About S01.331

S01.331 is the ICD-10-CM diagnosis code for puncture wound without foreign body of right 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 S01.33 (puncture wound without foreign body of ear), S01.331 is specifically for puncture wound without foreign body of right ear. Related codes cover left ear (S01.332) and unspecified ear (S01.339).

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.
