M65.111 Other infective (teno)synovitis, right shoulder

Name of the Condition

• Other infective (teno)synovitis, right shoulder
• ICD-10 Code: M65.111

Summary

This condition involves an infection of the synovial sheath surrounding tendons (tenosynovitis) or the synovial membrane of the right shoulder joint. It typically causes localized inflammation, pain, and functional impairment in the shoulder region.

Causes

The condition is most commonly caused by bacterial infections, though viral or fungal pathogens may also be involved. It can arise from direct inoculation (e.g., trauma, surgery) or hematogenous spread from a distant infection.

Risk Factors

• Factors increasing risk include recent shoulder injuries, immunocompromised states (e.g., diabetes, HIV), poor wound hygiene, and occupations with repetitive shoulder motion or exposure to pathogens.

Symptoms

• Patients may experience swelling, tenderness, warmth, and reduced mobility in the right shoulder. Systemic symptoms like fever or malaise may occur if the infection is severe.

Diagnosis

Diagnosis involves a physical exam to assess inflammation and mobility. Imaging (e.g., MRI, ultrasound) visualizes soft tissue changes, while laboratory tests (e.g., synovial fluid analysis, cultures) identify infectious agents.

Treatment Options

• Antibiotics are the primary treatment for bacterial infections. Surgical drainage or debridement may be necessary for abscesses or severe cases. Rest and immobilization of the shoulder, along with physical therapy, support recovery.

Prognosis and Follow-Up

With prompt treatment, most patients recover fully. Follow-up may include monitoring for resolution of symptoms and assessing shoulder function. Delayed treatment can lead to chronic pain or joint damage.

Complications

• Potential complications include chronic synovitis, joint destruction, sepsis, or spread of infection to surrounding tissues. Early intervention reduces these risks.

Lifestyle & Prevention

• Maintain good wound hygiene, especially after shoulder injuries or procedures. Avoid repetitive shoulder strain and seek prompt care for infections. Immunocompromised individuals should take extra precautions.

When to Seek Professional Help

• Seek care if shoulder pain, swelling, or warmth persists or worsens, or if systemic symptoms (e.g., fever) develop. Early evaluation prevents complications.

Tips for Medical Coders

• Use M65.111 for infective tenosynovitis or synovitis of the right shoulder. Document laterality (right) and confirm infection is the primary cause. Include clinical details (e.g., bacterial vs. other pathogens) if available for specificity.
