Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 92025 covers

Computerized corneal topography captures and analyzes corneal surface shape to produce a curvature map, helping identify steepening or irregularity that may not be evident from routine examination alone. Ophthalmologists and optometrists commonly use it when evaluating suspected keratoconus or irregular astigmatism, or when planning corneal or refractive treatment and contact lens management. The test is performed with a dedicated imaging device in an eye-care office or facility, with the clinician interpreting the resulting map in the context of the examination.

Report the service when the topographic study is performed and interpreted; retain the clinical reason for testing and the findings or interpretation in the record. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. The code is priced for both eyes, so modifier 50 does not increase payment. When multiple ophthalmic diagnostic procedures are performed, the multiple-procedure reduction applies to the technical component.

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
