S41Open wound of shoulder and upper arm

S41 is the ICD-10-CM diagnosis code for open wound of shoulder and upper arm. 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 2 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S41.0 (shoulder) and S41.1 (arm).

Don't report S41 together with the conditions in its Excludes1 note: traumatic amputation of shoulder and upper arm (S48.-).

The conditions in its Excludes2 note aren't part of S41, but may be coded alongside it if the patient has both: open fracture of shoulder and upper arm (S42.- with 7th character B or C).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
