CPT® Code 92081

Visual field examination, unilateral or bilateral, with interpretation and report; limited examination (eg, tangent screen, Autoplot, arc perimeter, or single stimulus level automated test, such as Octopus 3 or 7 equivalent)

A visual field examination is a diagnostic procedure that assesses the total area in which a patient can perceive objects while maintaining focus on a central point. This examination can be conducted on one eye (unilateral) or both eyes (bilateral) and is crucial for identifying blind spots or any loss of peripheral vision, which can indicate various ocular or neurological conditions. During the examination, one eye is occluded to ensure that the other eye is tested in isolation. The limited examination referred to in CPT® Code 92081 utilizes a wide-field screening protocol designed to evaluate the static field of vision. This essentially serves as a screening test at a single stimulus level. The procedure may involve a tangent screen test, where the patient is positioned three feet away from a target displayed on a screen. The patient is instructed to focus on the central target and notify the examiner when they perceive objects moving into their peripheral vision. Alternatively, automated perimetry may be employed, wherein the patient sits in front of a concave dome, fixating on a central object, and is required to press a button each time they detect a small flash of light in their peripheral vision. The results of the visual field examination are interpreted, and a written report detailing the findings is generated, providing essential information for further clinical evaluation and management.
