Fracture of manubrium, initial encounter for closed fracture

This diagnosis code signifies a break in the manubrium, the upper part of the sternum, that has not broken through the skin. It indicates the initial treatment phase for this type of closed fracture.

Apply this code for patients presenting with a newly diagnosed, non-compound fracture of the manubrium, such as from direct blunt force trauma to the chest. This is appropriate for the initial hospital visit or first encounter for treatment of the injury.

• Ensure documentation specifies a closed fracture and the manubrium as the fracture site.
• The "A" seventh character indicates an initial encounter for active treatment.
• Do not use for open fractures or subsequent encounters for healing or sequelae.
