About S01.352

S01.352 is the ICD-10-CM diagnosis code for open bite of left ear. 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 3 subcodes must be used instead.

Within S01.35 (open bite of ear), S01.352 is specifically for open bite of left ear. Related codes cover right ear (S01.351) and unspecified ear (S01.359).

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.

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