About S00.41

S00.41 is the ICD-10-CM diagnosis code for abrasion of ear. It belongs to category S00 (superficial injury 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 S00.4 (superficial injury of ear), S00.41 is specifically for abrasion of ear. Related codes cover unspecified superficial injury of ear (S00.40), Blister (nonthermal) of ear (S00.42), contusion of ear (S00.43), external constriction of ear (S00.44), superficial foreign body of ear (S00.45), insect bite (nonvenomous) of ear (S00.46) and other superficial bite of ear (S00.47).

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.
