Official Description

Nasal/sinus endoscopy, surgical, with frontal sinus exploration, including removal of tissue from frontal sinus, when performed

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A surgical nasal/sinus endoscopy is a minimally invasive procedure that allows for direct visualization and intervention within the nasal cavity and paranasal sinuses. This specific procedure, identified by CPT® Code 31276, involves a detailed exploration of the frontal sinus, which is one of the key paranasal sinuses located in the forehead region. During this endoscopic procedure, a topical nasal decongestant may be applied to reduce swelling and facilitate easier access to the nasal passages. Additionally, a local anesthetic with a vasoconstrictor is often utilized to minimize discomfort and control bleeding during the surgery. An endoscope, a thin, flexible tube equipped with a camera and light source, is carefully introduced through the nostril to provide a clear view of the nasal cavity and surrounding structures. The surgeon inspects the nasal cavity and the paranasal sinuses for any signs of disease or abnormalities, such as polyps, infections, or blockages. The procedure includes the opening of the superior and anterior ethmoid air cells in the frontal recess, which is crucial for ensuring proper drainage and ventilation of the frontal sinus. The nasofrontal duct or ostium, which connects the frontal sinus to the nasal cavity, is also cleared of any obstructions that may impede sinus drainage. Once access to the frontal sinus is achieved, curved forceps are utilized to explore the sinus cavity, allowing for the removal of any diseased or infected tissue as necessary. This comprehensive approach not only aids in diagnosing sinus conditions but also provides therapeutic intervention to alleviate symptoms and improve sinus function.

1. Indications

The surgical nasal/sinus endoscopy with frontal sinus exploration, as described by CPT® Code 31276, is indicated for various conditions affecting the nasal and sinus cavities. The following are explicitly provided indications for this procedure:

  • Chronic Sinusitis - Persistent inflammation of the sinuses that does not respond to medical management.
  • Frontal Sinus Disease - Conditions affecting the frontal sinus, including infections or blockages.
  • Sinus Polyps - Growths within the nasal passages or sinuses that can obstruct airflow and drainage.
  • Sinus Tumors - Abnormal growths that may require removal for diagnosis or treatment.
  • Recurrent Acute Sinusitis - Frequent episodes of acute sinus infections that may necessitate surgical intervention.

2. Procedure

The procedure for CPT® Code 31276 involves several critical steps to ensure effective exploration and treatment of the frontal sinus. The following procedural steps are outlined:

  • Step 1: Preparation - Prior to the procedure, a topical nasal decongestant is applied to the nasal mucosa to reduce swelling and facilitate access. A local anesthetic with a vasoconstrictor is also administered to minimize discomfort and control bleeding during the procedure.
  • Step 2: Introduction of the Endoscope - An endoscope, which is a thin, flexible tube equipped with a camera and light source, is carefully introduced through the nostril. This allows the surgeon to visualize the nasal cavity and paranasal sinuses in real-time.
  • Step 3: Inspection of the Nasal Cavity - The surgeon inspects the nasal cavity and the paranasal sinuses for any signs of disease or abnormalities, such as polyps, infections, or structural issues that may affect sinus drainage.
  • Step 4: Opening of Ethmoid Air Cells - The superior and anterior ethmoid air cells in the frontal recess are opened to improve drainage and ventilation of the frontal sinus.
  • Step 5: Clearing the Nasofrontal Duct - The nasofrontal duct or ostium is cleared of any obstructions that may impede the drainage of the frontal sinus, ensuring proper sinus function.
  • Step 6: Exploration of the Frontal Sinus - Once access to the frontal sinus is achieved, curved forceps are employed to explore the sinus cavity. This step allows the surgeon to assess the condition of the sinus and identify any diseased or infected tissue.
  • Step 7: Removal of Diseased Tissue - Any diseased or infected tissue within the frontal sinus is removed as necessary to alleviate symptoms and restore normal sinus function.

3. Post-Procedure

After the completion of the surgical nasal/sinus endoscopy with frontal sinus exploration, patients may experience some discomfort and nasal congestion as part of the recovery process. It is important for patients to follow post-operative care instructions provided by their healthcare provider, which may include the use of saline nasal sprays to keep the nasal passages moist and promote healing. Patients are typically advised to avoid strenuous activities and heavy lifting for a specified period to prevent complications. Follow-up appointments may be scheduled to monitor healing and assess the success of the procedure. Any signs of infection, increased pain, or unusual symptoms should be reported to the healthcare provider promptly for further evaluation.

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).
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).
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)
GC This service has been performed in part by a resident under the direction of a teaching physician

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.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.
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.
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).
