M65.141 Other infective (teno)synovitis, right hand

Name of the Condition

• Other infective (teno)synovitis, right hand
• ICD-10 Code: M65.141

Summary

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

Causes

The condition is typically caused by bacterial, viral, or fungal pathogens entering the synovial sheath. Infections may arise from direct inoculation (e.g., puncture wounds, surgical procedures) or hematogenous spread from systemic infections. Trauma or pre-existing tendon/joint abnormalities can facilitate pathogen entry.

Risk Factors

• Recent right hand injuries (e.g., lacerations, fractures)
• Immunocompromised states (e.g., diabetes, HIV, chemotherapy)
• Poor wound hygiene or delayed treatment of minor injuries
• Occupations or activities with repetitive hand use or exposure to pathogens (e.g., animal bites, contaminated environments)
• Prior right hand surgery or invasive procedures

Symptoms

• Localized swelling, warmth, and tenderness over the affected tendon or joint in the right hand
• Pain with movement or pressure
• Reduced range of motion or stiffness in the right hand
• 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 hand. 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 involvement.

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 right hand, along with physical therapy, can support recovery.

Prognosis and Follow-Up

With prompt treatment, most cases resolve without long-term complications. Follow-up may include monitoring for recurrence or residual stiffness. Severe or delayed treatment can lead to chronic pain, tendon damage, or functional impairment in the right hand.

Complications

• Tendon rupture or damage
• Chronic pain or stiffness in the right hand
• Spread of infection to surrounding tissues or systemic circulation
• Functional impairment affecting daily activities

Lifestyle & Prevention

• Practice good hand hygiene, especially after injuries or exposure to contaminants.
• Promptly clean and treat minor wounds to the right hand.
• Avoid repetitive or strenuous hand movements if at risk.
• Maintain overall health to support immune function.

When to Seek Professional Help

Seek care if you experience persistent swelling, pain, or warmth in the right hand, especially with fever or reduced mobility. Early intervention improves outcomes and prevents complications.

Tips for Medical Coders

• Use M65.141 for infective tenosynovitis localized to the right hand.
• Document the anatomical site (right hand) and infectious nature to support code specificity.
• Include details on causative organisms or treatment if available, as these may impact coding accuracy.
