Contusion of bilateral back wall of thorax, init

This code signifies a bruise or contusion affecting both sides of the posterior chest wall. This injury typically results from blunt force trauma, causing damage to the underlying soft tissues without a break in the skin.

Apply this code when documentation clearly indicates a contusion to the back of the thorax, affecting both the left and right sides. This is appropriate for the initial treatment of such an injury, such as in an emergency department or initial physician visit.

• Ensure documentation specifies "bilateral" involvement of the back wall of the thorax.
• Confirm the encounter is the "initial encounter" for this specific injury.
• Distinguish from contusions of the anterior or lateral chest wall, which have different codes.
