M00.212 Other streptococcal arthritis, left shoulder

Name of the Condition

• Other streptococcal arthritis, left shoulder

Summary

Other streptococcal arthritis, left shoulder, is a bacterial infection of the left 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, left shoulder, is caused by infection with streptococcal bacteria (excluding Streptococcus pneumoniae) in the left 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 left shoulder joint pain, swelling, and warmth.
• Fever and chills.
• Reduced range of motion in the left shoulder.
• Fatigue and malaise.
• Redness over the left 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 arthritis. Follow-up includes monitoring for recurrence, assessing joint function, and adjusting treatment as needed.

Complications

• Joint destruction or deformity.
• Chronic arthritis.
• Sepsis or systemic infection.
• Spread of infection to other areas.

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, or signs of infection (e.g., redness, swelling) to prevent complications.

Tips for Medical Coders

Document the specific joint (left shoulder) and confirm streptococcal infection (excluding Streptococcus pneumoniae) to support accurate coding. Include clinical details like joint aspiration results or imaging findings to validate the diagnosis.
