ICD-10 Code H18.322 – Folds in Descemet’s membrane, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.322 – Folds in Descemet’s membrane, left eye
What it is
This code identifies folds in Descemet’s membrane affecting the left eye. It describes a corneal finding rather than a disease cause, so you should code it when documentation specifically notes this membrane abnormality.
Clinical signs
Findings may include visible corneal folds on eye examination, often noted on slit-lamp evaluation. Clinical features vary; refer to documentation.
When to use this code
Use H18.322 when the provider documents folds in Descemet’s membrane in the left eye. Apply it for confirmed corneal findings, including postoperative or trauma-related documentation, if the record names this specific left-eye abnormality. Check documentation if the laterality is unclear.
Do not use for
Do not use this code for nonspecific corneal edema, scars, or other corneal opacities without documented Descemet’s membrane folds. If the finding is in the right eye or both eyes, use the appropriate code instead.
Coding tip
Always verify laterality and use the exact corneal term documented by the provider.
