ICD-10 Code H18.32 – Folds in Descemet’s membrane (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.32 – Folds in Descemet’s membrane
What it is
H18.32 identifies folds in Descemet’s membrane, the thin inner layer of the cornea. Use it when documentation specifically notes corneal folds involving this membrane.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible or slit-lamp-detected corneal folds, often described by an eye specialist after examination.
When to use this code
Use this code when the provider documents folds in Descemet’s membrane as the diagnosis. It is appropriate for ophthalmology notes, consults, or problem lists that identify this corneal finding. If the record only mentions corneal edema or another corneal change, check documentation before assigning H18.32.
Do not use for
Do not use this code for general corneal edema, scarring, or other corneal abnormalities without specific mention of Descemet’s membrane folds. Check documentation if the finding is unclear or recorded under a different corneal disorder.
Coding tip
Code H18.32 only when the provider names Descemet’s membrane folds explicitly in the chart.
