Official Description

Excision or transposition of pterygium; with graft

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 65426 involves the excision or transposition of a pterygium, which is a growth of conjunctival tissue that can extend onto the sclera and potentially invade the cornea. This condition is characterized by a raised, triangular appearance at the corner of the eye. The surgical intervention is necessary when the pterygium encroaches upon the central cornea, as it can lead to vision impairment and discomfort. In this specific procedure, the physician not only removes the pterygium but also addresses the resulting defect in the sclera by employing a graft. The excision is performed meticulously, ensuring that the pterygium is dissected down to the level of Tenon's capsule, which is a layer of tissue surrounding the eye. Following the removal of the pterygium, a graft is utilized to repair the defect left behind. This graft can be an autograft, taken from the patient's own conjunctiva, or an allograft, such as an amniotic membrane obtained from a tissue bank. The graft is then secured in place, either through suturing or the application of fibrin tissue glue, to promote healing and restore the integrity of the conjunctival surface.

1. Indications

The procedure described by CPT® Code 65426 is indicated for the surgical removal of a pterygium that has extended into the central cornea, causing potential vision impairment or discomfort. The following conditions may warrant this procedure:

  • Presence of Pterygium A raised, triangular growth of conjunctiva at the corner of the eye that extends onto the sclera and may invade the cornea.
  • Vision Impairment When the pterygium encroaches upon the central cornea, leading to visual disturbances.
  • Discomfort or Irritation Symptoms such as redness, irritation, or a foreign body sensation in the eye due to the pterygium.
  • Cosmetic Concerns Patients may seek surgical intervention for aesthetic reasons if the pterygium is prominent.

2. Procedure

The procedure for CPT® Code 65426 involves several critical steps to ensure the effective removal of the pterygium and the repair of the scleral defect:

  • Step 1: Anesthesia Administration The procedure begins with the administration of local anesthesia to ensure patient comfort during the surgery. This may involve the use of topical anesthetic drops applied to the eye.
  • Step 2: Excision of the Pterygium The surgeon carefully dissects the pterygium from the underlying scleral and corneal tissue. This step is crucial to ensure complete removal of the fibrous tissue that constitutes the pterygium, and it is performed down to the level of Tenon's capsule.
  • Step 3: Graft Harvesting Once the pterygium is excised, the next step involves harvesting a graft. An autograft, typically a free conjunctival graft, is obtained from the area under the eyelid of the patient. Alternatively, an allograft, such as an amniotic membrane graft, may be selected based on the clinical scenario.
  • Step 4: Graft Placement The harvested graft is then placed over the defect created by the excision of the pterygium. The graft is secured in place either by suturing it onto the conjunctiva or by using fibrin tissue glue, which helps to promote adherence and healing.
  • Step 5: Post-Operative Care After the graft is secured, the surgeon will provide instructions for post-operative care, which may include the use of antibiotic eye drops and follow-up appointments to monitor healing.

3. Post-Procedure

Following the procedure, patients can expect a recovery period during which they may experience some discomfort, redness, or swelling in the operated eye. It is essential to follow the post-operative care instructions provided by the physician, which may include the use of prescribed medications to prevent infection and manage pain. Patients are typically advised to avoid strenuous activities and to protect the eye from trauma during the healing process. Follow-up visits will be scheduled to assess the healing of the graft and the overall recovery of the eye.

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.)
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.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
