M46.26 Osteomyelitis of vertebra, lumbar region

Name of the Condition

• Osteomyelitis of vertebra, lumbar region

Summary

Osteomyelitis of vertebra, lumbar region is an infection of the lumbar vertebrae (lower 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 (localized to the lower spine)
• Fever
• Chills
• Weight loss
• Fatigue
• Neurological symptoms (if the infection affects the spinal cord)

Diagnosis

Diagnosing osteomyelitis of vertebra, lumbar region 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, timely treatment, and the patient’s overall health. Follow-up care often includes monitoring for recurrence and assessing spinal stability.

Complications

• Spinal cord compression
• Chronic pain
• Abscess formation
• Spread of infection to adjacent tissues
• Long-term neurological deficits

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk
• Manage chronic conditions (e.g., diabetes) effectively
• Avoid intravenous drug use
• Seek prompt treatment for infections, especially those near the spine

When to Seek Professional Help

Consult a healthcare provider if you experience persistent lower back pain, fever, or neurological symptoms (e.g., weakness, numbness) to rule out serious spinal infection.

Tips for Medical Coders

Document the specific lumbar region affected (e.g., L1-L5) and any associated complications. Ensure clinical notes support the diagnosis and treatment provided, as coding requires clear documentation of the infection’s location and severity.
