S46.0Injury of muscle(s) and tendon(s) of the rotator cuff of shoulder

S46.0 is the ICD-10-CM diagnosis code for injury of muscle(s) and tendon(s) of the rotator cuff of shoulder. 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 4 subcodes must be used instead.

Within S46 (injury of muscle, fascia and tendon at shoulder and upper arm level), S46.0 is specifically for injury of muscle(s) and tendon(s) of the rotator cuff of shoulder. Related codes cover muscle, fascia and tendon of long head of biceps (S46.1), muscle, fascia and tendon of other parts of biceps (S46.2), muscle, fascia and tendon of triceps (S46.3), other muscles, fascia and tendons at shoulder and upper arm level (S46.8) and unspecified muscle, fascia and tendon at shoulder and upper arm level (S46.9).

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.
