Official Description

Maxillectomy; without orbital exenteration

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 31225 refers to a maxillectomy performed without orbital exenteration. A maxillectomy is a surgical procedure that involves the removal of the maxilla, which is the upper jawbone that also forms part of the orbit and the nasal cavity. This type of surgery is primarily indicated for patients with malignant tumors located in the maxillary sinus, which is the cavity situated within the maxilla. In cases where the tumor has invaded the periorbital region, a more extensive procedure known as orbital exenteration may be necessary; however, CPT® Code 31225 specifically denotes a maxillectomy that preserves the orbital structures. During the procedure, the surgeon gains access to the maxillary sinus through either a lateral rhinotomy, which is an incision made on the side of the nose, or an intraoral approach via the canine fossa, depending on the tumor's location. The surgical team meticulously resects both the mucosa and the bone of the maxillary sinus to ensure complete removal of the tumor. Following the resection, the orbital floor is reconstructed to maintain the structural integrity of the orbit. This procedure is critical for managing malignancies in the maxillary region while aiming to preserve surrounding anatomical structures, particularly the orbit, which houses the eye and its associated tissues.

1. Indications

The maxillectomy procedure described by CPT® Code 31225 is indicated for the following conditions:

  • Malignant Tumors of the Maxillary Sinus - This procedure is primarily performed to excise malignant tumors that have developed within the maxillary sinus, which may pose a risk to surrounding structures.

2. Procedure

The procedural steps for a maxillectomy without orbital exenteration are as follows:

  • Step 1: Patient Preparation - The patient is positioned appropriately, and anesthesia is administered to ensure comfort and pain management throughout the procedure.
  • Step 2: Surgical Access - The surgeon makes an incision either through a lateral rhinotomy or an intraoral approach via the canine fossa, depending on the specific location of the tumor within the maxillary sinus.
  • Step 3: Resection of Tumor - The mucosa and bone of the maxillary sinus are carefully resected to remove the tumor completely. This step is crucial to ensure that all malignant cells are excised.
  • Step 4: Orbital Floor Reconstruction - After the tumor has been removed, the orbital floor is reconstructed to maintain the structural integrity of the orbit and to support the surrounding tissues.

3. Post-Procedure

Post-procedure care for patients undergoing a maxillectomy without orbital exenteration typically includes monitoring for complications such as bleeding or infection. Patients may experience swelling and discomfort in the surgical area, which can be managed with pain relief medications. Follow-up appointments are essential to assess healing and to ensure that there are no signs of tumor recurrence. The surgical site will require proper care to promote healing and to minimize the risk of complications.

RT Right side (used to identify procedures performed on the right side of the body)
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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.)
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).
