About coding middle ear injury

The ICD-10-CM code for middle ear injury is S09.30 (Unspecified injury of middle and inner ear).

Within S09.3, choose S09.30 (Unspecified injury of middle and inner ear) only when documentation doesn't support a more specific option: primary blast injury of ear (S09.31) and other specified injury of middle and inner ear (S09.39).

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.
