It belongs to category S46 (injury of muscle, fascia and tendon at shoulder and upper arm level), block S40-S49 (injuries to the shoulder and upper arm) 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 S46.99 (other injury of unspecified muscle, fascia and tendon at shoulder and upper arm level), S46.992 is specifically for other injury of unspecified muscle, fascia and tendon at shoulder and upper arm level, left arm. Related codes cover right arm (S46.991) and unspecified arm (S46.999).

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.
