M65.131 Other infective (teno)synovitis, right wrist

Name of the Condition

• Other infective (teno)synovitis, right wrist
• ICD-10 Code: M65.131

Summary

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

• Recent wrist injuries (e.g., lacerations, fractures)
• Immunocompromised states (e.g., diabetes, HIV, chemotherapy)
• Poor wound hygiene or delayed treatment of minor injuries
• Occupational or recreational exposure to pathogens (e.g., animal bites, contaminated environments)
• Prior wrist surgery or invasive procedures

Symptoms

• Localized swelling, warmth, and tenderness over the right wrist
• Pain with movement or pressure
• Reduced range of motion or stiffness in the wrist
• Systemic signs (e.g., fever, chills) if infection is severe or widespread
• Possible drainage or pus if the infection is advanced

Diagnosis

Diagnosis involves a physical exam to assess inflammation and mobility in the right wrist. 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.
• Immobilization of the wrist to reduce pain and promote healing.
• Pain management with analgesics as needed.
• Physical therapy to restore function after resolution of infection.

Prognosis and Follow-Up

With prompt treatment, most cases resolve without long-term complications. Follow-up may include monitoring for recurrence, assessing functional recovery, and adjusting treatment based on culture results or clinical response.

Complications

• Chronic tenosynovitis or joint damage if untreated.
• Spread of infection to surrounding tissues or systemic sepsis.
• Tendon rupture or permanent mobility loss in severe cases.

Lifestyle & Prevention

• Maintain good wound hygiene, especially after injuries.
• Avoid exposure to contaminated environments or pathogens.
• Manage underlying conditions (e.g., diabetes) to reduce infection risk.
• Seek timely care for wrist injuries to prevent infection.

When to Seek Professional Help

Consult a healthcare provider if you experience persistent wrist pain, swelling, warmth, or signs of infection (e.g., fever, pus). Immediate care is needed for severe symptoms or systemic involvement.

Tips for Medical Coders

Document the specific anatomical site (right wrist) and confirm infective etiology. Ensure clinical notes support the diagnosis, including signs of infection (e.g., fever, pus) or diagnostic tests (e.g., cultures). Use M65.131 for right wrist involvement; do not use this code for non-infective or unspecified site cases.
