Open wound of hip and thigh, with tendon involvement

This code signifies an open injury to the hip or thigh region where the wound extends deep enough to involve one or more tendons. This typically implies a laceration, puncture, or avulsion that has compromised the integrity of a tendon structure.

Use this code for traumatic open wounds of the hip or thigh clearly documented as involving tendon damage. Documentation should specify the anatomical site (hip or thigh) and explicitly state tendon involvement, often requiring surgical exploration or imaging confirmation.

• Always code the associated external cause of injury (E-code) to provide context for the wound.
• Distinguish carefully between tendon involvement and muscle involvement; separate codes exist for each.
• Ensure documentation specifies "open wound" and not just a contusion or closed injury.
