ICD-10 Code H44.64 – Retained (old) magnetic foreign body in posterior wall of globe (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H44.64 – Retained (old) magnetic foreign body in posterior wall of globe
What it is
This code identifies an old, retained magnetic foreign body embedded in the posterior wall of the eyeball. It indicates a chronic ocular foreign body rather than a fresh injury.
Clinical signs
Clinical features vary; refer to documentation. Patients may have a known history of eye trauma, persistent ocular discomfort, reduced vision, or imaging evidence of a retained metallic object in the posterior globe.
When to use this code
Use H44.64 when the record clearly states a retained, old magnetic foreign body in the posterior wall of the globe. Code it when the provider documents the location and chronic nature, especially after prior penetrating eye injury or confirmed imaging findings.
Use this code for the retained object itself, not for a general eye injury without that detail. Check documentation if the note only mentions “foreign body in eye” or does not specify that it is magnetic and old.
Do not use for
Do not use it for an acute foreign body injury, a nonmagnetic object, or a foreign body in another eye structure. Check documentation if the site is not the posterior wall of the globe.
Coding tip
Verify the provider documents both “retained/old” and “magnetic” before assigning H44.64.
