0.000What This Code Means
Partial paralysis of all four limbs resulting from injury to the upper cervical spinal cord (C1-C4 vertebrae level), with some preservation of motor or sensory function below the injury.
Coding Tips
- •Incomplete quadriplegia at C1-C4 indicates some neurological function is preserved, which affects rehabilitation potential and prognosis
- •Verify documentation confirms both the C1-C4 level and incomplete status of the paralysis
Clinical Significance
Incomplete quadriplegia at the C1-C4 level indicates some preservation of neurological function despite high cervical spinal cord involvement. While still extremely disabling, these patients may retain some voluntary movement or sensation, which significantly affects rehabilitation potential and functional prognosis. The distinction from complete quadriplegia at this level is clinically critical as it impacts ventilator weaning potential and long-term independence goals.
Documentation Requirements
- ✓Documentation specifying C1-C4 level injury with incomplete paralysis
- ✓Description of preserved motor or sensory function
- ✓Neurological level and completeness assessment (ASIA scale if available)
- ✓Underlying etiology
- ✓Respiratory status and ventilator needs
- ✓Functional assessment and rehabilitation potential
- ✓Active management plan
- ✓Equipment and support needs
