About S89

S89 is the ICD-10-CM diagnosis code for other and unspecified injuries of lower leg. It belongs to block S80-S89 (injuries to the knee and lower leg) 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: S89.0 (tibia), S89.1 (tibia), S89.2 (fibula), S89.3 (fibula), S89.8 (leg) and S89.9 (leg).

The conditions in its Excludes2 note aren't part of S89, but may be coded alongside it if the patient has both: other and unspecified injuries of ankle and foot (S99.-).

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