Disrupt/dehisc closr int op (surg) wnd abd wl msl/fasc, sqla

This code signifies a late complication where a previously closed surgical incision in the abdominal wall muscles or fascia has separated or burst open. This disruption can occur days, weeks, or even months after the initial operation, indicating a failure of the wound to heal properly.

Apply this code when documenting a patient presenting with a chronic or long-term issue related to the breakdown of an abdominal surgical wound closure. This includes cases where a patient returns for repair of a dehisced fascial or muscle layer from a prior abdominal surgery. The "S" seventh character indicates that this is a sequela, meaning it's a late effect of the initial problem.

• Always assign an additional code to specify the underlying cause of the initial operation, if known and relevant.
• Ensure the documentation clearly indicates the abdominal wall muscle or fascia as the affected site.
• The "S" seventh character is crucial for indicating a sequela; do not use for acute dehiscence.
