Open wound of foot except toe(s) alone, complicated

This code signifies an open wound on any part of the foot, excluding the toes, that has developed complications. Complications typically include delayed healing, infection, foreign body retention, or involvement of deeper structures like muscle or bone. It indicates a more severe or complex injury requiring additional medical attention.

Apply this code when documentation specifies an open wound of the foot (excluding toes) with an explicit mention of complications such as infection, foreign body, or delayed healing. This is appropriate for injuries like lacerations, punctures, or avulsions that have progressed beyond a simple, uncomplicated state. Supporting documentation should clearly detail the nature of the complication.

• Differentiate from uncomplicated open wounds of the foot (891.x) or open wounds of the toe(s) (893.x).
• Ensure the medical record explicitly states a complication; "complicated" is not assumed.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity or complication of another condition.
