S14.113 Complete lesion at C3 level of cervical spinal cord

Name of the Condition

• Complete lesion at C3 level of cervical spinal cord

Summary

This condition involves a complete disruption of the cervical spinal cord at the C3 level, resulting in the loss of all motor and sensory function below the injury site. The C3 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 C3 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 on the spinal cord, 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

• Respiratory issues due to impaired diaphragm function. Pressure sores from immobility. Urinary tract infections or bladder dysfunction. Blood clots (deep vein thrombosis). Chronic pain or spasticity.

Lifestyle & Prevention

• Avoid high-risk activities that may lead to neck injury. Use proper safety equipment during sports or work. Maintain good posture and ergonomic practices. Engage in regular exercise to strengthen neck and back muscles, as advised by a healthcare provider.

When to Seek Professional Help

Seek immediate medical attention if there is a suspected neck injury, especially after trauma. Symptoms such as loss of sensation, weakness, or difficulty breathing require urgent evaluation. Follow up with a healthcare provider for ongoing management of spinal cord injuries.

Tips for Medical Coders

Document the specific level of the cervical spinal cord (C3) and confirm the lesion is complete. Ensure clinical documentation supports the diagnosis, including details of the injury and any associated symptoms or complications. Code S14.113 is used for the initial encounter; subsequent encounters may require different codes based on the patient's status.
