ICD-10 Code H18.839 – Recurrent erosion of cornea, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.839 – Recurrent erosion of cornea, unspecified eye
What it is
This code identifies recurrent breakdown of the corneal surface in an unspecified eye. It is used when the chart documents recurrent corneal erosion but does not name the right or left eye.
Clinical signs
Typical findings include repeated episodes of eye pain, tearing, light sensitivity, and foreign-body sensation, often on waking. Clinical features vary; refer to documentation.
When to use this code
Use H18.839 when the provider documents recurrent corneal erosion and laterality is not stated or cannot be determined from the record. It also fits follow-up visits for a known recurrent erosion in an unspecified eye. If the note identifies a specific eye, code that laterality instead.
Do not use for
Do not use this code for a single, nonrecurrent corneal abrasion or for corneal disorders without erosion. Check documentation if the eye is specified or if the condition is described differently.
Coding tip
Confirm both recurrence and laterality before assigning H18.839.
