About S01
S01 is the ICD-10-CM diagnosis code for open wound 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: S01.0 (scalp), S01.1 (area), S01.2 (nose), S01.3 (ear), S01.4 (area), S01.5 (cavity), S01.8 (head) and S01.9 (head).
Don't report S01 together with the conditions in its Excludes1 note: open skull fracture (S02.- with 7th character B).
The conditions in its Excludes2 note aren't part of S01, but may be coded alongside it if the patient has both: injury of eye and orbit (S05.-) and traumatic amputation of part of head (S08.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
