ICD-10 code for arm upper wound

The ICD-10-CM code for arm upper wound is S41.10 (Unspecified open wound of upper arm).

Within S41.1, choose S41.10 (Unspecified open wound of upper arm) only when documentation doesn't support a more specific option: laceration without foreign body of upper arm (S41.11), laceration with foreign body of upper arm (S41.12), puncture wound without foreign body of upper arm (S41.13), puncture wound with foreign body of upper arm (S41.14) and open bite of upper arm (S41.15).

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.
