Final answer:
If a head injury is described as penetrating, but there is no skull penetration, the injury should be coded as a non-penetrating injury.
Step-by-step explanation:
If a head injury is described as penetrating, but there is no skull penetration, the injury should be coded as a non-penetrating injury. Penetrating head injuries involve an object that goes through the skull and enters the brain, causing damage. However, if there is no skull penetration, the injury does not meet the criteria for a penetrating injury.
