ICD-10 Code H18.332 – Rupture in Descemet’s membrane, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.332 – Rupture in Descemet’s membrane, left eye
What it is
H18.332 identifies a rupture of Descemet’s membrane in the left eye. This is a corneal injury involving the membrane behind the corneal stroma, and you should code the left eye specifically.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include corneal edema, decreased visual acuity, and signs of anterior segment trauma or prior corneal injury.
When to use this code
Use this code when the provider documents rupture in Descemet’s membrane affecting the left eye. It applies to encounters where the diagnosis is confirmed or clearly stated in the chart. If laterality is not documented, check the record before assigning a code.
Do not use for
Do not use this code for corneal disorders that do not involve Descemet’s membrane rupture. If the documentation only mentions corneal edema or eye trauma without this specific finding, check documentation.
Coding tip
Always confirm the eye laterality and the exact membrane injury before coding H18.332.
