ICD-10 Code H59.099 – Other disorders of unspecified eye following cataract surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.099 – Other disorders of unspecified eye following cataract surgery
What it is
This code identifies an unspecified eye disorder that occurs after cataract surgery. Use it when the postoperative eye problem is documented, but the exact disorder is not named.
Clinical signs
Clinical features vary; refer to documentation. You may see postoperative eye discomfort, inflammation, visual change, or another abnormal finding linked to prior cataract surgery.
When to use this code
Use H59.099 when the record states a disorder of the eye after cataract surgery and the provider does not specify a more exact diagnosis. It is appropriate for postoperative complications or other documented eye abnormalities tied to the surgery. Check documentation if the laterality or specific disorder is unclear.
Do not use for
Do not use this code for routine postoperative follow-up without a complication. Do not use it when the chart identifies a specific post-cataract disorder that has its own code.
Coding tip
Code the documented postoperative eye disorder as specifically as possible; if the record is vague, H59.099 is the fallback.
