M00.05 Staphylococcal arthritis, hip

Name of the Condition

• Staphylococcal arthritis, hip

Summary

Staphylococcal arthritis, hip, is a bacterial infection affecting the hip joint, caused by Staphylococcus bacteria. It leads to rapid joint inflammation, pain, and potential damage if not treated promptly. This condition requires immediate medical attention to prevent complications.

Causes

Staphylococcal arthritis, hip, is primarily caused by infection with Staphylococcus bacteria, most commonly Staphylococcus aureus. The bacteria can enter the joint space through direct inoculation (e.g., injury or surgery), spread from nearby infections, or via the bloodstream from a distant site.

Risk Factors

• Recent hip surgery or invasive procedures.
• Immunocompromised states (e.g., diabetes, HIV, chemotherapy).
• Intravenous drug use.
• Pre-existing hip conditions (e.g., osteoarthritis, hip replacement).
• Skin infections or bacteremia.

Symptoms

• Severe hip pain, swelling, and warmth.
• Fever and chills.
• Reduced range of motion in the affected hip.
• Fatigue and malaise.
• Redness over the hip joint.

Diagnosis

Diagnosis involves joint aspiration to analyze synovial fluid for bacteria, blood cultures to identify systemic infection, and imaging (e.g., X-rays, MRI) to assess joint damage. Clinical evaluation and patient history are also critical.

Treatment Options

Treatment typically includes antibiotics to target the infection, often administered intravenously initially. Surgical intervention may be necessary to drain the joint or remove infected tissue. Pain management and physical therapy are also part of the care plan.

Prognosis and Follow-Up

With prompt treatment, most patients recover fully. Follow-up care includes monitoring for recurrence, assessing joint function, and adjusting treatment as needed. Delayed treatment can lead to permanent joint damage or sepsis.

Complications

• Joint destruction or deformity.
• Sepsis (systemic infection).
• Osteomyelitis (bone infection).
• Chronic arthritis or limited mobility.

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk.
• Promptly treat skin infections or wounds.
• Manage chronic conditions (e.g., diabetes) to support immune function.
• Avoid intravenous drug use.

When to Seek Professional Help

Seek immediate medical care if you experience severe hip pain, fever, or swelling, especially if you have a recent injury, surgery, or infection.

Tips for Medical Coders

Document the specific joint (hip) and confirm the bacterial cause (Staphylococcus) to support accurate coding. Include details on infection source, treatment, and complications if applicable. Ensure clinical documentation aligns with the diagnosis for proper code assignment.
