CPT® Code 67334

Add-On Code

1. Indications

The procedure associated with CPT® Code 67334 is indicated for the treatment of strabismus, which may manifest as misalignment of the eyes. The specific indications for performing strabismus surgery using the posterior fixation suture technique include:

• Strabismus A condition where the eyes do not properly align, leading to issues with binocular vision.
• Muscle Imbalance Situations where there is an imbalance in the extraocular muscles that requires surgical intervention to restore proper alignment.
• Need for Stabilization Cases where stabilization of the fixing eye is necessary to improve overall eye alignment and function.

2. Procedure

The procedure for CPT® Code 67334 involves several critical steps that ensure the successful application of the posterior fixation suture technique:

• Step 1: Exposure of the Eye Muscle The surgeon begins by performing a primary procedure that involves exposing the extraocular muscle. This step is essential as it allows access to the muscle that will be manipulated during the surgery.
• Step 2: Placement of Posterior Fixation Sutures Once the muscle is exposed, the surgeon places posterior fixation sutures through the borders of the extraocular muscle. This technique is designed to limit the action of the muscle or increase its workload without altering its primary position.
• Step 3: Specific Muscle Considerations Depending on which muscle is being addressed, specific techniques are employed. For the lateral rectus muscle, the inferior oblique insertion is dissected from the lateral rectus before placing the sutures. If the superior rectus muscle is involved, the fixation suture is placed behind the superior oblique muscle. In cases involving the inferior rectus muscle, both the inferior oblique and Lockwood's ligament are retracted to facilitate suture placement.
• Step 4: Completion of the Primary Procedure After the necessary sutures are placed, the primary procedure is completed, and the operative incisions are closed, ensuring that the surgical site is properly secured.

3. Post-Procedure

Post-procedure care following the application of CPT® Code 67334 involves monitoring the patient for any immediate complications and ensuring proper healing of the surgical site. Patients may be advised to follow specific postoperative instructions, which could include the use of prescribed eye drops to manage discomfort and prevent infection. Regular follow-up appointments are essential to assess the alignment of the eyes and the effectiveness of the surgery. The recovery period may vary depending on the individual patient's response to the procedure, and any concerns regarding vision or alignment should be promptly addressed by the healthcare provider.
