Official Description

Suture of iris, ciliary body (separate procedure) with retrieval of suture through small incision (eg, McCannel suture)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 66682 involves the surgical suture of the iris and ciliary body, classified as a separate procedure. This technique is specifically utilized to address injuries or defects in these ocular structures. The process begins with the creation of a small incision in the conjunctiva, located at the limbus, which is the border between the cornea and the sclera, adjacent to the site of the injury. The use of suture material is integral to this procedure, as it is threaded through a needle that is strategically inserted at a point directly opposite the injury, ensuring proper alignment and tension during the repair. The needle traverses several anatomical layers, including the cornea, anterior chamber, iris base, iris root, and sclera, ultimately exiting at the injury site. This meticulous approach allows for several centimeters of suture to be pulled through the wound, with the suture material remaining attached to the needle for subsequent passes. The technique may involve a second pass through the iris root on the opposite side of the defect, facilitating a secure closure. The ends of the suture are then tied over the sclera, with the knot being buried to minimize irritation and promote healing. The conjunctival incision is subsequently closed, completing the procedure. This method of suture repair is often referred to as a McCannel double arm suture, highlighting its specific application in ocular surgery.

1. Indications

The procedure associated with CPT® Code 66682 is indicated for specific conditions affecting the iris and ciliary body. These indications include:

  • Trauma to the Iris or Ciliary Body - This procedure is performed to repair injuries resulting from trauma, which may compromise the integrity and function of these ocular structures.
  • Defects in the Iris - Surgical intervention is necessary for defects in the iris that may affect vision or lead to further complications.
  • Complications from Previous Eye Surgery - The procedure may be indicated in cases where previous surgical interventions have resulted in complications involving the iris or ciliary body.

2. Procedure

The procedure for CPT® Code 66682 involves several detailed steps to ensure effective suture repair of the iris and ciliary body. The steps are as follows:

  • Step 1: Incision Creation - A small incision is made in the conjunctiva at the limbus, which is the junction between the cornea and sclera, adjacent to the site of the iris injury. This incision provides access to the underlying structures that require repair.
  • Step 2: Needle Insertion - Suture material is threaded through a needle, which is then inserted at a point 180 degrees from the injury site in the iris. This positioning is crucial for achieving proper tension and alignment during the suture process.
  • Step 3: Passage Through Ocular Structures - The needle is passed through multiple layers, including the cornea, anterior chamber, iris base, iris root, and sclera, exiting at the site of the injury. This thorough passage ensures that the suture material effectively anchors the iris and ciliary body.
  • Step 4: Suture Retrieval - Several centimeters of suture are pulled through the wound, with the suture material remaining attached to the needle. This allows for the next steps of the procedure to be performed without losing the suture.
  • Step 5: Second Pass Through the Iris - The needle is retracted back into the anterior chamber, and a second pass is made through the iris root on the opposite side of the defect. This step is essential for creating a secure repair across the defect.
  • Step 6: Final Suture Placement - The needle and suture material are brought through the sclera a short distance from the first exit site. This positioning helps to secure the repair effectively.
  • Step 7: Knot Tying and Closure - The two ends of the suture material are tied over the sclera, and the knot is buried to minimize irritation to the surrounding tissues. Finally, the conjunctival incision is closed, completing the procedure.

3. Post-Procedure

Post-procedure care following the suture of the iris and ciliary body involves monitoring for any signs of complications, such as infection or improper healing. Patients may be advised to avoid strenuous activities and follow specific instructions regarding eye care to promote optimal recovery. Regular follow-up appointments are essential to assess the healing process and ensure that the repair is functioning as intended. Any prescribed medications, such as antibiotics or anti-inflammatory agents, should be taken as directed to support healing and prevent complications.

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).
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)
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.
