ICD-10 Code H15.122 – Nodular episcleritis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.122 – Nodular episcleritis, left eye
What it is
This code identifies nodular episcleritis affecting the left eye. It refers to localized inflammation of the episclera with a visible nodule or raised area.
Clinical signs
Typical findings include sectoral redness, tenderness, and a discrete episcleral nodule in the left eye. Clinical features vary; refer to documentation if the presentation is not clearly described.
When to use this code
Use H15.122 when the provider documents nodular episcleritis specifically in the left eye. It also fits follow-up or active-episode visits when the diagnosis is confirmed in the record. If laterality is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for nonspecific conjunctivitis, scleritis, or episcleritis without nodularity or left-eye laterality. Check documentation if the note only says “eye inflammation.”
Coding tip
Verify both the nodular type and left-eye laterality in the provider note before coding.
