CPT® Code 69511

A mastoidectomy is a surgical procedure aimed at removing infected mastoid air cells, which are small, air-filled spaces located within the mastoid process, a bony structure situated behind the ear that projects from the temporal bone of the skull. The procedure is typically indicated in cases of acute infection, where the mastoid bone becomes compromised due to the presence of infection. During the surgery, an incision is made behind the ear to expose the mastoid bone, allowing the surgeon to access and remove the infected tissue. The radical mastoidectomy, specifically identified by CPT® Code 69511, is performed in cases of extensive cholesteatoma, a destructive and expanding growth that can lead to further complications if not addressed. This procedure involves the complete removal of the mastoid air cell system, along with any purulent matter and debris. Unlike a modified radical mastoidectomy, which preserves certain structures of the middle ear, a radical mastoidectomy entails the removal of additional anatomical components, including the head of the malleus and the body of the incus, and may also involve the stapes, although efforts are made to preserve it when possible. This extensive approach allows for the effective exteriorization of the mastoid cavity and middle ear, facilitating better drainage and management of the infection.
