Brown-Sequard syndrome at C8, sequela

This code describes the long-term effects or complications arising from a Brown-Sequard syndrome injury specifically affecting the C8 level of the cervical spinal cord. Brown-Sequard syndrome is characterized by hemisection of the spinal cord, resulting in ipsilateral motor paralysis and loss of proprioception, and contralateral loss of pain and temperature sensation below the level of the lesion. "Sequela" indicates that this code is used for residual conditions after the acute phase of the injury has passed.

Use this code when documenting a patient presenting with chronic neurological deficits directly attributable to a past Brown-Sequard syndrome injury at the C8 spinal cord level. Documentation should clearly state the C8 level involvement and indicate that the current condition is a residual effect, not an acute injury. This code is appropriate for follow-up visits addressing the ongoing management of these permanent neurological impairments.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated (e.g., hemiparesis, sensory deficits).
• Ensure documentation specifies "sequela" or "late effect" and clearly links the current symptoms to a prior Brown-Sequard injury at C8.
• Do not use this code for acute Brown-Sequard syndrome; instead, refer to codes in the S14.1- category for initial encounters.
