Unsp opn wnd abd wall, r upper q w/o penet perit cav, init

This code signifies an open wound, such as a laceration or puncture, located on the right upper quadrant of the abdomen. Importantly, the wound does not extend into the peritoneal cavity, meaning the internal abdominal organs are not exposed or directly injured. This indicates a superficial or partial-thickness injury to the abdominal wall.

Use this code for initial encounters with patients presenting with an open wound to the right upper abdomen where there is no evidence of peritoneal penetration. This would include scenarios like a superficial stab wound, a deep laceration from a fall, or a traumatic abrasion that has broken the skin, as long as imaging or physical exam confirms no deeper involvement.

• Ensure documentation explicitly states "right upper quadrant" and "without penetration into peritoneal cavity."
• Verify this is the initial encounter for the injury; subsequent care would use a different seventh character.
• Look for associated codes for foreign bodies, infections, or other complications if present.
