S49.91Unspecified injury of right shoulder and upper arm

S49.91 is the ICD-10-CM diagnosis code for unspecified injury of right shoulder and upper arm. It belongs to category S49 (other and unspecified injuries of shoulder and upper arm), 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 S49.9 (unspecified injury of shoulder and upper arm), S49.91 is specifically for unspecified injury of right shoulder and upper arm. Related codes cover unspecified arm (S49.90) and left shoulder and upper arm (S49.92).

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.
