In simple words: This code indicates an older, magnetic object is stuck inside the eye.A separate code will also be used to specify what that object is.

Retained (old) intraocular foreign body, magnetic. This code is used to indicate the presence of an intraocular foreign body that is magnetic and has been retained for a significant period. An additional code should be used to identify the specific type of magnetic foreign body (Z18.11).

Example 1: A 45-year-old male presents with blurred vision in his right eye. Upon examination, a small metallic foreign body is discovered embedded in the vitreous. Imaging studies confirm it is magnetic and has been present for several months, consistent with a work-related incident he recalls from some time ago., A 60-year-old female complains of floaters and flashes of light in her left eye. An ophthalmological examination reveals a retained metallic foreign body in the lens, confirmed to be magnetic. The patient reports a history of metal work but cannot recall a specific incident., A child presents with decreased vision and pain in their left eye. Imaging shows an old, retained magnetic foreign body in the anterior chamber.Parents state the child was playing with magnets several months prior but they didn’t realize one might have gotten in the eye.

Documentation should include details about the foreign body (size, location, magnetic properties), the duration it has been retained, associated symptoms, ophthalmological findings, imaging results, and any procedures performed.

** Excludes1: current intraocular foreign body (S05.-) Excludes2: retained foreign body in eyelid (H02.81-) retained (old) foreign body following penetrating wound of orbit (H05.5-) retained (old) intraocular foreign body, nonmagnetic (H44.7-)
