About S50

S50 is the ICD-10-CM diagnosis code for superficial injury of elbow and forearm. It belongs to block S50-S59 (injuries to the elbow and forearm) 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 5 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S50.0 (elbow), S50.1 (forearm), S50.3 (elbow), S50.8 (forearm) and S50.9 (forearm).

The conditions in its Excludes2 note aren't part of S50, but may be coded alongside it if the patient has both: superficial injury of wrist and hand (S60.-).

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