M65.05 Abscess of tendon sheath, thigh

Name of the Condition

• Abscess of tendon sheath, thigh

Summary

Abscess of the tendon sheath in the thigh is a localized infection characterized by pus accumulation within the protective sheath surrounding a tendon in the thigh. This condition can cause pain, swelling, and impaired 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 thigh
• Pre-existing conditions like diabetes or immune deficiencies
• Poor wound hygiene, especially after minor injuries

Symptoms

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

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 monitors for recurrence.

Complications

• Spread of infection to surrounding tissues
• Chronic pain or limited mobility
• Systemic infection if left untreated

Lifestyle & Prevention

• Maintain good wound hygiene after injuries
• Seek prompt care for deep or penetrating wounds
• Manage underlying conditions like diabetes to reduce infection risk

When to Seek Professional Help

Consult a healthcare provider if you experience persistent thigh pain, swelling, redness, or fever, as these may indicate an abscess requiring medical attention.

Tips for Medical Coders

Document the specific location (thigh) and confirm the diagnosis of an abscess within the tendon sheath. Ensure clinical notes support the infection and its anatomical site for accurate coding.
