ICD-10 Code H59.091 – Other disorders of the right eye following cataract surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.091 – Other disorders of the right eye following cataract surgery
What it is
Use this code for a right-eye disorder that develops after cataract surgery and is not classified elsewhere. It identifies a postoperative complication or residual problem affecting the right eye.
Clinical signs
Clinical features vary; refer to documentation. Common postoperative findings may include decreased vision, discomfort, inflammation, or other abnormal right-eye changes noted after cataract extraction.
When to use this code
Assign H59.091 when the provider documents a specific right-eye disorder as a consequence of cataract surgery and no more specific ICD-10-CM code applies. Use it for postoperative conditions tied to the surgery, not for routine follow-up alone. Check documentation for laterality and the exact complication.
Do not use for
Do not use this code for normal postoperative care, unspecified eye complications, or problems in the left eye. If the record names a different postoperative diagnosis, code that condition instead.
Coding tip
Verify that the chart links the right-eye disorder to prior cataract surgery before assigning H59.091.
