H44.6Retained (old) intraocular foreign body, magnetic

H44.6 is the ICD-10-CM diagnosis code for retained (old) intraocular foreign body, magnetic. It belongs to category H44 (disorders of globe), block H43-H44 (disorders of vitreous body and globe) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 7 subcodes must be used instead.

Within H44 (disorders of globe), H44.6 is specifically for retained (old) intraocular foreign body, magnetic. Related codes cover purulent endophthalmitis (H44.0), other endophthalmitis (H44.1), degenerative myopia (H44.2), other and unspecified degenerative disorders of globe (H44.3), hypotony of eye (H44.4), degenerated conditions of globe (H44.5), retained (old) intraocular foreign body, nonmagnetic (H44.7), other disorders of globe (H44.8) and 1 more.

To report this condition, pick the subcode that matches the documentation: H44.60 (magnetic), H44.61 (chamber), H44.62 (body), H44.63 (lens), H44.64 (globe), H44.65 (body) and H44.69 (in other or multiple sites).

Don't report H44.6 together with the conditions in its Excludes1 note: current intraocular foreign body (S05.-).

The conditions in its Excludes2 note aren't part of H44.6, but may be coded alongside it if the patient has both: retained foreign body in eyelid (H02.81-), retained (old) foreign body following penetrating wound of orbit (H05.5-) and retained (old) intraocular foreign body, nonmagnetic (H44.7-).

Use an additional code to identify magnetic foreign body (Z18.11).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
