About S59

S59 is the ICD-10-CM diagnosis code for other and unspecified injuries 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: S59.0 (ulna), S59.1 (radius), S59.2 (radius), S59.8 (forearm) and S59.9 (forearm).

The conditions in its Excludes2 note aren't part of S59, but may be coded alongside it if the patient has both: other and unspecified injuries of wrist and hand (S69.-).

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