Contusion of middle front wall of thorax, initial encounter

This code signifies a bruise or superficial injury to the central anterior chest wall, specifically involving the sternum and surrounding soft tissues. It indicates damage to capillaries and other small blood vessels beneath the skin, resulting in discoloration and swelling, without an open wound.

Apply this code for patients presenting with a closed injury to the sternal area or the region directly over the breastbone, such as from a direct impact or blunt trauma. This is appropriate for the initial visit for this specific injury.

• Ensure documentation specifies the "middle front wall of thorax" to differentiate from lateral or posterior chest wall contusions.
• Confirm this is the patient's first encounter for this specific injury; subsequent encounters will require a different seventh character.
• Do not use for open wounds, fractures, or internal organ injuries, even if co-occurring; these require separate, more specific codes.
