Infection of obstetric surgical wound, deep incisional site

This code signifies a deep incisional infection following an obstetric surgical procedure, such as a Cesarean section or other postpartum surgical intervention. It indicates that the infection extends beyond the skin and subcutaneous tissue, involving deeper fascial and muscle layers. This condition typically presents with signs of inflammation, purulent drainage, and systemic symptoms.

Apply this code when documentation clearly indicates a deep incisional surgical site infection (SSI) occurring after an obstetric procedure. This includes infections affecting the fascia and/or muscle layers. Supporting documentation should specify the depth of the infection and its association with a recent obstetric surgery.

• Differentiate from superficial incisional infections (O86.01) and organ/space infections (O86.03).
• Ensure the documentation specifies "deep incisional" to justify this code.
• Sequence this code as a secondary diagnosis when the primary reason for admission or encounter is related to the management of this infection.
