Cervicobrachial syndrome

Cervicobrachial syndrome describes a constellation of symptoms including pain, numbness, tingling, or weakness that originates in the cervical spine and radiates down into the arm. This condition typically results from nerve root compression or irritation in the neck, affecting the brachial plexus. It is a general term for symptoms affecting both the neck and arm.

This code is appropriate when documentation indicates a diagnosis of cervicobrachial syndrome without further specification of the underlying cause. It should be used when the physician explicitly states this diagnosis, and the symptoms involve both the cervical region and the ipsilateral upper extremity. Avoid using this code if a more specific diagnosis, such as a cervical disc disorder, is documented.

• Do not use this code if the documentation specifies a cervical disc disorder (e.g., M50.-) as the etiology.
• Differentiate from thoracic outlet syndrome (G54.0), which involves compression of neurovascular structures in the thoracic outlet, not primarily the cervical spine.
• Ensure the physician's documentation clearly links symptoms in the neck and arm to support this diagnosis.
