S54.2Injury of radial nerve at forearm level

S54.2 is the ICD-10-CM diagnosis code for injury of radial nerve at forearm level. It belongs to category S54 (injury of nerves at forearm level), 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 3 subcodes must be used instead.

Within S54 (injury of nerves at forearm level), S54.2 is specifically for injury of radial nerve at forearm level. Related codes cover ulnar nerve at forearm level (S54.0), median nerve at forearm level (S54.1), cutaneous sensory nerve at forearm level (S54.3), other nerves at forearm level (S54.8) and unspecified nerve at forearm level (S54.9).

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.
