M65.132 Other infective (teno)synovitis, left wrist

Name of the Condition

• Other infective (teno)synovitis, left wrist
• ICD-10 Code: M65.132

Summary

This condition involves an infection of the synovial sheath surrounding tendons (tenosynovitis) or the synovial membrane of the left wrist joint. It typically causes localized inflammation, pain, and functional impairment in the left 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 left wrist injuries (e.g., lacerations, fractures)
• Immunocompromised states (e.g., diabetes, HIV)
• Poor wound hygiene or delayed treatment of minor injuries
• Occupational or recreational exposure to pathogens (e.g., animal bites, contaminated environments)
• Prior left wrist surgery or invasive procedures

Symptoms

• Localized swelling, warmth, and tenderness over the affected tendon or joint in the left wrist
• Pain with movement or pressure
• Reduced range of motion or stiffness in the left 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 left 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 and pain management support recovery.

Prognosis and Follow-Up

With prompt treatment, most cases resolve without long-term complications. Follow-up ensures infection clearance and monitors for recurrence. Delayed care may lead to chronic pain or joint damage.

Complications

• Chronic wrist pain or stiffness
• Joint damage or reduced function
• Spread of infection to surrounding tissues or bloodstream
• Need for surgical intervention if untreated

Lifestyle & Prevention

• Clean and care for wrist injuries promptly to prevent infection.
• Maintain good hygiene, especially after exposure to pathogens.
• Manage underlying conditions (e.g., diabetes) to reduce infection risk.
• Avoid repetitive or high-risk activities that may injure the left wrist.

When to Seek Professional Help

Seek care if you experience persistent wrist pain, swelling, fever, or signs of infection (e.g., pus, redness). Early evaluation prevents complications.

Tips for Medical Coders

Document the specific site (left wrist) and confirm infective etiology. Ensure clinical notes support the diagnosis to justify code assignment.
