CPT code 92310: Contact lens fitting, both eyes; non-aphakic2026 Medicare rate & RVUs

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

What 92310 covers

This service covers selecting the optical and physical characteristics of corneal contact lenses and fitting them on both eyes, with clinical supervision of the patient’s adaptation. Optometrists and ophthalmologists commonly perform or report the fitting for patients using contact lenses to correct refractive errors such as myopia, hyperopia, or astigmatism. The code is for patients who are not aphakic and does not describe fitting a corneoscleral lens.

For Medicare, status N means this service is not covered. The code is in the CPT Category I code set, and it represents a bilateral fitting rather than a charge per lens or per eye. Aphakia fittings and technician-performed fittings have separate codes, so the clinical circumstances and who performs the fitting distinguish those services.
