Open bite of abd wall, right lower q w penet perit cav, sqla

This code signifies a past injury to the right lower abdominal wall that involved an open wound and extended into the peritoneal cavity. The "sequela" indicates that this code is used to report a current condition or complication resulting from that original injury, rather than the acute injury itself.

This code is appropriate when a patient presents with a long-term consequence, such as an adhesion, chronic pain, or a fistula, directly attributable to a previously sustained open bite wound of the right lower abdominal wall that penetrated the peritoneal cavity. It should be used for follow-up care or treatment of these residual effects, not for the initial injury.

• Always assign an additional code to specify the nature of the sequela (e.g., K66.0 for peritoneal adhesions).
• Ensure documentation clearly links the current condition to the historical open bite injury with peritoneal penetration.
• Do not use this code for acute injuries; instead, refer to the appropriate acute injury code from the S31.653 series.
