ICD-10 code for forearm wound

The ICD-10-CM code for forearm wound is S51.80 (Unspecified open wound of forearm).

Within S51.8, choose S51.80 (Unspecified open wound of forearm) only when documentation doesn't support a more specific option: laceration without foreign body of forearm (S51.81), laceration with foreign body of forearm (S51.82), puncture wound without foreign body of forearm (S51.83), puncture wound with foreign body of forearm (S51.84) and open bite of forearm (S51.85).

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.
