About S09.20
S09.20 is the ICD-10-CM diagnosis code for traumatic rupture of unspecified ear drum. It belongs to category S09 (other and unspecified injuries 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 S09.2, choose S09.20 (unspecified ear drum) only when documentation doesn't support a more specific option: right ear drum (S09.21) and left ear drum (S09.22).
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.
