Open bite of abd wall, l upr q w penet perit cav, sequela

This code describes the long-term effects or complications arising from an open wound in the upper left abdomen that extended into the peritoneal cavity. This indicates a previous injury where the abdominal wall was breached, and the abdominal lining was penetrated, with the current encounter addressing a residual condition.

Use this code when documenting a patient presenting with a sequela (e.g., chronic pain, adhesion formation, fistula) directly attributable to a past open bite injury of the left upper abdominal wall that involved penetration of the peritoneal cavity. This code is appropriate for follow-up encounters addressing the late effects of such an injury, not the initial acute injury.

• Assign this code as a secondary diagnosis when the sequela is the primary reason for the encounter, or as a primary diagnosis if the sequela itself is the focus of treatment.
• Ensure documentation clearly links the current condition to the previous open bite injury with peritoneal penetration.
• Do not use for acute injuries; instead, refer to the appropriate acute injury codes for the initial encounter.
