Official Description

Exenteration of orbit (does not include skin graft), removal of orbital contents; with therapeutic removal of bone

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Exenteration of the orbit is a surgical procedure primarily indicated for the removal of orbital tumors or intraocular tumors that have extended into the orbit or surrounding extraorbital structures, which may include the eyelids or the bony structures surrounding the eye. The procedure involves the complete removal of the contents of the orbit, which includes the eye itself and any associated tissues, while also addressing any underlying bony structures if necessary. The term 'exenteration' refers to the extensive nature of this surgery, which is performed to ensure that all diseased tissue is removed to prevent further complications or spread of malignancy. The procedure is complex and requires careful dissection and removal techniques to minimize damage to surrounding healthy tissues, particularly when the eyelid anatomy is intact. In cases where the eyelids are preserved, incisions are made strategically to allow for proper closure post-surgery. If the eyelids are completely excised, additional techniques such as skin grafting may be employed to facilitate closure of the surgical defect. This procedure is critical in managing severe orbital conditions and requires a thorough understanding of the anatomy and potential complications associated with the removal of orbital contents.

1. Indications

Exenteration of the orbit is performed for the following indications:

  • Orbital Tumors - The procedure is indicated for the presence of tumors located within the orbit that may threaten surrounding structures.
  • Intraocular Tumors - Tumors that extend from the eye into the orbit or extraorbital structures necessitate this surgical intervention.
  • Extension into Extraorbital Structures - Conditions where tumors invade adjacent structures such as the eyelids or the bony orbit require exenteration to ensure complete removal of malignant tissues.

2. Procedure

The procedure of exenteration of the orbit involves several critical steps:

  • Incision and Dissection - If the eyelid anatomy is free of disease, full-thickness incisions are made through the entire eyelid just above the upper lash line and just below the lower lash line. If only the skin of the eyelid is preserved, incisions are made through the skin at the same locations. The skin is then dissected from the underlying subcutaneous tissue, extending both superiorly and inferiorly to the level of the orbital rim.
  • Removal of Eyelids - In cases where the eyelids are completely removed, full-thickness incisions are made through the skin and soft tissue along the orbital rim. This allows for access to the orbital contents.
  • Dissection of the Periosteum - The periosteum of the orbital rim is dissected off the underlying bone in a circular fashion, ensuring that the entire globe and orbital contents are freed from their attachments.
  • Extraction of Orbital Contents - The entire globe and orbital contents are then removed carefully. This step is crucial to ensure that all diseased tissue is excised.
  • Inspection of Bony Structures - After the removal of the orbital contents, the underlying bony structures are inspected for any evidence of tumor extension. If tumor presence is detected in the bones of the orbit, bony tissue is excised accordingly.
  • Closure of the Surgical Site - If the eyelids or skin of the eyelids have been preserved, they are closed in layers. In cases where the eyelids have been completely excised, separately reportable skin grafts may be utilized to close the defect. The choice of closure technique depends on whether bone was removed during the procedure.
  • Use of Flaps - If muscle or myocutaneous flaps are required for closure, a free muscle or myocutaneous flap is developed, ensuring the preservation of blood supply to the flap. Commonly used free muscle flaps include the abdominis rectus or latissimus dorsi muscles. The flap is then trimmed to the desired size and shape, and blood vessels in the flap are sutured to surrounding blood vessels to ensure proper vascularization. The edges of the flap are secured with sutures to complete the closure.

3. Post-Procedure

Post-procedure care for patients undergoing exenteration of the orbit includes monitoring for complications such as infection, bleeding, and proper healing of the surgical site. Patients may require pain management and should be advised on signs of complications that necessitate immediate medical attention. Follow-up appointments are essential to assess the healing process and to ensure that there are no signs of tumor recurrence. If skin grafts or flaps were used, additional care may be needed to monitor the viability of the grafts and the integration of the flaps into the surrounding tissue.

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.
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.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, 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).
