ICD-10 Code H05.50 – Retained (old) foreign body following penetrating wound of unspecified orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.50 – Retained (old) foreign body following penetrating wound of unspecified orbit
What it is
This code identifies a retained foreign body in the orbit that remains after an old penetrating injury. Use it when documentation shows a past penetrating wound and an unspecified orbital location.
Clinical signs
Findings may include a documented history of orbital penetration, persistent foreign material, or ongoing orbital symptoms. Clinical features vary; refer to documentation.
When to use this code
Use H05.50 when the record clearly states an old retained foreign body in the orbit after a penetrating wound, and the specific orbital site is not documented. It is appropriate for follow-up or problem-list coding when the injury is no longer acute. Check documentation if the note does not confirm a retained object.
Do not use for
Do not use this code for acute orbital foreign bodies or injuries without a retained object. Also avoid it when the foreign body location is specified elsewhere in the orbit.
Coding tip
Confirm both “retained” and “old penetrating wound” in the note before assigning H05.50.
