M65.14 Other infective (teno)synovitis, hand

Name of the Condition

• Other infective (teno)synovitis, hand
• ICD-10 Code: M65.14

Summary

This condition involves an infection of the synovial sheath surrounding tendons in the hand, leading to inflammation, pain, and impaired movement. It is a localized form of infective tenosynovitis affecting the hand specifically.

Causes

The condition is typically caused by bacterial infections entering the synovial sheath. It may result from direct inoculation, such as puncture wounds or trauma, or from the spread of infection from nearby tissues. Less commonly, viral or fungal pathogens may be involved.

Risk Factors

• Recent hand injuries or puncture wounds
• Immunocompromised states (e.g., diabetes, HIV)
• Poor wound hygiene or delayed treatment of minor injuries
• Occupations requiring repetitive hand use or exposure to pathogens
• Prior hand surgery or invasive procedures

Symptoms

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

Diagnosis

Diagnosis involves a physical examination 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. Blood tests may also be used to evaluate systemic infection.

Treatment Options

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

Prognosis and Follow-Up

With prompt treatment, most patients recover fully. Follow-up may include monitoring for recurrence or complications. Delayed treatment can lead to chronic pain or functional impairment. Regular assessments ensure resolution of infection and restoration of mobility.

Complications

• Chronic tenosynovitis or persistent pain
• Tendon damage or rupture
• Spread of infection to surrounding tissues or bloodstream
• Long-term reduced hand function or stiffness

Lifestyle & Prevention

• Clean and properly care for hand injuries to prevent infection
• Avoid repetitive or strenuous hand movements if at risk
• Maintain good hygiene, especially in high-exposure environments
• Seek timely treatment for minor wounds to reduce infection risk

When to Seek Professional Help

Consult a healthcare provider if you experience persistent hand swelling, pain, warmth, or reduced mobility, especially after an injury. Seek immediate care for fever, pus, or signs of spreading infection.

Tips for Medical Coders

Document the specific hand involvement (e.g., left/right, digits) and any associated trauma or infection source. Ensure clinical notes support the diagnosis and specify whether the infection is bacterial, viral, or fungal if known. Use this code for localized hand infective tenosynovitis; do not use for unspecified sites or other anatomical locations.
