Central cord syndrome at C3, sequela

This code describes the long-term effects or complications arising from central cord syndrome specifically affecting the C3 level of the cervical spinal cord. Central cord syndrome typically involves greater motor impairment in the upper extremities than in the lower extremities, along with bladder dysfunction and variable sensory loss, resulting from damage to the central gray matter and innermost white matter tracts. 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 C3 level. This applies to patients presenting with ongoing motor weakness, sensory disturbances, or other neurological impairments in the distribution of C3, long after the initial injury. Documentation should clearly state the C3 level involvement and the chronic nature of the condition.

• Always ensure documentation specifies "sequela" or "late effect" to justify the 7th character 'S'.
• Code also any specific neurological deficits (e.g., muscle weakness, sensory loss) as secondary diagnoses.
• Do not use this code for acute central cord syndrome; refer to the acute injury codes for initial encounters.
