Contusion of left upper arm, initial encounter

This code signifies a bruise or superficial injury to the soft tissues of the patient's left upper arm, resulting from blunt force trauma. It indicates damage to capillaries and other small blood vessels beneath the skin, without an open wound.

Apply this code when documenting a patient presenting with ecchymosis, tenderness, or swelling of the left upper arm due to an impact or fall. This is appropriate for the initial assessment and treatment of such an injury.

• Ensure documentation clearly specifies the left upper arm as the affected site.
• Confirm this is the patient's first encounter for this specific injury.
• Distinguish from abrasions or lacerations, which involve breaks in the skin.
