Official Description

Sinusotomy frontal; obliterative, without osteoplastic flap, coronal incision (includes ablation)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Obliterative frontal sinusotomy, as described by CPT® Code 31081, is a surgical procedure aimed at addressing issues related to the frontal sinus, particularly in cases where other treatments have failed. This procedure is less commonly performed today but may still be indicated for patients suffering from intractable frontal sinusitis, complications arising from previous surgical interventions, or conditions such as mucopyocele. The technique involves a coronal incision, which is made along the hairline, allowing access to the frontal sinus without the use of an osteoplastic flap. The primary goal of this surgery is to obliterate the frontal sinus, effectively preventing the recurrence of sinus-related issues by removing the sinus mucosa and filling the sinus cavity with abdominal fat. This approach is particularly relevant for patients who have not responded to endoscopic treatments or have experienced late complications from prior open obliteration procedures. The procedure includes the use of a burr to access the sinus and the complete ablation of the mucosa, ensuring that the sinus is thoroughly treated to mitigate future problems.

1. Indications

The obliterative frontal sinusotomy procedure, coded as CPT® 31081, is indicated for specific conditions and scenarios where other treatment options have proven ineffective. The following are the explicitly provided indications for this procedure:

  • Intractable Frontal Sinusitis - This condition involves persistent inflammation of the frontal sinus that does not respond to standard medical or surgical treatments.
  • Failed Endoscopic Treatment - Patients who have undergone endoscopic procedures for frontal sinus issues but have not achieved the desired results may require this surgical intervention.
  • Mucopyocele - This refers to a cystic lesion filled with mucus and pus that can develop in the frontal sinus, necessitating surgical intervention for resolution.
  • Late Complications of Previous Open Obliteration Procedures - Patients who have previously undergone open obliteration of the frontal sinus and are experiencing complications may benefit from this procedure.
  • Failed Open Obliteration - If prior attempts to obliterate the frontal sinus through open surgery have not succeeded, this procedure may be indicated.

2. Procedure

The obliterative frontal sinusotomy procedure involves several critical steps to ensure effective treatment of the frontal sinus. The following procedural steps are outlined:

  • Step 1: Incision - A coronal incision is made along the hairline, providing access to the frontal sinus. This incision is strategically placed to minimize visible scarring while allowing adequate exposure for the surgical procedure.
  • Step 2: Accessing the Frontal Sinus - A burr is utilized to access the medial aspect of the upper wall of the frontal sinus. This step is crucial for creating an opening that allows the surgeon to perform the necessary interventions within the sinus cavity.
  • Step 3: Ablation of Mucosa - The frontal sinus mucosa is elevated and completely removed using a drill, often with the assistance of an endoscope. This thorough ablation is essential to eliminate any diseased tissue and prevent future complications.
  • Step 4: Plugging the Frontal Sinus Ostium - Once the mucosa has been fully ablated, the frontal sinus ostium is plugged with cellulose or another suitable material. This step is vital for ensuring that the sinus remains closed off from the nasal cavity.
  • Step 5: Obliteration of the Sinus - The final step involves filling the sinus cavity with abdominal fat, effectively obliterating the sinus and preventing any recurrence of sinus-related issues.

3. Post-Procedure

After the obliterative frontal sinusotomy procedure, patients can expect a recovery period that may involve specific post-operative care. It is essential to monitor for any signs of complications, such as infection or excessive bleeding. Patients may be advised to avoid strenuous activities and follow up with their healthcare provider for assessments of healing and any necessary interventions. Pain management and instructions for wound care will also be provided to ensure a smooth recovery process. The overall goal of post-procedure care is to facilitate healing and prevent any recurrence of the conditions that necessitated the surgery.

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).
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.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
CR Catastrophe/disaster related
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)
XU Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service
