What 92313 covers

Code 92313 describes a clinician-directed fitting of a corneoscleral contact lens, which vaults the cornea and bears on the sclera. An ophthalmologist or optometrist typically evaluates the eye, selects and assesses trial lenses, and supervises adaptation. This approach is often considered for irregular corneas, such as with keratoconus or after corneal transplantation, and for some ocular-surface conditions. Fitting may include evaluating lens position and clearance, vision, comfort, and the patient’s ability to handle the lens.

Choose this code for the corneoscleral lens service, rather than a standard corneal lens fitting or a technician-performed fitting. Documentation should support the lens type, clinical fitting work, assessment of the trial lens, and the clinician’s supervision of adaptation. The contact lens product is distinct from the fitting service and should be handled separately when reportable. CMS valuation uses work and practice-expense inputs, with practice expense valued differently for office and facility settings.
