M46.38 Infection of intervertebral disc (pyogenic), sacral and sacrococcygeal region

Name of the Condition

• Infection of Intervertebral Disc (Pyogenic), Sacral and Sacrococcygeal Region

Summary

Infection of the intervertebral disc (pyogenic) in the sacral and sacrococcygeal region is a bacterial infection affecting the intervertebral disc and adjacent structures in the lower spine. This condition involves inflammation and infection of the disc space, potentially leading to pain, structural damage, and systemic symptoms. It is a serious spinal infection that requires prompt medical attention.

Causes

Pyogenic disc infection in this region is typically caused by bacterial pathogens, such as Staphylococcus aureus or Streptococcus species. The infection may enter the disc space through hematogenous spread (via the bloodstream) or direct inoculation, often following trauma, surgery, or invasive procedures. The inflammatory response can result in disc destruction and spread to adjacent tissues.

Risk Factors

• Recent spinal surgery or invasive procedures in the sacral/sacrococcygeal region.
• Immunocompromised states (e.g., diabetes, HIV, or chronic steroid use).
• Intravenous drug use.
• Pre-existing spinal conditions or trauma affecting the sacral/sacrococcygeal area.
• Advanced age.

Symptoms

• Severe, localized lower back or sacral pain that worsens with movement.
• Fever, chills, or other systemic signs of infection.
• Reduced spinal mobility or stiffness in the lower back.
• Possible radiating pain to the legs if nerve roots are involved.
• In some cases, visible swelling or tenderness over the affected area.

Diagnosis

Diagnosis is based on clinical evaluation, imaging (e.g., MRI or CT), and laboratory testing. Imaging helps identify disc space infection and adjacent tissue involvement, while blood tests or disc aspiration may confirm bacterial presence. Clinical correlation with symptoms and risk factors is essential.

Treatment Options

Treatment typically involves antibiotic therapy targeted at the identified pathogen, often administered intravenously initially. Surgical intervention may be necessary to drain abscesses or stabilize the spine if structural damage occurs. Pain management and physical therapy may support recovery.

Prognosis and Follow-Up

Prognosis depends on early diagnosis and treatment. With prompt intervention, many patients recover without long-term complications. Follow-up imaging and clinical assessments monitor healing and detect recurrence. Chronic cases may require extended antibiotic courses or ongoing spinal monitoring.

Complications

• Spinal instability or deformity.
• Abscess formation or spread to surrounding tissues.
• Neurological deficits (e.g., weakness, numbness) from nerve root compression.
• Chronic pain or recurrent infection.
• Sepsis in severe cases.

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk.
• Avoid unnecessary spinal procedures or trauma.
• Manage chronic conditions (e.g., diabetes) to support immune function.
• Seek prompt care for spinal injuries or infections.

When to Seek Professional Help

Seek immediate medical attention if you experience severe lower back pain with fever, sudden neurological symptoms (e.g., leg weakness), or signs of systemic infection (e.g., chills, confusion).

Tips for Medical Coders

Document the specific anatomical location (sacral and sacrococcygeal region) and confirm pyogenic (bacterial) infection to support accurate coding. Include details on diagnostic methods (e.g., imaging, lab results) and treatment approaches for comprehensive coding. Ensure documentation aligns with clinical findings to reflect the condition accurately.
