M00.211 Other streptococcal arthritis, right shoulder

Name of the Condition

• Other streptococcal arthritis, right shoulder

Summary

Other streptococcal arthritis, right shoulder, is a bacterial infection of the right shoulder joint caused by streptococcal bacteria other than Streptococcus pneumoniae. It results in joint inflammation and can lead to rapid joint damage if not treated promptly. This condition requires immediate medical attention to prevent complications.

Causes

Other streptococcal arthritis, right shoulder, is caused by infection with streptococcal bacteria (excluding Streptococcus pneumoniae) in the right shoulder joint space. The infection can spread through the bloodstream from a distant site, such as the skin or respiratory tract, or via direct inoculation into the joint.

Risk Factors

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

Symptoms

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

Treatment Options

• Antibiotics: Intravenous or oral antibiotics to target the infection.
• Joint Drainage: Needle aspiration, arthroscopy, or surgery to remove infected fluid.
• Immobilization: Splinting or bracing to reduce joint stress during recovery.

Prognosis and Follow-Up

With prompt treatment, prognosis is generally good, but delayed care can lead to joint damage or chronic issues. Follow-up includes monitoring for recurrence, assessing joint function, and adjusting treatment as needed.

Complications

• Joint destruction or deformity.
• Sepsis or systemic infection.
• Chronic arthritis.
• Spread of infection to nearby tissues.

Lifestyle & Prevention

• Maintain good hygiene to reduce infection risk.
• Manage underlying conditions (e.g., diabetes) to support immune function.
• Avoid intravenous drug use.
• Seek prompt treatment for skin or respiratory infections.

When to Seek Professional Help

Seek immediate medical care if experiencing severe shoulder pain, fever, swelling, or reduced mobility, as these may indicate a serious infection requiring urgent intervention.

Tips for Medical Coders

Document the specific joint (right shoulder) and confirm the causative organism is streptococcal (excluding Streptococcus pneumoniae). Ensure clinical notes support the diagnosis and specify the affected side for accurate coding.
