Brown-Sequard syndrome at T1, init

This code signifies a specific neurological condition, Brown-Sequard syndrome, which results from a hemisection (damage to one side) of the spinal cord. At the T1 level, this syndrome typically presents with ipsilateral (same side) paralysis and loss of proprioception/vibration, and contralateral (opposite side) loss of pain and temperature sensation below the lesion.

Use this code when documenting a new diagnosis of Brown-Sequard syndrome specifically affecting the T1 segment of the thoracic spinal cord. This applies to the initial evaluation and treatment of the patient for this condition, such as following a traumatic injury or acute compressive lesion.

• Ensure documentation clearly specifies the T1 level of the thoracic spinal cord.
• Verify that the encounter is indeed the "initial encounter" for this specific condition. Subsequent encounters would require a different 7th character.
• Look for clinical findings consistent with hemisection, such as asymmetrical motor and sensory deficits.
