Injury of musculocutaneous nerve, left arm, initial encounter

📋Clinical Description

This code signifies damage to the musculocutaneous nerve in the patient's left arm, which can result in weakness or paralysis of the biceps and brachialis muscles, as well as sensory loss over the lateral forearm. The injury affects the nerve's ability to transmit signals for motor function and sensation.

🎯When to Use

Apply this code for initial treatment of acute trauma to the musculocutaneous nerve in the left arm, such as from a fracture, dislocation, or direct laceration. It is appropriate for the first encounter where the injury is diagnosed and active treatment is initiated.

💡Coding Tips

Ensure documentation specifies the left arm and the musculocutaneous nerve.
Verify the encounter is for the initial treatment of the injury; subsequent encounters will require a different seventh character.
Look for associated injuries, such as fractures (e.g., humerus), and code them separately.
