ICD-10 Code H44.633 – Retained (old) magnetic foreign body in lens, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.633 – Retained (old) magnetic foreign body in lens, bilateral
What it is
This code identifies an old, retained magnetic foreign body located in both lenses of the eyes. Use it when the documentation specifically states the foreign body is present in the lens and bilateral.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a history of ocular metal exposure, visible lens foreign body on exam, and related lens opacity or visual disturbance.
When to use this code
Use H44.633 when the provider documents a retained, old magnetic foreign body in the lens of both eyes. It fits cases where the object is still present and the record clearly identifies bilateral involvement.
Choose this code for chronic or previously acquired lens foreign bodies, not for a fresh injury unless the note states it is retained or old. Check documentation if the laterality or lens location is unclear.
Do not use for
Do not use this code for a foreign body in the cornea, conjunctiva, or other eye structures. Do not use it if the record does not confirm both lens involvement or the retained, old nature of the foreign body.
Coding tip
Confirm three elements in the note: retained or old, magnetic foreign body, and bilateral lens involvement.
