Lac w/o fb of abd wall, unsp q w penet perit cav, subs

This diagnosis code describes a cut or tear in the abdominal wall that extends into the peritoneal cavity, but does not involve a foreign object. The specific location on the abdomen is not documented, and this code is used for follow-up care after the initial injury.

Use this code for subsequent encounters when a patient is receiving ongoing treatment, monitoring, or recovery for a penetrating abdominal wall laceration. Examples include wound care, infection management, or follow-up appointments after surgical repair of the laceration. It is appropriate when the initial injury has already been treated.

• Ensure documentation specifies "subsequent encounter" for this injury.
• Verify that no foreign body was present in the laceration.
• Confirm the laceration penetrated the peritoneal cavity; superficial lacerations would use different codes.
