Brown-Sequard syndrome at T2-T6, sequela

This code signifies a long-term neurological deficit resulting from Brown-Sequard syndrome affecting the T2-T6 segment of the thoracic spinal cord. This syndrome is characterized by hemisection of the spinal cord, leading to ipsilateral motor paralysis and loss of proprioception, and contralateral loss of pain and temperature sensation below the level of the lesion. The "sequela" designation indicates that the acute injury has resolved, but the patient continues to experience residual effects.

Use this code for patients presenting with chronic neurological deficits consistent with a past Brown-Sequard injury to the T2-T6 thoracic spinal cord. This would apply to follow-up encounters for ongoing management of motor weakness, sensory disturbances, or other long-term complications directly attributable to the original spinal cord damage. It is appropriate when the initial injury is no longer active.

• Ensure documentation clearly states the specific spinal cord level (T2-T6) and the "sequela" nature of the condition.
• Do not use this code for acute Brown-Sequard syndrome; a different code from the S24.14x category would be appropriate for the initial encounter.
• Always code any associated neurological deficits (e.g., specific motor weakness, sensory loss) separately, if applicable, to fully capture the patient's condition.
