About S94

S94 is the ICD-10-CM diagnosis code for injury of nerves at ankle and foot level. It belongs to block S90-S99 (injuries to the ankle and foot) 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: S94.0 (nerve), S94.1 (nerve), S94.2 (level), S94.3 (level), S94.8 (level) and S94.9 (level).

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