M00.059 Staphylococcal arthritis, unspecified hip

Name of the Condition

• Staphylococcal arthritis, unspecified hip

Summary

Staphylococcal arthritis, unspecified 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, unspecified 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, followed by oral therapy. Joint drainage may be necessary to remove pus and reduce pressure. Pain management and physical therapy support recovery.

Prognosis and Follow-Up

With prompt treatment, most patients recover without long-term joint damage. Follow-up includes monitoring for recurrence, assessing joint function, and adjusting antibiotics if needed. Delayed treatment increases the risk of permanent joint damage or sepsis.

Complications

• Joint destruction or osteomyelitis.
• Sepsis or systemic infection.
• Chronic arthritis or limited mobility.
• Need for surgical intervention (e.g., joint replacement).

Lifestyle & Prevention

• Practice good hygiene to reduce infection risk.
• Manage chronic conditions (e.g., diabetes) to support immune function.
• Seek prompt care for skin infections or injuries near the hip.
• Avoid intravenous drug use to lower infection exposure.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, fever, swelling, or reduced mobility, as these may indicate a serious infection requiring urgent care.

Tips for Medical Coders

Document the hip joint involvement as unspecified when the laterality (left/right) is not clearly stated. Ensure clinical notes support the diagnosis, as this code is used when the affected hip is not specified. Verify that infection is confirmed via lab or imaging results to justify the code.
