ICD-10 Code H59.0 – Disorders of the eye following cataract surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.0 – Disorders of the eye following cataract surgery
What it is
H59.0 identifies eye disorders that occur after cataract surgery. Use it when the record links a postoperative ocular problem to the cataract procedure.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart will describe a postoperative eye complication, such as inflammation, edema, or another abnormal finding after cataract surgery.
When to use this code
Use this code when the provider documents a disorder of the eye as a consequence of cataract surgery. It fits postoperative complications clearly tied to the procedure, not routine recovery. If the note is vague about the cause, check documentation before assigning it.
Do not use for
Do not use H59.0 for unrelated eye disease or for normal postoperative follow-up without a documented complication. If the condition is not stated as following cataract surgery, this code is not appropriate.
Coding tip
Link the diagnosis to cataract surgery in the provider note before coding H59.0.
