ICD-10 Code H15.123 – Nodular episcleritis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.123 – Nodular episcleritis, bilateral
What it is
This code identifies nodular episcleritis affecting both eyes. It refers to inflammation of the episclera with a localized nodule in each eye.
Clinical signs
Typical findings include sectoral redness, mild to moderate eye discomfort, and a raised episcleral nodule. Clinical features vary; refer to documentation.
When to use this code
Use H15.123 when the provider documents nodular episcleritis in both eyes, or bilateral episcleral nodules with inflammation. Code it only when laterality is clearly stated as bilateral. If the note does not specify laterality or the diagnosis is uncertain, check documentation.
Do not use for
Do not use this code for simple episcleritis without nodules, unilateral disease, or other ocular redness causes. Do not assign it when the record only says “eye inflammation” without a confirmed diagnosis.
Coding tip
Confirm both the nodular diagnosis and bilateral laterality in the assessment before assigning H15.123.
