Contusion of left front wall of thorax, initial encounter

This code signifies a bruise or superficial injury to the anterior chest wall on the left side, resulting from direct trauma. It indicates damage to the soft tissues, such as muscle, fat, and skin, without an open wound or underlying fracture.

Apply this code for patients presenting with localized pain, swelling, and discoloration (ecchymosis) on the left front of the chest following an impact. This is appropriate for initial treatment of blunt force trauma to this specific area, such as from a fall, sports injury, or direct blow.

• Ensure documentation specifies the left front wall of the thorax.
• Verify the encounter is the initial treatment for this specific injury.
• Do not use if an open wound, fracture, or internal organ injury is also documented; more specific codes would apply.
