ICD-10 Code H59.023 – Cataract (lens) fragments in eye following cataract surgery, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.023 – Cataract (lens) fragments in eye following cataract surgery, bilateral
What it is
H59.023 identifies retained cataract lens fragments in both eyes after cataract surgery. Use it when operative or follow-up documentation confirms postoperative lens material remains in the eye.
Clinical signs
Findings may include persistent intraocular inflammation, blurred vision, pain, or delayed recovery after surgery. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral retained lens fragments as a postoperative complication of cataract surgery. It may apply during postoperative visits, evaluation for ongoing symptoms, or follow-up after fragment removal if the condition is still noted.
Confirm that the fragments are in both eyes and that the issue is tied to cataract surgery, not another lens disorder. Check documentation if the laterality or postoperative relationship is unclear.
Do not use for
Do not use this code for uncomplicated cataract surgery, nonspecific postoperative eye pain, or retained fragments in only one eye. Do not use it when the record does not link the finding to cataract surgery.
Coding tip
Verify laterality and postoperative causation in the note before assigning H59.023.
