S05.4Penetrating wound of orbit with or without foreign body

S05.4 is the ICD-10-CM diagnosis code for penetrating wound of orbit with or without foreign body. It belongs to category S05 (injury of eye and orbit), block S00-S09 (injuries to the head) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within S05, choose S05.4 (Penetrating wound of orbit with or without foreign body) only when documentation doesn't support a more specific option: injury of conjunctiva and corneal abrasion without foreign body (S05.0), contusion of eyeball and orbital tissues (S05.1), ocular laceration and rupture with prolapse or loss of intraocular tissue (S05.2), ocular laceration without prolapse or loss of intraocular tissue (S05.3), penetrating wound with foreign body of eyeball (S05.5), penetrating wound without foreign body of eyeball (S05.6), avulsion of eye (S05.7), other injuries of eye and orbit (S05.8) and 1 more.

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

The conditions in its Excludes2 note aren't part of S05.4, but may be coded alongside it if the patient has both: retained (old) foreign body following penetrating wound in orbit (H05.5-).

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