ICD-10 Code H18.11 – Bullous keratopathy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H18.11 – Bullous keratopathy, right eye
What it is
Bullous keratopathy, right eye means corneal swelling in the right eye that leads to painful fluid-filled blisters on the cornea. It reflects endothelial dysfunction or corneal failure affecting vision and comfort.
Clinical signs
Typical findings include corneal edema, epithelial bullae, eye pain, tearing, glare, and blurred vision. Clinical features vary; refer to documentation.
When to use this code
Use H18.11 when the provider documents bullous keratopathy limited to the right eye. Apply it for corneal edema with bullae, postoperative corneal decompensation, or other documented corneal endothelial failure in that eye. Confirm laterality in the record before coding.
Do not use for
Do not use this code for left eye or bilateral disease, or for nonspecific corneal edema without bullous keratopathy documented. Check documentation if the cause or laterality is unclear.
Coding tip
Always verify the affected eye and whether the provider specifically states bullous keratopathy rather than general corneal edema.
