Conjunctival pigmentations, bilateral

This code describes the presence of abnormal discoloration or deposits of pigment on the conjunctiva, affecting both eyes. These pigmentations can vary in color and may be benign or indicative of underlying systemic conditions or localized pathology.

Use this code when documentation specifies bilateral conjunctival pigmentations, regardless of their etiology (e.g., nevus, melanosis, drug-induced). This code is appropriate when the physician has identified and documented the presence of pigmentation in both conjunctivae.

• Ensure documentation clearly specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• If the specific type of pigmentation (e.g., nevus, melanosis) is documented, consider using a more specific code if available within the H11.1- category.
• Code any underlying systemic condition causing the pigmentation (e.g., Addison's disease) as a primary diagnosis, with this code as a secondary diagnosis.
