Complete lesion at C1 level of cervical spinal cord, init

This code signifies a complete transection or severe damage to the spinal cord at the C1 vertebral level, resulting in a total loss of motor and sensory function below that point. This type of injury typically leads to quadriplegia and respiratory compromise due to the high cervical involvement.

Apply this code for patients presenting with a newly diagnosed, acute spinal cord injury at the C1 level, where neurological examination confirms a complete lesion. Documentation should clearly state the C1 level and the completeness of the neurological deficit, often following traumatic events like motor vehicle accidents or falls.

• Ensure documentation specifies "complete" lesion; partial lesions at C1 are coded differently.
• Verify the encounter is "initial" for this specific injury; subsequent care uses different encounter characters.
• Always code any associated external cause of injury (e.g., fall, motor vehicle accident) in addition to this diagnosis.
