Open wound of hand except finger(s) alone, complicated

This code signifies an open injury to the hand, excluding the fingers, that involves additional complexities beyond a simple laceration. Such complications might include significant contamination, foreign body presence, tissue loss, or involvement of deeper structures like tendons, nerves, or blood vessels. It indicates a wound requiring more extensive medical intervention than an uncomplicated open wound.

Use this code when documentation clearly states an open wound of the hand (palm, dorsum, wrist area) and specifies a complicating factor. Examples include a deep laceration with tendon exposure, a crush injury with significant tissue devitalization, or a puncture wound with embedded debris. The physician's notes should detail the nature of the complication.

• Ensure the documentation explicitly states "complicated" or describes a complicating factor; otherwise, consider an uncomplicated open wound code.
• Distinguish carefully between hand wounds and finger wounds; this code specifically excludes fingers.
• Look for documentation of debridement, foreign body removal, or repair of deeper structures as indicators of a complicated wound.
