S14.144D Brown-Sequard syndrome at C4 level of cervical spinal cord, subsequent encounter

Name of the Condition

• Brown-Sequard syndrome at C4 level of cervical spinal cord, subsequent encounter

Summary

This condition is a specific type of spinal cord injury characterized by a hemisection (partial damage to one side) of the cervical spinal cord at the C4 level, occurring during a subsequent encounter. It results in a distinct pattern of neurological deficits, including ipsilateral (same side) motor weakness or paralysis and loss of proprioception (position sense) below the injury level, combined with contralateral (opposite side) loss of pain and temperature sensation. The C4 level is part of the cervical spinal cord, which transmits signals between the brain and the upper body, so injuries here can affect motor, sensory, or autonomic functions.

Causes

Brown-Sequard syndrome at the C4 level is typically caused by traumatic events, such as penetrating injuries (e.g., stab wounds or gunshot wounds) that damage one side of the spinal cord. Other traumatic causes include fractures, dislocations, or severe compression of the cervical spine. Non-traumatic causes, such as tumors, infections, or inflammatory conditions (e.g., multiple sclerosis), may also lead to this syndrome by affecting one side of the spinal cord.

Risk Factors

• Participation in high-impact sports or activities with a risk of neck injury.
• Occupations involving heavy lifting or repetitive neck strain.
• Conditions that weaken bone or tissue.

Symptoms

• Ipsilateral (same side) motor weakness or paralysis below the injury level.
• Loss of proprioception (position sense) on the same side as the injury.
• Contralateral (opposite side) loss of pain and temperature sensation below the injury level.
• Possible autonomic dysfunction, such as changes in blood pressure or bladder control.

Diagnosis

Diagnosis involves a thorough neurological examination to assess motor, sensory, and autonomic function. Imaging studies, such as MRI or CT scans, are used to identify the location and extent of spinal cord damage. Additional tests may include electromyography (EMG) or nerve conduction studies to evaluate nerve function.

Treatment Options

Treatment focuses on stabilizing the injury, managing symptoms, and preventing complications. This may include immobilization of the neck, medications to reduce inflammation or pain, physical therapy to improve mobility, and occupational therapy to assist with daily activities. In some cases, surgery may be necessary to relieve pressure on the spinal cord or repair structural damage.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and the timeliness of treatment. Recovery may be partial or complete, with some individuals regaining function over time. Follow-up care is essential to monitor for complications, adjust treatment plans, and support rehabilitation. Long-term management may involve ongoing therapy and assistive devices.

Complications

• Persistent motor or sensory deficits.
• Autonomic dysfunction, such as bladder or bowel problems.
• Increased risk of infections, such as pneumonia or urinary tract infections.
• Chronic pain or spasticity.

Lifestyle & Prevention

• Avoid high-risk activities that may lead to neck injury.
• Use proper techniques for lifting or repetitive neck movements.
• Maintain good posture and spinal health through exercise and ergonomic practices.
• Seek prompt medical attention for neck injuries to prevent further damage.

When to Seek Professional Help

• Sudden or severe neck pain following trauma.
• New or worsening neurological symptoms, such as weakness, numbness, or loss of sensation.
• Difficulty with balance, coordination, or bladder/bowel control.
• Signs of infection, such as fever or increased pain.

Tips for Medical Coders

This code (S14.144D) is used for a subsequent encounter for Brown-Sequard syndrome at the C4 level of the cervical spinal cord. Documentation should specify the level of the injury (C4) and confirm the encounter is subsequent (not initial or acute). Ensure the record includes details of the injury, treatment provided, and any ongoing management to support accurate coding.
