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

This code describes a puncture injury to the abdominal wall in an unspecified flank region, where a foreign object has entered the tissue but has not breached the peritoneal cavity. It signifies the initial treatment for such an injury.

Apply this code when a patient presents with a stab wound, impalement, or other penetrating injury to the flank, and imaging or clinical assessment confirms the foreign body is present within the abdominal wall musculature or subcutaneous tissue without evidence of peritoneal involvement. This is appropriate for the first encounter for this specific injury.

• Ensure documentation clearly states the foreign body is present and that there is no penetration into the peritoneal cavity.
• Specify the flank (left or right) if known; otherwise, "unspecified" is appropriate.
• Use a subsequent encounter code (S31.14AD, S31.14AS) for follow-up care after the initial treatment.
