ICD-10 Code H59.09 – Other disorders of the eye following cataract surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.09 – Other disorders of the eye following cataract surgery
What it is
H59.09 identifies other eye problems that occur after cataract surgery and are not classified elsewhere. Use it for postoperative ocular complications when the record does not fit a more specific diagnosis.
Clinical signs
Findings depend on the complication and may include decreased vision, pain, inflammation, or abnormal postoperative exam results. Clinical features vary; refer to documentation.
When to use this code
Use H59.09 when the provider documents a postoperative eye disorder after cataract surgery and no more specific code applies. It is appropriate for charted complications tied to the surgery, not for routine follow-up alone. Check documentation for the exact postoperative condition.
Do not use for
Do not use this code for normal aftercare, routine post-cataract follow-up, or complications that have a more specific ICD-10-CM code. Do not assign it if the record does not link the eye disorder to cataract surgery.
Coding tip
Confirm the surgeon’s documentation names a postoperative eye disorder and specifically connects it to cataract surgery before assigning H59.09.
