S94.31Injury of cutaneous sensory nerve at ankle and foot level, right leg

S94.31 is the ICD-10-CM diagnosis code for injury of cutaneous sensory nerve at ankle and foot level, right leg. It belongs to category S94 (injury of nerves at ankle and foot level), 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 3 subcodes must be used instead.

Within S94.3 (injury of cutaneous sensory nerve at ankle and foot level), S94.31 is specifically for injury of cutaneous sensory nerve at ankle and foot level, right leg. Related codes cover unspecified leg (S94.30) and left leg (S94.32).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

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