2026 ICD-10-CM Diagnosis Code H59.02 – Cataract (lens) fragments in eye following cataract surgery
What it is
Use this code for retained cataract lens fragments in the eye after cataract surgery. It identifies a postoperative complication where lens material remains inside the eye.
Clinical signs
Findings may include ocular inflammation, pain, blurred vision, or elevated intraocular pressure after surgery. Clinical features vary; refer to documentation.
When to use this code
Use H59.02 when the provider documents cataract fragments or retained lens material in the eye following cataract surgery. Code it for postoperative cases, not for routine aftercare or expected healing. Make sure the note links the fragments to the prior surgery.
Do not use for
Do not use this code for uncomplicated cataract surgery recovery or for other postoperative eye problems. Check documentation if the record describes a different retained foreign body or another complication.
Coding tip
Confirm the complication is explicitly documented as lens fragments in the eye after cataract surgery before assigning H59.02.
