Official Description

Closure of lacrimal fistula (separate procedure)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 68770 refers to the closure of a lacrimal fistula, which is classified as a separate procedure. A lacrimal fistula is an abnormal connection or passageway that forms between the lacrimal system and the skin, allowing tears or other fluids to drain externally. These fistulas can be either congenital, meaning they are present at birth, or acquired, which may occur due to trauma or disease processes such as infections. Congenital fistulas can be categorized into open and closed types. Open fistulous tracts are characterized by a visible small hole located inferior to the medial canthus, where tears or other fluids can leak onto the skin. In contrast, closed fistulous tracts terminate in a blind sac and do not exhibit any drainage. The closure of a lacrimal fistula typically involves the administration of a local anesthetic to ensure patient comfort during the procedure. Following anesthesia, the fistulous tract is carefully inspected, and the closure is achieved through techniques such as electrocautery or laser surgery, among other methods. This procedure aims to restore normal drainage of tears and prevent any further complications associated with the fistula.

1. Indications

The closure of a lacrimal fistula, as indicated by CPT® Code 68770, is performed for specific conditions related to the presence of a lacrimal fistula. The following are the indications for this procedure:

  • Congenital Lacrimal Fistula - This includes both open and closed types, where the fistula is present from birth and may require closure to prevent drainage issues.
  • Acquired Lacrimal Fistula - These fistulas may develop due to trauma or disease, such as infections, necessitating closure to restore normal function and prevent complications.
  • Drainage Issues - Patients experiencing abnormal drainage of tears or fluids onto the skin due to the presence of a fistula may require this procedure to correct the issue.

2. Procedure

The procedure for the closure of a lacrimal fistula involves several key steps, which are outlined as follows:

  • Step 1: Administration of Local Anesthetic - The procedure begins with the administration of a local anesthetic to the patient. This is crucial for ensuring that the patient remains comfortable and pain-free during the intervention.
  • Step 2: Inspection of the Fistulous Tract - Once the anesthetic has taken effect, the surgeon inspects the fistulous tract. This step is essential for assessing the extent of the fistula and determining the most appropriate method for closure.
  • Step 3: Closure of the Fistula - The actual closure of the lacrimal fistula is performed using techniques such as electrocautery or laser surgery. These methods are employed to obliterate the fistulous tract effectively, ensuring that it no longer drains fluid externally.

3. Post-Procedure

After the closure of the lacrimal fistula, patients may require specific post-procedure care to ensure proper healing and recovery. This may include monitoring for any signs of infection, managing discomfort, and following up with the healthcare provider to assess the success of the procedure. Patients are typically advised on any restrictions regarding activities and may be given instructions on how to care for the surgical site to promote optimal healing.

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).
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.)
