CPT® Code 92083

Visual field examination, unilateral or bilateral, with interpretation and report; extended examination (eg, Goldmann visual fields with at least 3 isopters plotted and static determination within the central 30°, or quantitative, automated threshold perimetry, Octopus program G-1, 32 or 42, Humphrey visual field analyzer full threshold programs 30-2, 24-2, or 30/60-2)

The CPT® Code 92083 refers to a comprehensive visual field examination that assesses the extent of a patient's peripheral vision while maintaining focus on a central point. This examination can be performed on one eye (unilateral) or both eyes (bilateral) and is crucial for identifying potential vision loss due to various ocular conditions. The procedure specifically targets the detection of peripheral vision loss, which may be indicative of underlying issues such as glaucomatous optic nerve damage or retinal diseases. During the examination, one eye is occluded to isolate the testing of the other eye, allowing for a more accurate assessment of visual field integrity.

An extended visual field examination encompasses advanced testing methodologies, including quantitative automated perimetry and manual perimetry techniques. These methods involve the use of sophisticated devices, such as the Octopus visual field analyzer and the Humphrey-Zeiss field analyzer, which are equipped with onboard computers to facilitate the testing process. The tests may include multilevel threshold testing or the plotting of at least three isopters on the Goldmann visual field chart, focusing on static determination within the central 30 degrees of vision. The automated devices utilize stationary pinpoint light sources or dots projected within a large, white bowl, prompting the patient to respond when they perceive light or movement in various locations or intensities. The data collected during the examination is then processed and interpreted, resulting in a detailed vision field report that aids in clinical decision-making.
