ICD-10 Code H11.22 – Conjunctival Granuloma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.22 – Conjunctival granuloma
What it is
H11.22 identifies a granulomatous lesion of the conjunctiva, the thin membrane covering the eye and inner eyelids. Use it for a documented conjunctival granuloma, not for nonspecific redness or irritation.
Clinical signs
Typical findings include a localized conjunctival nodule or mass, often with a chronic inflammatory appearance. Clinical features vary; refer to documentation for laterality, size, and whether the lesion is described as granulomatous.
When to use this code
Use H11.22 when the provider documents conjunctival granuloma as the diagnosis, such as after an eye exam or ophthalmology evaluation. It is also appropriate when the record clearly describes a granulomatous lesion of the conjunctiva. If the note only says “eye lesion” or “conjunctivitis,” check documentation.
Do not use for
Do not use this code for general conjunctivitis, pinguecula, or other non-granulomatous conjunctival disorders. If the lesion is elsewhere on the eye or the diagnosis is uncertain, check documentation.
Coding tip
Code H11.22 only when the conjunctival granuloma is explicitly documented; otherwise, query for the exact ocular diagnosis.
