About S52

S52 is the ICD-10-CM diagnosis code for fracture of 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 7 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S52.0 (ulna), S52.1 (radius), S52.2 (ulna), S52.3 (radius), S52.5 (radius), S52.6 (ulna) and S52.9 (forearm).

Don't report S52 together with the conditions in its Excludes1 note: traumatic amputation of forearm (S58.-).

The conditions in its Excludes2 note aren't part of S52, but may be coded alongside it if the patient has both: fracture at wrist and hand level (S62.-) and periprosthetic fracture around internal prosthetic elbow joint (M97.4).

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