Injury of peripheral nerves of thorax, initial encounter

This code signifies damage to any of the peripheral nerves located within the thoracic region, such as intercostal nerves, phrenic nerves, or nerves of the brachial plexus as they exit the thoracic outlet. This injury can result from trauma, compression, or other external forces affecting these nerve pathways.

Use this code for the initial encounter of a patient presenting with an acute injury to the peripheral nerves of the chest wall or diaphragm. This includes cases like nerve damage from rib fractures, surgical trauma to thoracic nerves, or direct impact injuries affecting these structures.

• Ensure documentation clearly specifies "initial encounter" for the injury.
• Distinguish from central nervous system injuries or injuries to nerves of the upper extremity once they are outside the thoracic outlet.
• Look for specific nerve involvement (e.g., intercostal neuralgia post-trauma) to confirm peripheral nerve injury.
