ICD-10 Code H44.642 – Retained (old) magnetic foreign body in posterior wall of globe, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.642 – Retained (old) magnetic foreign body in posterior wall of globe, left eye
What it is
This code identifies a previously retained magnetic foreign body embedded in the posterior wall of the left globe. Use it when documentation specifies an old, retained intraocular or globe-wall foreign body on the left side.
Clinical signs
Findings may include a documented history of ocular metallic injury, persistent foreign body on exam or imaging, and localized globe involvement. Clinical features vary; refer to documentation.
When to use this code
Use H44.642 when the record clearly states a retained old magnetic foreign body in the posterior wall of the left globe. It may also apply when prior injury is documented and the foreign body remains present, stable, or longstanding. Code only when the left eye is specified.
Do not use for
Do not use this code for a recent eye foreign body, a nonmagnetic foreign body, or a foreign body outside the globe wall. Check documentation if the laterality or retained status is unclear.
Coding tip
Confirm both “retained/old” and “left eye” in the note before assigning H44.642.
