About coding ear injury
The ICD-10-CM code for ear injury is S09.91 (Unspecified injury of ear). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on S09.91.
Within S09.9 (unspecified injury of face and head), S09.91 is specifically for unspecified injury of ear. Related codes cover head (S09.90), nose (S09.92) and face (S09.93).
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.
