Contusion of right back wall of thorax, initial encounter

This code signifies a bruise or superficial injury to the posterior aspect of the right chest wall, typically resulting from blunt force trauma. It indicates damage to the soft tissues, such as muscle, fat, and skin, without an open wound or fracture.

Apply this code for patients presenting with localized pain, tenderness, swelling, and discoloration (ecchymosis) on the right side of their back, at the level of the thorax, following an acute injury. This is appropriate for the initial assessment and treatment of such an injury.

• Ensure documentation specifies the right side of the thorax and confirms it's a contusion, not an open wound or deeper injury.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Do not use this code if there is an associated fracture of the ribs or vertebrae; a more specific fracture code would be required.
