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

This code describes a puncture wound to the left flank of the abdominal wall that includes a foreign body, but importantly, does not extend into the peritoneal cavity. The "S" at the end indicates that this is a sequela, meaning it represents a complication or condition arising as a direct result of the initial injury, occurring after the acute phase has passed.

Use this code when documenting a long-term effect or complication stemming from a past puncture wound to the left flank with a retained foreign body, where the initial injury did not penetrate the peritoneum. Examples include chronic pain, infection, or scar tissue formation related to the foreign body, presenting after the initial wound has healed.

• Ensure documentation clearly states the wound is to the left flank and that a foreign body is present.
• Verify that the medical record explicitly rules out penetration into the peritoneal cavity.
• The "S" character mandates that this code is used for conditions that are a sequela of the original injury, not for the initial acute encounter.
