Official Description

Nasal/sinus endoscopy, surgical; with dacryocystorhinostomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 31239 refers to a surgical nasal and sinus endoscopy that includes a dacryocystorhinostomy. This surgical intervention is primarily indicated for patients experiencing a blockage in the nasolacrimal duct, which impedes the normal flow of tears. The goal of the procedure is to restore this flow by creating a new canal for tear drainage. During the operation, a topical nasal decongestant may be applied to reduce swelling and facilitate access to the nasal passages. Additionally, a local anesthetic with a vasoconstrictor is utilized to minimize discomfort and control bleeding during the procedure. The use of a fiberoptic light probe allows the surgeon to visualize the lacrimal sac through the canaliculus, which is the small duct that carries tears from the eye to the nasal cavity. The endoscopic approach enables the surgeon to navigate the nasal anatomy effectively, ensuring precise removal of tissue and bone to create a new pathway for tear drainage. This procedure is essential for alleviating symptoms associated with tear duct obstruction, such as excessive tearing or recurrent infections, thereby improving the patient's quality of life.

1. Indications

The procedure is indicated for the following conditions:

  • Blocked Nasolacrimal Duct - This condition leads to impaired tear drainage, resulting in excessive tearing or chronic infections.
  • Chronic Dacryocystitis - Inflammation of the lacrimal sac due to obstruction can necessitate surgical intervention to restore normal function.
  • Recurrent Eye Infections - Frequent infections may occur as a result of tear duct blockage, prompting the need for dacryocystorhinostomy.

2. Procedure

The surgical procedure involves several critical steps to ensure successful creation of a new tear duct canal:

  • Preparation - The patient is prepared for the procedure with the application of a topical nasal decongestant to reduce nasal swelling and a local anesthetic with a vasoconstrictor to minimize discomfort and control bleeding during the surgery.
  • Introduction of Fiberoptic Light Probe - A fiberoptic light probe is carefully introduced through either the upper or lower canaliculus and advanced into the lacrimal sac, allowing visualization of the area.
  • Endoscope Insertion - An endoscope is then introduced through the nasal cavity, enabling the surgeon to locate the light probe on the lateral wall of the nose, which is crucial for guiding the subsequent steps.
  • Mucosal Removal - A small circle of mucosa is excised at the site identified through transillumination, exposing the underlying bone necessary for the procedure.
  • Bone Access - To gain access to the bone beneath the mucosa, a portion of the uncinate process may be removed. This is accomplished using a drill or YAG laser to ensure precision.
  • Probe Replacement - The light probe is then removed and replaced with a metal probe, which aids in the next steps of the procedure.
  • Lacrimal Sac Opening - The medial wall of the lacrimal sac is tented and opened using cutting forceps, with the opening being enlarged to approximately 1 cm to facilitate drainage.
  • Stent Insertion - Stents attached to silastic tubing are inserted through the upper and lower canaliculi. The stent is then passed into the nasal cavity, where it is removed from the tubing and secured, forming a continuous loop around the canaliculi to maintain the newly created pathway.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any complications and ensuring proper healing of the surgical site. Patients may be advised on the use of saline nasal sprays to keep the nasal passages moist and to prevent crusting. Follow-up appointments are essential to assess the success of the procedure and to remove any stents if necessary. Patients should be informed about signs of infection or other complications that may require immediate medical attention.

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).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
55 Postoperative management only: when 1 physician or other qualified health care professional performed the postoperative management and another performed the surgical procedure, the postoperative component may be identified by adding modifier 55 to the usual procedure number.
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.
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.
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).
