About S42

S42 is the ICD-10-CM diagnosis code for fracture 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S42.0 (clavicle), S42.1 (scapula), S42.2 (humerus), S42.3 (humerus), S42.4 (humerus) and S42.9 (unspecified).

Don't report S42 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 S42, but may be coded alongside it if the patient has both: periprosthetic fracture around internal prosthetic shoulder joint (M97.3).

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