Scotoma of blind spot area, right eye

This code describes a scotoma, or an area of partial or complete vision loss, specifically affecting the blind spot in the right eye. The blind spot is the small area on the retina where the optic nerve enters, containing no photoreceptors.

Use this code when documentation indicates a patient presents with a visual field defect localized to the physiological blind spot of the right eye. This can be identified through visual field testing, such as perimetry, and confirmed by an ophthalmologist or optometrist.

• Ensure laterality is clearly documented (right eye).
• Distinguish from other types of scotomas (e.g., central, paracentral) which have different codes.
• Code any underlying cause of the scotoma, if known, as a primary diagnosis if applicable.
