ICD-10 Code H44.32 – Siderosis of eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.32 – Siderosis of eye
What it is
Siderosis of eye is iron deposition in ocular tissues, usually after a retained iron-containing foreign body. It can damage the eye over time and may affect vision.
Clinical signs
Findings may include ocular inflammation, iris discoloration, cataract, retinal changes, or progressive visual loss. Clinical features vary; refer to documentation.
When to use this code
Use H44.32 when the provider documents siderosis of the eye or iron deposition from an intraocular or retained ocular foreign body. Apply it when the condition is confirmed, not merely suspected. Check documentation for laterality and associated eye injury details.
Do not use for
Do not use this code for a superficial corneal foreign body or for non-iron ocular debris without siderosis. Do not assign it when documentation only mentions possible retained metal without confirmed eye involvement.
Coding tip
Look for wording such as “siderosis bulbi” or “iron foreign body” in the ophthalmology note before coding H44.32.
