Clinical InformationClinical

  • Thoracic Outlet Syndrome

    a neurovascular syndrome associated with compression of the brachial plexus; subclavian artery; and subclavian vein at the superior thoracic outlet. this may result from a variety of anomalies such as a cervical rib, anomalous fascial bands, and abnormalities of the origin or insertion of the anterior or medial scalene muscles. clinical features may include pain in the shoulder and neck region which radiates into the arm, paresis or paralysis of brachial plexus innervated muscles, paresthesia, loss of sensation, reduction of arterial pulses in the affected extremity, ischemia, and edema. (adams et al., principles of neurology, 6th ed, pp214-5).

  • Thoracic Outlet Syndrome

    a syndrome resulting from the compression of the blood vessels or nerves in the space between the clavicle and first rib (thoracic outlet). it is caused by car accident injuries or repetitive job or sport-related injuries. signs and symptoms include pain in the shoulders and neck, numbness in the fingers, and weakening grip.

Patient EducationClinical

Brachial Plexus Injuries

The brachial plexus is a network of nerves that sends signals from the spine to the shoulder, arm, and hand. Damage to the brachial plexus can cause symptoms such as:

Questions About G54.0Overview

Is G54.0 (Nerve root and plexus disorders) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report brachial plexus disorders on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What is the ICD-9 equivalent of G54.0?

Under the General Equivalence Mappings, brachial plexus disorders converts to ICD-9-CM 353.0 (brachial plexus lesions). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
