M46.2 Osteomyelitis of vertebra

Name of the Condition

• Osteomyelitis of vertebra

Summary

Osteomyelitis of vertebra is an infection of the vertebral bones in the spine, typically caused by bacteria or fungi. The infection leads to inflammation and can damage spinal structures, potentially affecting surrounding tissues or the spinal cord.

Causes

The condition is most commonly caused by bacterial infections, often Staphylococcus aureus. It may also result from fungal infections or spread from a nearby infection or through the bloodstream from another part of the body.

Risk Factors

• Advanced age
• Diabetes
• Immune suppression (e.g., HIV/AIDS, cancer)
• Intravenous drug use
• Recent surgery or invasive procedures
• Existing infections

Symptoms

• Back pain
• Fever
• Chills
• Weight loss
• Fatigue
• Neurological symptoms (if the infection affects the spinal cord)

Diagnosis

Diagnosing osteomyelitis of vertebra may involve blood tests to identify infection markers, imaging studies like MRI or CT scans for detailed views of the spine, and possibly a biopsy to identify the causative microorganism.

Treatment Options

Treatment typically includes antibiotics or antifungal medications to eradicate the infection. In severe cases, surgical intervention may be necessary to remove infected tissue or stabilize the spine.

Prognosis and Follow-Up

Prognosis depends on the severity of the infection, the patient’s overall health, and timely treatment. Follow-up care often includes monitoring for recurrence and assessing spinal stability.

Complications

• Spinal cord compression
• Abscess formation
• Chronic infection
• Spinal deformity or instability

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk
• Manage chronic conditions like diabetes
• Avoid intravenous drug use
• Seek prompt treatment for infections

When to Seek Professional Help

Seek medical attention if you experience persistent back pain, fever, or neurological symptoms, as these may indicate a serious spinal infection.

Tips for Medical Coders

When coding for osteomyelitis of vertebra (M46.2), ensure documentation specifies the infection’s location and any associated complications. Verify that the diagnosis aligns with clinical findings and imaging results to support accurate code assignment.
