ICD-10 Code H15.113 – Episcleritis periodica fugax, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.113 – Episcleritis periodica fugax, bilateral
What it is
H15.113 identifies episodic inflammation of the episclera in both eyes. Use it when the record specifically documents episcleritis periodica fugax affecting the bilateral episclera.
Clinical signs
Typical findings include recurrent redness, mild eye discomfort, and localized episcleral injection. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral episcleritis periodica fugax, including recurrent or transient episodes in both eyes. It is appropriate when the diagnosis is confirmed in the chart and no more specific alternative is documented.
If the note only says “episcleritis” without laterality or recurrence, check documentation before assigning H15.113. Code the documented condition as written and avoid assuming bilateral involvement.
Do not use for
Do not use this code for scleritis, conjunctivitis, or nonspecific eye redness. Check documentation if the record does not clearly identify episodic bilateral episcleritis.
Coding tip
Confirm both laterality and the recurrent “periodica fugax” wording before assigning H15.113.
