Q5. Trabeculectomy with MMC was performed on a patient’s right eye. Subsequently, the patient suffered a wound leak and was fitted with a specially ordered bandage contact lens. CPT code 92071–RT is submitted for the fitting of the bandage lens. As the lens is not a covered benefit, the patient is billed for its supply. Unfortunately, the bandage lens didn’t work, so the conjunctiva is resutured at the slit lamp on postop day 30 in the dedicated office procedure room. What is the correct coding for the wound revision?

a) 66250–RT.

b) 66250–58–RT.

c) 66250–78–RT.

Q6. In the case of the trabeculectomy patient (Q5), resuturing doesn’t work, so revision of the bleb is performed in the ASC on postop day 60. How would you code for this?

a) 66250–58–RT.

b) 66250–76–RT.

c) 66250–78–RT.

Q7. A Trabectome procedure (CPT code 65850) is performed in the left eye. A postop hyphema requires a washout (CPT code 65815), which is performed in the operating room. What modifier should be appended to 65815?

a) –58.

b) –78.

c) –79.

Know Your Modifiers

The modifiers below indicate that “the same physician or other qualified health care professional” performs:

–58, a staged or related procedure or service during the postop period;

–76, a repeat procedure or service;

–78, a related procedure in an unplanned return to the operating/ procedure room following the initial procedure during the postop period; or

–79, an unrelated procedure or service during the postop period.

Use modifier –LT to indicate the left eye and –RT for the right.
