Brown-Sequard syndrome at C6, init

This code signifies a rare neurological condition, Brown-Sequard syndrome, specifically affecting the C6 level of the cervical spinal cord. It results from a hemisection of the spinal cord, leading to ipsilateral motor paralysis and loss of proprioception, and contralateral loss of pain and temperature sensation below the lesion.

Use this code for a patient presenting with the classic signs and symptoms of Brown-Sequard syndrome localized to the C6 spinal cord segment, such as weakness and loss of vibratory sense on one side, and loss of pain and temperature sensation on the opposite side, following an acute injury. Documentation should clearly specify the C6 level involvement and indicate this is the initial presentation or treatment for the condition.

• Ensure documentation explicitly states "Brown-Sequard syndrome" and the specific C6 level of involvement.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
• Distinguish from other spinal cord injuries (e.g., central cord syndrome) that may present with similar but distinct neurological deficits.
