ICD-10 Code H59.021 – Cataract (lens) fragments in eye following cataract surgery, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H59.021 – Cataract (lens) fragments in eye following cataract surgery, right eye
What it is
This code identifies retained cataract lens fragments in the right eye after cataract surgery. Use it when postoperative lens material remains in the eye and is documented as a complication.
Clinical signs
Findings may include persistent inflammation, reduced vision, ocular pain, or signs of a retained fragment on exam. Clinical features vary; refer to documentation.
When to use this code
Use H59.021 when the provider documents cataract lens fragments in the right eye after surgery, including retained nuclear or cortical material. Code it for postoperative complications tied to the prior cataract procedure. If laterality or the postoperative nature is unclear, check documentation.
Do not use for
Do not use it for routine postoperative follow-up without a documented retained fragment. Do not assign it if the issue is in the left eye, both eyes, or if the note does not link the finding to cataract surgery.
Coding tip
Confirm both the postoperative complication and right-eye laterality in the provider note before assigning H59.021.
