While keratometry provides a measure of corneal curvature with special attention to asphericity and astigmatism, corneal topography (CT) provides the eye care professional with a precise map in minute detail of the configuration of the corneal surface. 

This monograph discusses reimbursement for CT.  Much of the information is taken from official publications of CMS and it’s Medicare Administrative Contractors (MACs); however, the reader is encouraged to check with the local MAC for additional information and instructions.  In the case of other third party payers, we have used the coding concepts contained in CPT and published by the American Medical Association; diagnosis codes are from ICD-9-CM.  Documentation of the procedure is a key part of reimbursement, so we describe the required elements in detail. 

Since economic analyses are a necessary part of any capital budgeting decision, we incorporated Medicare’s utilization and payment rates for the test.
