Unsp opn wnd abd wall, right upper q w penet perit cav, sqla

This code signifies a long-term complication or late effect stemming from an open wound in the right upper quadrant of the abdominal wall that previously extended into the peritoneal cavity. The original injury is no longer acute, but its lasting consequences are now being addressed.

Apply this code when documenting the treatment or evaluation of a sequela (e.g., chronic pain, adhesion formation, hernia) directly attributable to a past penetrating open wound of the right upper abdominal wall. This is used when the initial injury has healed, but its residual effects are still present and require medical attention.

• Ensure documentation clearly links the current condition to a previous penetrating abdominal wound.
• This code requires a seventh character of 'S' for sequela, indicating a late effect.
• Do not use this code for the initial acute injury; a different seventh character would be appropriate for the initial encounter or subsequent care of the acute wound.
