ICD-10 Code H59.011 – Keratopathy (bullous aphakic) following cataract surgery, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.011 – Keratopathy (bullous aphakic) following cataract surgery, right eye
What it is
This code identifies bullous aphakic keratopathy in the right eye after cataract surgery. It describes corneal damage with fluid-filled blisters that develops as a postoperative complication.
Clinical signs
Typical findings include corneal edema, epithelial bullae, pain, tearing, photophobia, and blurred vision. Clinical features vary; refer to documentation.
When to use this code
Use H59.011 when the provider documents bullous aphakic keratopathy in the right eye and links it to prior cataract surgery. It is appropriate for postoperative corneal complications, not for routine aphakia alone. Confirm laterality and the postoperative relationship in the record.
Do not use for
Do not use this code for keratopathy in the left eye, unspecified eye, or corneal disease unrelated to cataract surgery. Check documentation if the record does not clearly state a postoperative cause.
Coding tip
Always verify the eye and the surgical history, because this code requires both laterality and a cataract-surgery complication.
