CPT® Code 67430

The procedure described by CPT® Code 67430 involves an orbitotomy, which is a surgical operation performed to access the orbit, the bony cavity that houses the eye. This specific procedure utilizes a lateral approach, meaning the incision is made on the side of the eye, allowing for direct access to the orbital contents. A bone flap or window is created during the surgery, which involves removing a section of bone to facilitate the exploration and treatment of the area. The primary goal of this procedure is to remove a foreign body that may have entered the orbit, which can cause pain, infection, or other complications. The operation begins with a lazy-S incision in the upper eyelid crease, which helps to minimize visible scarring. The lateral rectus muscle, one of the extraocular muscles responsible for eye movement, is then exposed and retracted to provide a clear view of the underlying structures. The surgeon carefully dissects through the soft tissues to reach the zygomatic bone, where the periosteum, a dense layer of connective tissue covering the bone, is incised. This allows for the drilling of holes and the creation of a bone window or flap, which is essential for accessing the orbit. Once the orbit is exposed, any foreign body present can be located and removed, ensuring that surrounding tissues are preserved as much as possible. After the removal of the foreign body, the surgical site is thoroughly cleaned, and the various layers of tissue, including the bone flap, are meticulously closed to promote proper healing.
