Knife, sword or dagger entering via natural orifice, init

This code signifies an injury where a sharp, pointed object like a knife, sword, or dagger has penetrated the body through a natural opening, such as the mouth, nose, ear, anus, urethra, or vagina. The injury is acute and represents the first time the patient is receiving care for this specific incident.

Apply this code when documenting an initial encounter for a patient presenting with a stab wound where the weapon entered via a natural orifice. Examples include a knife inserted into the mouth, a dagger penetrating the ear canal, or a sword entering the rectum. This code is appropriate for the initial treatment phase of such an injury.

• Always assign an external cause code (V00-Y99) to describe the circumstances of the injury.
• Do not use this code for objects entering through an open wound or direct penetration of the skin.
• Ensure documentation clearly specifies the type of sharp object and the natural orifice involved.
