ICD-10 Code H10.41 – Chronic giant papillary conjunctivitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H10.41 – Chronic giant papillary conjunctivitis
What it is
H10.41 identifies chronic giant papillary conjunctivitis, a long-lasting inflammatory condition of the palpebral conjunctiva. It is commonly linked to mechanical irritation, often from contact lenses or ocular foreign material.
Clinical signs
Typical findings include conjunctival redness, itching, mucus discharge, and large papillae on the upper tarsal conjunctiva. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents chronic giant papillary conjunctivitis by name or clearly describes a chronic papillary conjunctival reaction. You may also use it when the chart links the condition to contact lens intolerance with documented giant papillae. Check documentation if laterality or acuity is unclear.
Do not use for
Do not use this code for simple allergic conjunctivitis, acute conjunctivitis, or nonspecific eye irritation without giant papillary changes. If the record does not support chronic disease, check documentation.
Coding tip
Code from the provider’s exact diagnosis and avoid assuming contact lens causation unless it is documented.
