Pnctr of abd wall w/o fb, unsp q w/o penet perit cav, init

This code signifies a superficial piercing injury to the abdominal wall that does not involve an object remaining in the wound and has not breached the peritoneal cavity. The exact location of the puncture on the abdomen is not specified.

Apply this code for initial encounters where a patient presents with a simple puncture wound to the abdomen, such as from a needle stick or a minor sharp object, and there is no evidence of a retained foreign body or deeper organ involvement. This is appropriate when the specific abdominal quadrant is not documented.

• Ensure documentation explicitly states "without foreign body" and "without penetration into peritoneal cavity."
• If a foreign body is present, a different code from the S31.14- or S31.15- series would be more appropriate.
• If the specific abdominal quadrant is known, use a more precise code (e.g., S31.130A-S31.137A).
