CPT® Code 92082

Visual field examination, unilateral or bilateral, with interpretation and report; intermediate examination (eg, at least 2 isopters on Goldmann perimeter, or semiquantitative, automated suprathreshold screening program, Humphrey suprathreshold automatic diagnostic test, Octopus program 33)

The CPT® Code 92082 refers to a visual field examination that assesses the total area in which a patient can perceive objects in their peripheral vision 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 potential loss of peripheral vision, which may indicate underlying conditions such as glaucomatous optic nerve damage or retinal diseases. The procedure is categorized as an intermediate examination, which involves the use of specific testing methods to evaluate the visual field comprehensively. These methods include manual perimetry tests, such as the Goldmann perimeter, which requires the identification of at least two isopters, or automated testing programs like the Humphrey suprathreshold automatic diagnostic test and the Octopus program 33. During the examination, one eye is occluded while the other is tested to ensure accurate results. The automated devices used in this process, such as the Octopus and the Humphrey-Zeiss field analyzer, utilize static perimetry techniques, where patients respond to stationary light stimuli presented in various locations. The data collected during the examination is processed by an onboard computer, which generates a detailed report of the visual field. The traditional Goldmann perimeter employs a kinetic perimetry approach, where a trained technician moves a light source while ensuring the patient maintains central fixation, ultimately creating a map of the patient's peripheral vision perception. The interpretation of the results and the generation of a report are integral components of this examination.
