S14.112 Complete lesion at C2 level of cervical spinal cord

Name of the Condition

• Complete lesion at C2 level of cervical spinal cord

Summary

This condition involves a complete disruption of the cervical spinal cord at the C2 level, resulting in the loss of all motor and sensory function below the injury site. The C2 level is part of the cervical spinal cord, which transmits signals between the brain and the upper body. A complete lesion typically leads to paralysis and loss of sensation in the arms, trunk, and legs, depending on the specific segment affected.

Causes

Complete lesions at the C2 level of the cervical spinal cord are most commonly caused by traumatic events, such as motor vehicle accidents, falls, or direct blows to the neck. Penetrating injuries, sports-related trauma, or compression from fractures or dislocations may also result in complete damage. Non-traumatic causes, including tumors, infections, or severe degenerative conditions, can occasionally lead to a complete lesion.

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 integrity (e.g., osteoporosis). Previous neck injuries or congenital spinal abnormalities.

Symptoms

• Loss of motor function (paralysis) in the arms, trunk, and legs below the injury level. Absence of sensation (touch, pain, temperature) below the level of the lesion. Impaired autonomic functions, such as changes in blood pressure or bladder control.

Diagnosis

Diagnosis is based on clinical evaluation, including a thorough neurological examination to assess motor and sensory function. Imaging studies, such as MRI or CT scans, are typically used to visualize the spinal cord and identify the extent of the lesion. Additional tests may be performed to rule out other conditions or assess complications.

Treatment Options

Treatment focuses on stabilizing the injury, preventing further damage, and managing symptoms. This may include immobilization of the neck, surgical intervention to relieve pressure or stabilize the spine, and rehabilitation to improve function. Medications may be used to manage pain, spasticity, or other complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the injury and the level of function preserved. Complete lesions often result in permanent loss of function below the injury site. Long-term follow-up is essential to monitor for complications, adjust treatment plans, and provide support for rehabilitation and adaptive strategies.

Complications

Potential complications include respiratory issues due to impaired diaphragm function, pressure sores from immobility, urinary tract infections, blood clots, and chronic pain. Autonomic dysreflexia, a dangerous rise in blood pressure, may also occur.

Lifestyle & Prevention

Preventive measures include using proper safety equipment during high-risk activities, maintaining good posture, and avoiding behaviors that increase neck injury risk. For individuals with existing conditions, regular medical check-ups and adherence to treatment plans can help reduce complications.

When to Seek Professional Help

Seek immediate medical attention if there are signs of neck injury, such as severe pain, loss of sensation, or inability to move limbs. Prompt evaluation is critical to minimize damage and improve outcomes.

Tips for Medical Coders

Document the specific level of the cervical spinal cord lesion (C2) and confirm the completeness of the lesion. Ensure clinical documentation supports the diagnosis and any associated complications or sequela. Code S14.112 is used for the acute phase of the injury; follow-up care or chronic effects may require additional coding.
