ICD-10 Code H44.733 – Retained (nonmagnetic) (old) foreign body in lens, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.733 – Retained (nonmagnetic) (old) foreign body in lens, bilateral
What it is
This code identifies an old, retained nonmagnetic foreign body located in both eye lenses. Use it when documentation confirms a chronic lens foreign body rather than an acute penetrating injury.
Clinical signs
Findings may include a documented lens opacity or visible foreign material in the lens, sometimes with reduced vision or glare. Clinical features vary; refer to documentation.
When to use this code
Use H44.733 when the provider documents a retained, nonmagnetic, old foreign body in both lenses. It fits bilateral lens involvement, whether discovered incidentally or during follow-up for prior eye trauma. If the note does not clearly specify lens location and bilateral involvement, check documentation.
Do not use for
Do not use this code for acute ocular foreign bodies, magnetic foreign bodies, or foreign bodies in other eye structures. It is also not appropriate when the record only states a corneal or conjunctival foreign body.
Coding tip
Confirm both “old” and “bilateral lens” in the chart before assigning H44.733.
