S64.92Injury of unspecified nerve at wrist and hand level of left arm

S64.92 is the ICD-10-CM diagnosis code for injury of unspecified nerve at wrist and hand level of left arm. It belongs to category S64 (injury of nerves at wrist and hand level), block S60-S69 (injuries to the wrist, hand and fingers) 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 S64.9 (injury of unspecified nerve at wrist and hand level), S64.92 is specifically for injury of unspecified nerve at wrist and hand level of left arm. Related codes cover of unspecified arm (S64.90) and of right arm (S64.91).

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.
