Brown-Sequard syndrome at C2, init

This code signifies a specific neurological disorder characterized by hemisection of the spinal cord at the C2 level, resulting in ipsilateral motor paralysis and loss of proprioception, and contralateral loss of pain and temperature sensation. It describes the initial presentation of this syndrome affecting the cervical spinal cord.

Apply this code for a patient presenting with new onset Brown-Sequard syndrome definitively localized to the C2 spinal cord segment. Documentation should clearly state the diagnosis, the C2 level involvement, and indicate that this is the first time the patient is being treated for this specific injury or condition.

• Ensure documentation explicitly states "Brown-Sequard syndrome" and the C2 level.
• The "A" in the seventh character indicates an initial encounter for active treatment. Subsequent encounters for healing or sequelae will require different seventh characters.
• Differentiate from other spinal cord injuries or syndromes that may present with similar symptoms but do not meet the full criteria for Brown-Sequard.
