Pnctr w/o fb of abd wall, r upper q w penet perit cav, init

This code signifies a sharp, pointed object has pierced the skin and underlying tissues of the right upper abdomen, extending into the peritoneal cavity, without leaving any foreign material behind. This type of injury carries a significant risk of internal organ damage and infection due to the breach of the sterile peritoneal space.

Apply this code for patients presenting with a stab wound or other penetrating injury to the right upper quadrant of the abdomen, where surgical exploration or imaging confirms entry into the peritoneal cavity. This is appropriate for the initial treatment of such an injury, prior to any definitive surgical repair.

• Ensure documentation clearly specifies "right upper quadrant" and "penetration into peritoneal cavity."
• Distinguish from superficial wounds or those without peritoneal penetration.
• Confirm the absence of a retained foreign body; a different code would be used if one is present.
