Brown-Sequard syndrome at C5, init

This code signifies Brown-Sequard syndrome affecting the C5 level of the cervical spinal cord. This neurological condition results from hemisection of the spinal cord, leading to ipsilateral motor paralysis and loss of proprioception/vibration sensation, along with contralateral loss of pain and temperature sensation below the lesion.

Apply this code for patients presenting with the classic signs and symptoms of Brown-Sequard syndrome specifically localized to the C5 spinal cord segment. Documentation should clearly indicate the C5 level involvement and that this is the initial encounter for this specific injury or condition.

• Ensure documentation explicitly states "Brown-Sequard syndrome" and specifies the C5 level.
• Verify that this is indeed the "initial encounter" for the condition; subsequent encounters would use the appropriate seventh character.
• Differentiate from other spinal cord injuries or syndromes that do not present with the characteristic hemisection pattern.
