ICD-10 Code H15.129 – Nodular episcleritis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.129 – Nodular episcleritis, unspecified eye
What it is
Nodular episcleritis is inflammation of the episclera, the thin tissue between the conjunctiva and sclera, with a localized raised nodule. This code specifies the eye is not further identified.
Clinical signs
Typical findings include sectoral redness, tenderness, and a visible or palpable episcleral nodule. Clinical features vary; refer to documentation if the record does not clearly identify laterality or nodular involvement.
When to use this code
Use H15.129 when the provider documents nodular episcleritis and does not specify right or left eye. It is also appropriate when the note confirms episcleritis with a nodular pattern but laterality is missing or unclear. Code only what is documented.
Do not use for
Do not use this code for simple episcleritis without a nodule, scleritis, or conjunctivitis. Check documentation if the eye condition is described differently or if another diagnosis better matches the record.
Coding tip
Verify both the nodular subtype and the unspecified-eye wording before assigning H15.129.
