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

This code signifies a partial or complete separation of the surgical incision layers involving the abdominal wall muscle or fascia, occurring after the initial operative encounter. It indicates a failure of the wound closure to remain intact at the deeper tissue levels.

Use this code when documenting follow-up care for a patient experiencing a breakdown of their abdominal wall muscle or fascial closure after a prior surgery. This includes scenarios where the wound has reopened or the layers have separated, requiring further medical attention or intervention.

• Ensure documentation clearly specifies the abdominal wall muscle or fascia as the affected site of disruption.
• Confirm this is a "subsequent encounter" for the complication, not the initial treatment or diagnosis.
• Distinguish from superficial dehiscence (skin/subcutaneous tissue only) which would be coded differently.
