Brown-Sequard syndrome at C7, init

This code signifies Brown-Sequard syndrome affecting the C7 level of the cervical spinal cord. This rare neurological condition results from 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.

Apply this code for the initial encounter of a patient presenting with documented Brown-Sequard syndrome specifically localized to the C7 spinal cord segment. Documentation should clearly indicate the C7 level and the characteristic neurological deficits consistent with this syndrome.

• Ensure documentation explicitly states "C7 level" for precise anatomical specificity.
• Verify this is the "initial encounter" for the condition; subsequent encounters will require a different seventh character.
• Differentiate from other spinal cord lesions or incomplete spinal cord syndromes that do not present with the classic Brown-Sequard pattern.
