G00.3 Staphylococcal meningitis

Name of the Condition

• Staphylococcal meningitis

Summary

Staphylococcal meningitis is a bacterial infection of the meninges, the protective membranes surrounding the brain and spinal cord, caused by Staphylococcus bacteria. This condition requires prompt medical attention due to its potential for rapid progression and severe complications.

Causes

Staphylococcal meningitis is caused by Staphylococcus bacteria, which typically enter the bloodstream and cross the blood-brain barrier, leading to infection of the meninges. The bacteria can spread through direct contact with infected wounds, surgical sites, or contaminated medical devices.

Risk Factors

• Recent surgery or invasive procedures.
• Presence of indwelling medical devices (e.g., catheters, shunts).
• Skin infections or abscesses caused by Staphylococcus.
• Weakened immune system.
• Hospitalization, particularly in intensive care settings.
• Prior antibiotic use, which may promote resistant strains.

Symptoms

• Sudden high fever.
• Severe headache.
• Stiff neck.
• Nausea and vomiting.
• Sensitivity to light (photophobia).
• Altered mental status or confusion.
• In infants, symptoms may include irritability, poor feeding, and bulging fontanelle.

Diagnosis

Diagnosis involves a lumbar puncture to analyze cerebrospinal fluid for bacterial presence, white blood cell count, and glucose levels. Blood cultures, imaging (CT or MRI), and rapid bacterial antigen tests may also be used to confirm the causative organism.

Treatment Options

Treatment typically includes high-dose intravenous antibiotics targeted against Staphylococcus (e.g., vancomycin, nafcillin) and supportive care. In some cases, surgical drainage of infected sites or removal of contaminated devices may be necessary.

Prognosis and Follow-Up

Prognosis depends on the timeliness of treatment, the patient’s overall health, and the presence of complications. Recovery may require extended hospitalization and follow-up to monitor for neurological sequelae. Long-term outcomes can range from full recovery to persistent deficits.

Complications

• Seizures.
• Brain damage or cognitive impairment.
• Hearing loss.
• Hydrocephalus.
• Septic shock.
• Death, particularly in severe or untreated cases.

Lifestyle & Prevention

• Maintain good hygiene, especially after surgery or wound care.
• Ensure proper care of indwelling medical devices to prevent infection.
• Seek prompt treatment for skin infections or abscesses.
• Follow healthcare provider recommendations for infection control in hospital settings.

When to Seek Professional Help

Seek immediate medical attention if symptoms such as sudden high fever, severe headache, stiff neck, or altered mental status occur, as these may indicate meningitis. Early intervention is critical to improve outcomes.

Tips for Medical Coders

When coding for staphylococcal meningitis, ensure documentation supports the bacterial cause (e.g., culture results, clinical findings). Verify that the code G00.3 is used for meningitis specifically caused by Staphylococcus and not other bacterial pathogens. Document any associated conditions (e.g., sepsis, device-related infections) separately if applicable.
