Lac w/o fb of abd wall, l flank with penet perit cav, init

This code signifies a cut or tear on the left side of the abdominal wall, specifically the flank region, that has extended through all layers and entered the peritoneal cavity. This injury does not involve any foreign objects embedded in the wound. It represents the initial treatment for such a laceration.

Use this code for patients presenting with a penetrating injury to the left flank that has breached the peritoneum, such as from a stab wound or deep laceration. This code is appropriate when there is no foreign body documented within the wound itself. It should be assigned during the initial phase of care for this specific injury.

• Confirm documentation explicitly states "left flank" and "penetration into peritoneal cavity."
• Ensure there is no mention of a foreign body in the wound to differentiate from other laceration codes.
• Verify this is the initial encounter for treatment of this specific injury; subsequent encounters will require different seventh characters.
