About S09.19

S09.19 is the ICD-10-CM diagnosis code for other specified injury of muscle and tendon of head. 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 S09.1, choose S09.19 (Other specified injury of muscle and tendon of head) only when documentation doesn't support a more specific option: unspecified injury of muscle and tendon of head (S09.10), strain of muscle and tendon of head (S09.11) and laceration of muscle and tendon of head (S09.12).

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.
