H05.5Retained (old) foreign body following penetrating wound of orbit

H05.5 is the ICD-10-CM diagnosis code for retained (old) foreign body following penetrating wound of orbit. It belongs to category H05 (disorders of orbit), block H00-H05 (disorders of eyelid, lacrimal system and orbit) 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 4 subcodes must be used instead.

Within H05 (disorders of orbit), H05.5 is specifically for retained (old) foreign body following penetrating wound of orbit. Related codes cover acute inflammation of orbit (H05.0), chronic inflammatory disorders of orbit (H05.1), Exophthalmic conditions (H05.2), deformity of orbit (H05.3), enophthalmos (H05.4), other disorders of orbit (H05.8) and unspecified disorder of orbit (H05.9).

To report this condition, pick the subcode that matches the documentation: H05.50 (orbit), H05.51 (orbit), H05.52 (orbit) and H05.53 (orbits).

Don't report H05.5 together with the conditions in its Excludes1 note: current penetrating wound of orbit (S05.4-).

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

Use an additional code to identify the type of retained foreign body (Z18.-).

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