Name of the Condition

• Other infective (teno)synovitis, unspecified hand
• ICD-10 Code: M65.149

Summary

• This form of synovitis involves an infection in the synovial sheath surrounding tendons, specifically affecting the hand. It results in swelling, pain, and reduced mobility.

Causes

• The condition is often caused by bacterial infections. It can occur following an injury to the hand, such as a puncture wound, or from the spread of an infection elsewhere in the body.

Risk Factors

• Factors increasing risk include recent hand injuries, immunocompromised states (e.g., diabetes, HIV/AIDS), poor wound care, and occupations requiring repetitive hand movements.

Symptoms

• Patients usually experience swelling, tenderness, warmth in the affected hand, decreased range of motion, and sometimes a fever due to systemic infection.

Diagnosis

• Diagnosis can involve a physical examination, MRI or ultrasound to visualize inflammation, and laboratory tests such as blood cultures or aspiration of synovial fluid to identify infectious agents.

Treatment Options

• Antibiotics are typically prescribed to combat the infection. In some cases, surgical intervention may be necessary to drain pus or debride infected tissues. Rest and immobilization of the hand, along with physical therapy, can support recovery.

Prognosis and Follow-Up

• With prompt and appropriate treatment, many patients recover fully. However, follow-up is crucial to ensure the infection resolves completely and to monitor hand function recovery.

Complications

• If untreated, complications like chronic pain, impaired hand function, systemic spread of infection, or tendon rupture can occur.

Lifestyle & Prevention

• Preventive measures include prompt treatment of hand injuries, maintaining good hand hygiene, and managing underlying health conditions like diabetes.

When to Seek Professional Help

• Seek immediate medical attention if experiencing sudden hand swelling, redness, severe pain, fever, or if there's a suspected infection following a hand injury.

Additional Resources

• Visit reputable health sites like the Mayo Clinic or CDC for more detailed information, or join patient support groups for shared experiences and advice.

Tips for Medical Coders

• Ensure specificity by coding additional identifiers pertinent to the infection. Avoid coding errors by verifying clinical documentation aligns with the condition described.
