Conjunctival pigmentations, unspecified eye

This code signifies the presence of abnormal discoloration or deposits of pigment on the conjunctiva, the clear membrane lining the eyelid and covering the white part of the eye. These pigmentations are not further specified as to their type (e.g., nevi, melanosis, foreign body) and the affected eye is also not specified.

Use this code when documentation indicates a conjunctival pigmentation without further detail regarding its specific nature or etiology. It is appropriate when the physician notes "conjunctival pigmentation" but does not specify if it's a nevus, melanosis, or another type, and does not indicate laterality.

• Avoid using this code if the specific type of conjunctival pigmentation (e.g., nevus, melanosis) is documented; instead, use a more specific code from the H11.2- category.
• Do not use this code if the laterality (right, left, bilateral) is specified; choose a more specific code from H11.131, H11.132, or H11.133.
• This code should be used when the documentation is truly ambiguous regarding both the type of pigmentation and the affected eye.
