ICD-10 Code H44.632 – Retained (old) magnetic foreign body in lens, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.632 – Retained (old) magnetic foreign body in lens, left eye
What it is
This code identifies an old, retained magnetic foreign body located in the lens of the left eye. Use it when documentation specifies the foreign body remains in the lens and the left eye is involved.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a known history of ocular foreign body, lens opacity, or visual disturbance, but you should code only when the retained lens foreign body is documented.
When to use this code
Use H44.632 when the record clearly states a retained or old magnetic foreign body in the left lens. It may appear in ophthalmology notes, imaging reports, or operative histories describing a chronic intra-lenticular foreign body. If laterality or lens location is not documented, check documentation before assigning the code.
Do not use for
Do not use this code for foreign bodies in the cornea, anterior chamber, vitreous, or other eye structures. Do not assign it if the note only says “foreign body in eye” without confirming the lens and left side.
Coding tip
Verify both the exact site and laterality; “old” and “retained” must be supported by the record.
