Brown-Sequard syndrome at C6, sequela

This code signifies the long-term neurological deficits resulting from a Brown-Sequard syndrome injury specifically affecting the C6 level of the cervical spinal cord. This syndrome is characterized by hemisection of the spinal cord, leading to ipsilateral motor paralysis and loss of proprioception/vibration sense, and contralateral loss of pain and temperature sensation below the level of the lesion. The "sequela" aspect indicates that these are residual effects after the acute phase of the injury has passed.

Use this code for patients presenting with chronic neurological symptoms consistent with Brown-Sequard syndrome that originated from a C6 cervical spinal cord injury. This applies when the initial injury occurred in the past and the patient is now being treated for the lasting consequences, such as persistent weakness, sensory deficits, or spasticity. It is appropriate for follow-up visits, rehabilitation, or ongoing management of these permanent impairments.

• Always ensure documentation clearly specifies "sequela" or "late effects" to justify using this code, rather than an acute injury code.
• Verify that the C6 level is explicitly documented as the site of the Brown-Sequard syndrome.
• Code any associated functional impairments or complications (e.g., spasticity, neurogenic bladder) separately, if applicable.
