About S46
S46 is the ICD-10-CM diagnosis code for injury of muscle, fascia and tendon at shoulder and upper arm level. It belongs to 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 6 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: S46.0 (shoulder), S46.1 (biceps), S46.2 (biceps), S46.3 (triceps), S46.8 (level) and S46.9 (level).
The conditions in its Excludes2 note aren't part of S46, but may be coded alongside it if the patient has both: injury of muscle, fascia and tendon at elbow (S56.-) and sprain of joints and ligaments of shoulder girdle (S43.9).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
