Reader Question:

Avoid Unlisted for Corneal Topography

Question: We have a new physician who performs corneal topography, which our practice has never done before. Our office manager said to report the unlisted code for this service. Is that correct?

Answer: You are correct to be suspicious of using unlisted code 92499 (Unlisted ophthalmological service or procedure) for this service, because CPT® does include a dedicated code for corneal topography, which is 92025 (Computerized corneal topography, unilateral or bilateral, with interpretation and report). The doctor may also refer to this service as “corneal mapping.”

Because the code descriptor specifies unilateral or bilateral, you should report the code just once even if the doctor performs the service on both eyes, and no modifier will be necessary.
