Sprain of left sternoclavicular joint, initial encounter

This diagnosis code signifies a sprain, or ligamentous injury, affecting the sternoclavicular joint on the patient's left side. This joint connects the sternum (breastbone) to the clavicle (collarbone) and is crucial for shoulder girdle movement. The injury involves stretching or tearing of the ligaments supporting this joint.

Use this code for a patient presenting with a newly diagnosed sprain of the left sternoclavicular joint. This typically occurs following trauma, such as a direct blow to the shoulder or a fall onto an outstretched arm. It is appropriate for the initial evaluation and treatment of this specific injury.

• Ensure documentation clearly specifies the left sternoclavicular joint.
• Verify that the encounter is indeed the initial encounter for this specific injury.
• Look for details on the mechanism of injury and physical exam findings supporting a sprain.
