Injury to dorsal nerve root

This diagnosis code signifies trauma or damage specifically affecting the dorsal nerve root, which is responsible for transmitting sensory information from the body to the spinal cord. This injury can result in sensory deficits, pain, numbness, or paresthesia in the dermatome supplied by the affected nerve root.

This code is appropriate for documenting injuries directly impacting the sensory nerve roots emerging from the spinal cord. Documentation should clearly indicate a traumatic etiology, such as a fracture, dislocation, or direct impact, leading to damage of the dorsal root. It is used when the injury is to the nerve root itself, rather than the spinal cord or peripheral nerves.

• Differentiate from spinal cord injury (e.g., contusion, laceration) which involves the central nervous system.
• Ensure documentation specifies "dorsal nerve root" rather than just "nerve root" if possible, as some codes differentiate.
• Consider sequencing with external cause codes (E-codes) to fully describe the circumstances of the injury.
