Injury of axillary nerve, right arm, initial encounter

This code signifies damage to the axillary nerve in the right arm, which is crucial for shoulder movement and sensation over the deltoid. Such an injury can lead to weakness in shoulder abduction and external rotation, as well as numbness in the deltoid region.

Use this code for initial encounters involving a patient presenting with a newly diagnosed or treated injury to the right axillary nerve. This typically occurs following trauma such as shoulder dislocations, humeral fractures, or direct blows to the shoulder.

• Ensure documentation specifies the right arm and the initial phase of treatment for the injury.
• Distinguish from other nerve injuries in the shoulder/arm; the axillary nerve innervates the deltoid and teres minor.
• Consider additional codes for the underlying cause of the injury (e.g., fracture, dislocation) if applicable.
