ICD-10 Code H44.643 – Retained (old) magnetic foreign body in posterior wall of globe, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.643 – Retained (old) magnetic foreign body in posterior wall of globe, bilateral
What it is
H44.643 identifies a retained, old magnetic foreign body located in the posterior wall of both globes. Use it when documentation confirms an old intraocular or globe-wall metallic fragment that remains present bilaterally.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a history of ocular metal exposure, imaging evidence of retained foreign material, or chronic ocular irritation related to the old bilateral globe injury.
When to use this code
Use this code when the provider documents a retained magnetic foreign body in the posterior wall of both eyes, and the injury is described as old or longstanding. It fits follow-up records, problem lists, or imaging reports confirming persistence. Check documentation if laterality or location is unclear.
Do not use for
Do not use it for a new, acute eye foreign body or for nonmagnetic material. If the record does not specify bilateral posterior wall involvement, verify the exact site and laterality before coding.
Coding tip
Confirm both “retained/old” status and bilateral posterior wall location in the chart before assigning H44.643.
