Reader Question:

Corneal Topography

Published on Mon Oct 01, 2001

Question: How should we bill for corneal topography?
Colorado Subscriber  
Answer: There is no code for corneal topography, but  you may bill for the procedure using the unlisted-procedure code 92499 (unlisted ophthalmological service or procedure). In the comments field, indicate exactly what you did (corneal topography). You can bill for corneal topography done for surgically induced astigmatism or for a corneal transplant.
 
Some Medicare carriers consider astigmatism (367.20) justification for corneal topography, but most require it to be in combination with a postsurgical condition or a corneal transplant. The easiest way to ensure that you will be reimbursed is to file the claim on paper and submit your interpretation and the topography.
