Generalized contraction of visual field, left eye

This code indicates a generalized constriction of the visual field affecting the left eye. This means the patient experiences a reduction in their overall peripheral vision in the left eye, making their field of view narrower than normal. It signifies a non-specific, widespread loss of visual field rather than a localized defect.

This code is appropriate when documentation specifies a generalized contraction or constriction of the visual field limited to the left eye. Clinical findings such as those from perimetry or visual field testing, indicating a concentric narrowing of the visual field in the left eye, support its use. It should be used when the underlying cause of the generalized contraction is not specified or is unknown.

• Ensure documentation clearly specifies "generalized" or "concentric" contraction of the visual field and laterality (left eye).
• Do not use this code for specific visual field defects (e.g., scotomas, hemianopsia); those have more specific codes.
• Always sequence an underlying cause, if known and documented, before this code.
