Central cord syndrome at C4, init

This code signifies a specific type of incomplete spinal cord injury affecting the central gray matter at the C4 vertebral level. Patients typically present with greater motor weakness in the upper extremities than in the lower extremities, along with varying degrees of sensory loss and bladder dysfunction. It often results from hyperextension injuries in older individuals with pre-existing cervical spondylosis.

Apply this code when documentation clearly states a diagnosis of central cord syndrome localized to the C4 cervical level following an acute injury. This code is specifically for the initial encounter for this condition. Supporting documentation should detail the mechanism of injury, neurological deficits consistent with central cord syndrome, and the specific C4 level involvement.

• Ensure the documentation explicitly states "central cord syndrome" and the C4 level; do not assume based on symptoms alone.
• Verify the encounter is indeed the "initial encounter" for this specific injury; subsequent encounters will use different seventh characters.
• Distinguish from other incomplete spinal cord syndromes (e.g., anterior cord, Brown-Séquard) and complete spinal cord transections.
