ICD-10 Code H11.132 – Conjunctival Pigmentations, Left Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.132 – Conjunctival pigmentations, left eye
What it is
This code identifies pigmentation located on the conjunctiva of the left eye. Use it when documentation describes a pigmented conjunctival lesion or discoloration specific to the left side.
Clinical signs
Findings may include a visible brown, black, or otherwise pigmented spot on the conjunctiva. Clinical features vary; refer to documentation for laterality and whether the lesion is stable, new, or changing.
When to use this code
Use H11.132 when the provider documents conjunctival pigmentation in the left eye and no more specific diagnosis is given. It is appropriate for office, ophthalmology, or referral notes that clearly identify the lesion’s location. If the record only says “pigmented lesion” without laterality, check documentation.
Do not use for
Do not use this code for pigmentation of the cornea, iris, or eyelid. Also avoid it when the documentation supports a different conjunctival disorder or the eye laterality is not confirmed.
Coding tip
Confirm that the note specifies the left conjunctiva before assigning H11.132.
