Pnctr w/o fb of abd wl, periumb rgn w penet perit cav, init

This code signifies a penetrating injury to the abdominal wall in the periumbilical area, specifically a puncture wound that has breached the peritoneum. It indicates that no foreign object is currently embedded in the wound. This is an initial presentation of the injury.

Use this code for patients presenting with a fresh stab wound or similar sharp object injury to the belly button region that is confirmed to have entered the abdominal cavity. This applies when imaging or surgical exploration reveals peritoneal penetration without a retained foreign body.

• Ensure documentation explicitly states "periumbilical region" and "penetration into peritoneal cavity."
• Confirm the absence of a foreign body; if present, a different code is required.
• The "A" in the seventh character indicates an initial encounter for this injury.
