Reimbursement for Diagnostic Testing with the Topcon KR-1W Wavefront Analyzer (Topcon Medical Systems)

Topcon’s KR-1W Wavefront Analyzer has multiple capabilities. Topcon USA notes the following features for the instrument on their website:1

  • 5-in-1 instrument features wavefront aberrometry, corneal topography, keratometry, pupillometry, and autorefraction all in one unit
  • Multiple maps for overview analysis
  • Easy to operate with right/left fully automated measurement and touchscreen panel
  • Provides pre- and post-op data for cataract and refractive procedures2
  • Invisible light topographic measurement increases patient comfort
  • Fully networkable in various configurations

The measurement specifications for refractive range and corneal curvature are noted in Table 1. Information is displayed in many different ways. These include single-type maps (i.e., right/left, corneal, pupillometry, refraction) as well as multi-maps options which display multiple results in a single display. The instrument can output its data through multiple electronic transfer methodology; it is configured for USB, RS-232, or LAN.

This monograph describes reimbursement for in-office wavefront aberrometry, corneal topography, pupillometry, and auto-refraction with the Topcon KR-1W Wavefront Analyzer (Figure 1).

Much of the information in this document is taken from official publications of the Medicare program. The reader is encouraged to check with the local Medicare Administrative Contractor (MAC) for additional information and instructions. For 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-10-CM. Documentation of the tests performed with this instrument, as well as the medical necessity for them, are the key factors to supporting reimbursement, so we cover them in detail.

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