ICD-10 Code H11.139 – Conjunctival Pigmentations, Unspecified Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.139 – Conjunctival pigmentations, unspecified eye
What it is
This code identifies pigmentation on the conjunctiva, the clear membrane covering the white of the eye, when the eye is not specified. Use it for documented conjunctival pigment changes without a more precise diagnosis.
Clinical signs
Findings may include visible brown, black, or slate-colored spots or patches on the conjunctiva. Clinical features vary; refer to documentation for laterality, extent, and whether the pigmentation is stable or changing.
When to use this code
Use H11.139 when the provider documents conjunctival pigmentation and does not name a more specific condition or eye. It is appropriate for incidental findings recorded during an eye exam, follow-up visit, or consultation. If the chart identifies a different conjunctival lesion, code that diagnosis instead.
Do not use for
Do not use this code for pigmentation of the eyelid, cornea, iris, or skin around the eye. Check documentation if the finding is described as a nevus, melanoma, or another specific conjunctival disorder.
Coding tip
Verify that the note says conjunctiva and that the eye is unspecified before assigning H11.139.
