S00.1Contusion of eyelid and periocular area

S00.1 is the ICD-10-CM diagnosis code for contusion of eyelid and periocular area. It belongs to category S00 (superficial injury of head), 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 S00 (superficial injury of head), S00.1 is specifically for contusion of eyelid and periocular area. Related codes cover superficial injury of scalp (S00.0), other and unspecified superficial injuries of eyelid and periocular area (S00.2), superficial injury of nose (S00.3), superficial injury of ear (S00.4), superficial injury of lip and oral cavity (S00.5), superficial injury of other parts of head (S00.8) and superficial injury of unspecified part of head (S00.9).

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 S00.1, but may be coded alongside it if the patient has both: contusion of eyeball and orbital tissues (S05.1-).

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