ICD-10 Code H15.102 – Unspecified episcleritis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.102 – Unspecified episcleritis, left eye
What it is
H15.102 identifies episcleritis affecting the left eye when the specific type is not documented. It refers to inflammation of the episcleral tissue, a superficial layer over the white part of the eye.
Clinical signs
Typical findings include localized redness, mild discomfort, and eye irritation. Clinical features vary; refer to documentation if the record does not clearly describe laterality or whether the episcleritis is simple or nodular.
When to use this code
Use this code when the provider documents episcleritis in the left eye but does not specify a subtype. It is also appropriate when the note confirms episcleritis and laterality, yet no further detail is available. Check documentation if the diagnosis is uncertain.
Do not use for
Do not use this code for scleritis, conjunctivitis, or nonspecific “red eye” without a documented episcleritis diagnosis. If the chart does not confirm the left eye, do not assign this code.
Coding tip
Always verify both laterality and the provider’s exact wording before coding H15.102.
