Scotoma of blind spot area, bilateral

This code signifies a scotoma, or an area of partial or complete vision loss, specifically affecting the physiological blind spot in both eyes. This visual field defect is typically a benign finding related to the optic disc's absence of photoreceptors.

Use this code when documentation clearly indicates a bilateral scotoma localized to the blind spot area, often identified during visual field testing. This typically applies to cases where a patient presents with visual disturbances, and subsequent examination confirms this specific finding.

• Ensure documentation specifies "bilateral" and "blind spot area" to support this code.
• Do not confuse with other types of scotomas (e.g., central, paracentral) or generalized visual field defects.
• Always review the complete visual field report and ophthalmologist's notes for precise localization and laterality.
