CPT code 92283: Color vision exam, extended testing2026 Medicare rate & RVUs

Medicare pays $55.11 for 92283 nationally in the office. Local office rates run $47.91–$76.98.

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

What 92283 covers

An extended color vision examination evaluates how a patient distinguishes colors using methods such as hue-arrangement testing or an anomaloscope. Ophthalmologists and optometrists may use it to characterize a suspected color-vision deficiency or investigate acquired color-perception changes, including in an ophthalmology or optometry office. The extended testing provides more detail than a basic color-plate examination.

Choose 92283 when the service includes extended testing and interpretation, rather than a simpler color vision examination. Documentation should identify the test method, findings, clinical interpretation, and reason for testing. The code has separately priced professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no modifier represents the global service. The ophthalmology diagnostic multiple procedure reduction applies to the technical component. The code is priced as bilateral, so modifier 50 does not increase payment.
