Conjunctival pigmentations, right eye

This diagnosis code signifies the presence of abnormal discoloration or dark spots on the conjunctiva of the right eye. These pigmentations can vary in size, shape, and color, and may be benign or indicative of underlying conditions.

Use this code when documentation specifies pigmentary changes on the conjunctiva, specifically affecting the right eye. This applies to conditions such as conjunctival nevi, melanosis, or other forms of pigmentation. Documentation should clearly indicate the location as the right eye.

• Ensure laterality is precisely documented; separate codes exist for the left eye and bilateral involvement.
• Distinguish from scleral pigmentations, which are coded differently.
• If the underlying cause of the pigmentation is known (e.g., nevus), consider coding that specific condition first, if appropriate, and then this code as a secondary diagnosis.
