M65.042 Abscess of tendon sheath, left hand

Name of the Condition

• Abscess of tendon sheath, left hand

Summary

Abscess of the tendon sheath in the left hand is a localized infection characterized by pus accumulation within the protective sheath surrounding the tendons of the left 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 left 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 of the left hand
• 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 left 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
• Immobilization of the left hand to reduce movement and pain

Prognosis and Follow-Up

With timely treatment, most cases resolve without long-term issues. Follow-up care ensures infection resolution and monitors for recurrence. Physical therapy may be recommended to restore full hand function.

Complications

• Spread of infection to surrounding tissues or bloodstream
• Tendon damage or rupture
• Chronic pain or stiffness in the left hand
• Reduced hand mobility or function

Lifestyle & Prevention

• Clean and properly care for any hand injuries to prevent infection
• Avoid repetitive or strenuous hand activities that may cause trauma
• Maintain good overall health to support immune function
• Seek prompt medical attention for signs of infection

When to Seek Professional Help

Consult a healthcare provider if you experience persistent pain, swelling, redness, or fever in the left hand, especially after an injury. Early intervention can prevent complications.

Tips for Medical Coders

Document the specific location (left hand) and confirm the diagnosis of an abscess of the tendon sheath. Ensure clinical documentation supports the site and nature of the infection to justify code assignment.
