About S00
S00 is the ICD-10-CM diagnosis code for superficial injury of head. It belongs to 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 8 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: S00.0 (scalp), S00.1 (area), S00.2 (area), S00.3 (nose), S00.4 (ear), S00.5 (cavity), S00.8 (head) and S00.9 (head).
Don't report S00 together with the conditions in its Excludes1 note: diffuse cerebral contusion (S06.2-), focal cerebral contusion (S06.3-), injury of eye and orbit (S05.-) and open wound of head (S01.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
