S05.1Contusion of eyeball and orbital tissues

S05.1 is the ICD-10-CM diagnosis code for contusion of eyeball and orbital tissues. 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 (injury of eye and orbit), S05.1 is specifically for contusion of eyeball and orbital tissues. Related codes cover injury of conjunctiva and corneal abrasion without foreign body (S05.0), 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 of orbit with or without foreign body (S05.4), 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 S05.1, but may be coded alongside it if the patient has both: black eye NOS (S00.1) and contusion of eyelid and periocular area (S00.1).

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