S14.112A Complete lesion at C2 level of cervical spinal cord, initial encounter

Name of the Condition

• Complete lesion at C2 level of cervical spinal cord, initial encounter

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. The term "initial encounter" indicates this is the patient's first presentation for this specific injury.

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 confirm the location and extent of the spinal cord injury. Additional tests may be performed to rule out other causes or assess associated injuries.

Treatment Options

Treatment focuses on stabilizing the injury, preventing further damage, and managing complications. 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, inflammation, or other symptoms.

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. Follow-up care typically involves ongoing rehabilitation, monitoring for complications, and adjustments to treatment plans as needed. Long-term management may include assistive devices or adaptive strategies to support daily activities.

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

• Using proper safety equipment during high-risk activities (e.g., helmets, seatbelts). Avoiding activities that strain the neck. Maintaining bone health through diet and exercise. Seeking prompt medical attention for neck injuries or symptoms of spinal cord damage.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden loss of movement or sensation in the limbs, severe neck pain, or difficulty breathing after a neck injury. Early intervention can help minimize damage and improve outcomes.

Tips for Medical Coders

Document the specific level of the cervical spinal cord (C2) and confirm the lesion is complete (no preserved sensory or motor function below the injury). Note the "initial encounter" to indicate this is the first presentation for the injury. Ensure documentation supports the traumatic or non-traumatic nature of the injury and any associated complications.
