ICD-10 Code H18.311 – Folds and rupture in Bowman’s membrane, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.311 – Folds and rupture in Bowman’s membrane, right eye
What it is
H18.311 identifies folds or a rupture in Bowman’s membrane of the right cornea. Use it when the documentation specifically names this corneal layer abnormality in the right eye.
Clinical signs
Clinical features vary; refer to documentation. Findings may include corneal irregularity noted on slit-lamp exam and symptoms such as blurred vision or visual distortion.
When to use this code
Use this code when the clinician documents folds or rupture of Bowman’s membrane in the right eye. It applies to a right-eye corneal finding, not a general corneal scar or unspecified corneal disorder. Check the note for laterality and the exact anatomic term.
Do not use for
Do not use it for left eye, bilateral disease, or unspecified eye documentation. Do not assign it when the record only mentions corneal injury or opacity without Bowman’s membrane involvement.
Coding tip
Verify that the provider names Bowman’s membrane and the right eye; if either detail is missing, check documentation before coding.
