ICD-10 Code H11.221 – Conjunctival granuloma, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.221 – Conjunctival granuloma, right eye
What it is
H11.221 identifies a granulomatous lesion of the conjunctiva in the right eye. Use it when documentation specifies a conjunctival granuloma affecting only the right eye.
Clinical signs
Clinical features may include a localized conjunctival mass or nodule with redness or irritation. Clinical features vary; refer to documentation for eye laterality and whether the lesion is truly granulomatous.
When to use this code
Use this code when the provider documents a conjunctival granuloma of the right eye in the assessment, diagnosis, or final impression. It also fits when the note clearly links the lesion to the right conjunctiva and no broader conjunctival disorder is specified.
If the record only says “eye lesion” or “conjunctival growth,” you should check documentation before coding H11.221. Laterality matters, so confirm the right eye is identified.
Do not use for
Do not use this code for left-eye or bilateral conjunctival granuloma, or for unspecified conjunctival lesions. If the documentation describes another conjunctival condition, code that diagnosis instead.
Coding tip
Always verify laterality and the exact conjunctival diagnosis in the note before assigning H11.221.
