ICD-10 Code H18.832 – Recurrent erosion of cornea, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.832 – Recurrent erosion of cornea, left eye
What it is
H18.832 identifies recurrent breakdown of the corneal surface in the left eye. The cornea repeatedly loses its outer epithelial layer, causing episodes of pain and irritation.
Clinical signs
Typical findings include sudden eye pain, tearing, light sensitivity, and a foreign-body sensation, often on waking. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents recurrent corneal erosion specifically in the left eye. It fits repeated episodes or a diagnosed recurrent erosion pattern affecting that eye. Check documentation if laterality is unclear or if the note describes only a single, acute abrasion.
Do not use for
Do not use this code for corneal abrasions, ulcers, or erosion in the right eye or unspecified eye. If the chart does not confirm recurrence or laterality, check documentation.
Coding tip
Verify both recurrence and left-eye laterality in the provider note before assigning H18.832.
