Central cord syndrome at C1, sequela

This code signifies the long-term effects or complications arising from central cord syndrome specifically affecting the C1 level of the cervical spinal cord. Central cord syndrome typically involves greater motor impairment in the upper extremities than the lower extremities, along with bladder dysfunction and sensory loss below the level of injury. The "sequela" designation indicates that this code is used for residual conditions after the acute phase of the injury has passed.

Use this code when documenting the chronic or residual neurological deficits directly attributable to a past central cord syndrome injury at the C1 spinal level. This is appropriate for follow-up encounters where the patient is being treated for the lasting effects, such as persistent weakness, sensory changes, or spasticity. Documentation should clearly state the C1 level involvement and indicate that the condition is a sequela.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated (e.g., spasticity, paralysis).
• Do not use this code for acute central cord syndrome; specific acute injury codes (e.g., S14.121A, S14.121D) are for initial or subsequent encounters during the active treatment phase.
• Ensure the medical record explicitly states "sequela" or describes the condition as a chronic, residual effect of a past central cord injury at C1.
