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

This code signifies a penetrating injury to the left flank of the abdomen caused by a sharp object, where a foreign body remains embedded in the tissue. Importantly, this injury does not extend into the abdominal cavity itself, meaning the peritoneum remains intact.

Apply this code for patients presenting with a puncture wound to the left flank that has introduced a foreign object, such as a splinter, glass shard, or metal fragment, but imaging or exploration confirms no peritoneal involvement. This is appropriate for the initial assessment and treatment of such an injury.

• Ensure documentation explicitly states "left flank" and "without penetration into peritoneal cavity."
• Confirm the presence of a retained foreign body; otherwise, a different code for puncture wound without foreign body would be appropriate.
• The "A" at the end indicates an initial encounter for this injury. Subsequent care would require a different seventh character.
