CPT® Code 66605

1. Indications

The procedure described by CPT® Code 66605 is indicated for specific conditions affecting the iris and ciliary body. The following are the explicitly provided indications for performing this procedure:

• Lesion on the Iris The primary indication for an iridectomy is the presence of a lesion on the iris that requires removal to prevent complications or further issues.
• Lesion on the Ciliary Body A cyclectomy may be indicated when there is a lesion on the ciliary body that necessitates excision to address potential health concerns.

2. Procedure

The procedure for CPT® Code 66605 involves several critical steps that ensure the effective removal of the targeted lesions while minimizing trauma to surrounding tissues. The following procedural steps are outlined:

• Step 1: Anesthesia Application The physician begins by applying a local anesthetic to the eye to ensure that the patient remains comfortable and experiences minimal pain during the procedure. This step is crucial for patient safety and comfort.
• Step 2: Incision Creation An incision is then made in the cornea or at the limbus of the sclera. This incision provides access to the iris and ciliary body, allowing the physician to perform the necessary excisions. The choice of incision location is determined based on the specific anatomy and the location of the lesion.
• Step 3: Lesion Excision The physician proceeds to excise the lesion located on the iris, ensuring that a margin of healthy tissue is included in the excision. This step is critical to ensure complete removal of the lesion and to reduce the risk of recurrence.
• Step 4: Cyclectomy In conjunction with the iridectomy, the physician performs a cyclectomy, which involves the removal of a portion of the ciliary body. This step is essential when a lesion is present on the ciliary body, as it allows for the complete excision of the affected tissue.

3. Post-Procedure

After the completion of the iridectomy with cyclectomy, the patient will require specific post-procedure care to ensure proper healing and recovery. The physician will typically provide instructions regarding the care of the eye, which may include the use of prescribed eye drops to prevent infection and reduce inflammation. Patients are often advised to avoid strenuous activities and to protect the eye from potential trauma during the initial recovery period. Follow-up appointments will be necessary to monitor the healing process and to assess the success of the procedure. Any signs of complications, such as increased pain, redness, or vision changes, should be reported to the physician immediately for further evaluation.
