Sternal manubrial dissociation, init for opn fx

This code signifies a complete separation of the manubrium from the body of the sternum, where the fracture is open, meaning there is a break in the skin or mucous membrane leading to the fracture site. This injury often results from high-impact trauma and can be associated with significant underlying organ damage.

Apply this code for patients presenting with a newly diagnosed sternal manubrial dissociation that involves an open fracture. This would typically be used for the initial treatment of the injury, such as in an emergency department or during the first surgical intervention.

• Always confirm the "open" nature of the fracture documented by the provider.
• Ensure the encounter is the "initial encounter" for this specific injury. Subsequent care would require a different seventh character.
• Look for documentation of the mechanism of injury and any associated internal organ damage, which may require additional coding.
