ICD-10 Code H18.831 – Recurrent erosion of cornea, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.831 – Recurrent erosion of cornea, right eye
What it is
This code identifies recurrent breakdown of the corneal surface in the right eye. It is used when the corneal epithelium repeatedly separates, causing episodes of irritation or pain.
Clinical signs
Typical findings include sudden eye pain, tearing, foreign-body sensation, light sensitivity, and blurred vision. Clinical features vary; refer to documentation.
When to use this code
Use H18.831 when the provider documents recurrent erosion affecting the right cornea. It fits follow-up visits for repeated episodes, chronic corneal instability, or a confirmed history of recurrent corneal epithelial defects in the right eye.
Choose this code when the record clearly specifies the right eye. If laterality is missing or the diagnosis is uncertain, check documentation before assigning the code.
Do not use for
Do not use it for a single, acute corneal abrasion without recurrence. Do not use it when the problem involves the left eye, both eyes, or another corneal disorder.
Coding tip
Verify laterality and the word “recurrent” in the provider note before coding H18.831.
