The procedure described by CPT® Code 67420 involves an orbitotomy, which is a surgical intervention performed to access the orbit, the bony cavity that contains the eye. This specific approach is lateral, meaning that the incision is made on the side of the eye, allowing for direct access to the orbital contents. The procedure includes the creation of a bone flap or window, which is a section of bone that is temporarily removed to facilitate the exploration and treatment of the orbit. During this surgery, definitive actions such as the removal of a lesion or foreign body are performed. The common language description highlights the meticulous steps involved, starting with a lazy-S incision in the upper eyelid crease, which is designed to minimize visible scarring. The lateral rectus muscle, one of the extraocular muscles, is exposed and retracted to provide a clear view of the underlying structures. The surgical team dissects through the soft tissues to expose the zygomatic bone, which is part of the facial skeleton. The periosteum, a dense layer of connective tissue covering the bone, is incised to allow access to the hard cortical bone of the zygoma. Holes are drilled into the bone, which are then connected using an oscillating saw to create a bone window or flap. This technique is crucial for gaining access to the orbit without causing excessive damage to surrounding tissues. Once the periorbita, the fibrous tissue surrounding the orbit, is incised, the surgeon carefully dissects the underlying fat and soft tissue attachments to fully expose the orbit. In the context of CPT® Code 67420, the primary focus is on the removal of a lesion, which can be either cystic or solid and may involve soft tissue and/or bony structures. The lesion is meticulously dissected free from surrounding tissues, ensuring that all abnormal tissue is removed along with a margin of normal tissue to minimize the risk of recurrence. The excised lesion is then sent for pathology evaluation to determine its nature. The procedure may also involve the removal of foreign bodies, as indicated by CPT® Code 67430, where the foreign object is either grasped with forceps or carefully dissected from surrounding tissues. After the lesion or foreign body is removed, the surgical site is flushed with sterile saline or an antibiotic solution as necessary. The final steps involve reapproximating the orbital tissues, closing the periorbita, replacing and securing the bone window or flap with miniplates and screws, and closing the soft tissues and skin of the eyelid in layers to ensure proper healing and aesthetic outcomes.

The procedure described by CPT® Code 67420 is indicated for various conditions affecting the orbit, particularly when there is a need to access and remove lesions or foreign bodies. The following are specific indications for performing an orbitotomy with a lateral approach:
The procedure for CPT® Code 67420 involves several detailed steps to ensure effective access and treatment of the orbital contents. The following outlines the procedural steps:
After the completion of the orbitotomy procedure, patients can expect specific post-operative care and considerations. The surgical site will require monitoring for signs of infection, swelling, or complications. Patients may be advised to avoid strenuous activities and to keep the head elevated to reduce swelling. Pain management may be necessary, and the use of prescribed medications should be followed as directed. Follow-up appointments will be essential to assess healing and to review pathology results from the excised lesion. The surgeon will provide specific instructions regarding wound care and any restrictions on activities to ensure proper recovery.

| 50 | Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 62 | Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate. | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | 80 | Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s). | 82 | Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s). | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | E1 | Upper left, eyelid | E4 | Lower right, eyelid | GC | This service has been performed in part by a resident under the direction of a teaching physician | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | SG | Ambulatory surgical center (asc) facility service |
