About S51.802
S51.802 is the ICD-10-CM diagnosis code for unspecified open wound of left forearm. It belongs to category S51 (open wound of elbow and forearm), 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 S51.80 (unspecified open wound of forearm), S51.802 is specifically for unspecified open wound of left forearm. Related codes cover right forearm (S51.801) and unspecified forearm (S51.809).
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.
