radical mastoidectomy, which is indicated for cases involving recurrent extensive cholesteatoma. This procedure involves the complete removal of the mastoid air cell system, along with any purulent matter, debris, and infected tissue. The surgical approach is similar to that of a modified radical mastoidectomy, but it also includes the removal of critical structures within the epitympanum, such as the head of the malleus and the body of the incus, which are essential components of the middle ear. The stapes may also be removed during this procedure, although efforts are made to preserve it when possible. This comprehensive approach allows for the effective exteriorization of the mastoid cavity and the middle ear, facilitating better management of the underlying condition.
