About S01.5

S01.5 is the ICD-10-CM diagnosis code for open wound of lip and oral cavity. It belongs to category S01 (open wound 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 6 subcodes must be used instead.

Within S01 (open wound of head), S01.5 is specifically for open wound of lip and oral cavity. Related codes cover scalp (S01.0), eyelid and periocular area (S01.1), nose (S01.2), ear (S01.3), cheek and temporomandibular area (S01.4), other parts of head (S01.8) and unspecified part of head (S01.9).

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 S01.5, but may be coded alongside it if the patient has both: tooth dislocation (S03.2) and tooth fracture (S02.5).

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