M65.04 Abscess of tendon sheath, hand

Name of the Condition

• Abscess of tendon sheath, hand

Summary

Abscess of the tendon sheath in the hand is a localized infection characterized by pus accumulation within the protective sheath surrounding the tendons of the hand. This condition can cause pain, swelling, and impaired hand movement if not treated promptly.

Causes

Bacterial infections are the primary cause, often resulting from trauma, puncture wounds, or the spread of infection from other body areas. Less commonly, it may arise from systemic infections.

Risk Factors

• Recent injuries or penetrative wounds to the hand
• Pre-existing conditions like diabetes or immune deficiencies
• Poor wound hygiene, especially after minor injuries
• Occupational or recreational activities involving repetitive hand use

Symptoms

• Swelling and redness around the tendon sheath
• Pain or tenderness, particularly with hand movement
• Warmth in the affected area
• Possible fever or chills indicating systemic infection
• Limited range of motion in the hand

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and movement limitations. Blood tests may identify infectious agents, and imaging studies like MRI or ultrasound can confirm abscess presence.

Treatment Options

• Antibiotic therapy to address bacterial infection
• Surgical intervention may be necessary to drain the abscess

Prognosis and Follow-Up

With timely treatment, most cases resolve without long-term issues. Follow-up care ensures infection resolution and restores hand function.

Complications

• Spread of infection to surrounding tissues or bones
• Chronic pain or stiffness in the hand
• Tendon damage or rupture
• Systemic infection (sepsis) in severe cases

Lifestyle & Prevention

• Clean and properly care for hand wounds to prevent infection
• Avoid repetitive hand injuries or overuse
• Maintain good hygiene, especially after injuries
• Seek prompt medical attention for hand infections

When to Seek Professional Help

Consult a healthcare provider if you experience persistent hand pain, swelling, redness, or fever, as these may indicate an abscess or spreading infection.

Tips for Medical Coders

Document the specific location (hand) and confirm the presence of an abscess within the tendon sheath. Ensure clinical notes support the diagnosis to justify code assignment.
