Visual agnosia

Visual agnosia is a neurological disorder characterized by an inability to recognize or interpret visual stimuli despite intact visual acuity and cognitive function. Patients can see objects but cannot identify them, often due to damage in the visual association areas of the brain. This condition impairs the brain's ability to process and make sense of visual information.

This code is used when documentation specifies a diagnosis of visual agnosia, indicating a patient's inability to recognize objects, faces, or symbols visually. It applies to cases where the patient's eyes are functioning correctly, but the brain cannot interpret the visual input. Supporting documentation should clearly differentiate this from other visual impairments or cognitive deficits.

• Differentiate from other agnosias (e.g., auditory, tactile) which have distinct codes.
• Ensure documentation specifies "visual" agnosia to avoid confusion with general agnosia (R48.8).
• Code any underlying neurological condition (e.g., stroke, dementia) as a primary diagnosis if it is the cause of the visual agnosia.
