Official Description

Ethmoidectomy; extranasal, total

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An extranasal total ethmoidectomy, designated by CPT® Code 31205, is a surgical procedure aimed at addressing issues within the ethmoid sinus. This procedure is characterized by its approach through a lateral rhinotomy, which entails making an incision along the side of the nose. This incision allows the surgeon to access the ethmoid sinus by drilling through the bone, thereby reaching both the anterior and posterior ethmoid cells. During the procedure, the surgeon inspects the ethmoid cells for any pathological conditions, such as the presence of purulent material or mucoceles, which are fluid-filled sacs that can develop due to blockage or infection. The surgical intervention includes the evacuation of this purulent material and the removal (ablation) of the mucosa down to the underlying bone, ensuring that any diseased tissue is thoroughly addressed. In cases where the ethmoid ostium, the natural opening of the ethmoid sinus into the nasal cavity, is obstructed, the surgeon will create an additional opening to facilitate proper drainage of fluid from the ethmoid cells. This comprehensive approach aims to restore normal function and alleviate symptoms associated with ethmoid sinus conditions.

1. Indications

The extranasal total ethmoidectomy is indicated for various conditions affecting the ethmoid sinus. These indications include:

  • Chronic Sinusitis Persistent inflammation of the sinus cavities that does not respond to medical management.
  • Ethmoid Cell Disease Pathological conditions specifically affecting the ethmoid cells, which may include infection or obstruction.
  • Mucoceles Fluid-filled sacs that can develop in the ethmoid sinus, often requiring surgical intervention for drainage.
  • Obstructive Conditions Situations where the natural drainage pathways of the ethmoid sinus are blocked, necessitating surgical correction.

2. Procedure

The procedure for an extranasal total ethmoidectomy involves several critical steps, each designed to ensure effective access and treatment of the ethmoid sinus. The steps include:

  • Step 1: Lateral Rhinotomy The surgeon begins by making an incision along the side of the nose, which is referred to as a lateral rhinotomy. This incision provides the necessary access to the ethmoid sinus.
  • Step 2: Bone Drilling Following the incision, the surgeon drills through the bone to reach the anterior and posterior ethmoid cells. This step is crucial for gaining access to the areas that require treatment.
  • Step 3: Inspection of Ethmoid Cells Once access is achieved, the surgeon inspects the ethmoid cells for any signs of infection, obstruction, or other pathological conditions. This inspection is vital for determining the extent of the disease.
  • Step 4: Evacuation of Purulent Material If purulent material or mucoceles are identified, the surgeon proceeds to evacuate this material to alleviate symptoms and prevent further complications.
  • Step 5: Mucosa Ablation The next step involves the removal (ablation) of the mucosa down to the bone. This ensures that any diseased tissue is thoroughly addressed, promoting healing and recovery.
  • Step 6: Creation of Ethmoid Ostium Opening If the ethmoid ostium is found to be obstructed, the surgeon creates an opening into the nasal cavity. This step is essential for facilitating proper drainage of fluid from the ethmoid cells, thereby restoring normal sinus function.

3. Post-Procedure

After the extranasal total ethmoidectomy, patients can expect a recovery period that may involve monitoring for any signs of complications, such as infection or excessive bleeding. Post-operative care typically includes pain management and instructions for nasal care to promote healing. Patients may also be advised on the importance of follow-up appointments to assess the success of the procedure and ensure that the ethmoid sinus is functioning properly. It is essential for patients to adhere to their healthcare provider's recommendations during the recovery phase to optimize outcomes.

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.
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).
