What This Code Means

Complete paralysis of all four limbs resulting from injury to the upper cervical spinal cord (C1-C4 vertebrae level), with total loss of motor and sensory function below the injury.

Coding Tips

• •Complete quadriplegia at C1-C4 level typically results in the most severe functional impairment and may require ventilator support
• •Ensure documentation specifies both the C1-C4 level and that the paralysis is complete before assigning this code

Clinical Significance

Complete quadriplegia at the C1-C4 level represents the most severe form of spinal cord injury with total loss of function in all four extremities and typically requiring mechanical ventilation. These patients are entirely dependent for all activities of daily living and are at extreme risk for respiratory failure, pressure injuries, autonomic dysreflexia, and numerous other complications. This is one of the most resource-intensive conditions in all of medicine.

Documentation Requirements

• ✓Documentation of complete quadriplegia specifying C1-C4 cervical level
• ✓Verification of complete loss of motor and sensory function below the injury
• ✓Ventilator dependency status if applicable
• ✓Underlying etiology (trauma, tumor, vascular, etc.)
• ✓Respiratory management plan
• ✓Full care dependency documentation
• ✓Bladder/bowel management approach
• ✓Skin integrity protocol
• ✓Active specialist care plan
