Question:
If a patient has a penetrating wound and an injury to an internal organ for example the liver, do I code both the open wound and the liver injury or just the liver injury?

Answer:
In ICD-10-CM, the comment below precedes each organ specific injury section:

Code also any associated open wound (S31.-)

So, the answers is yes, code the internal injury and the open wound.
