S82.62 Displaced fracture of lateral malleolus of left fibula

Name of the Condition

• Displaced fracture of lateral malleolus of left fibula

Summary

A displaced fracture of the lateral malleolus of the left fibula is a break in the outer ankle bone (fibula) where the bone fragment shifts from its normal anatomical position. This injury typically results from trauma and may involve instability of the ankle joint.

Causes

Direct trauma to the ankle, such as a fall or impact. Sudden twisting or rolling of the ankle. High-impact injuries, including sports-related accidents or motor vehicle collisions.

Risk Factors

• Participation in activities with a high risk of ankle injury (e.g., contact sports, skiing).
• Osteoporosis or other conditions that weaken bone density.
• Previous ankle injuries that may compromise structural integrity.
• Age-related changes in bone strength.

Symptoms

• Severe pain localized to the outer ankle.
• Swelling and bruising around the fracture site.
• Inability to bear weight or walk without assistance.
• Visible deformity or abnormal positioning of the ankle.

Diagnosis

Diagnosis begins with a physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are used to confirm the fracture and evaluate displacement. Advanced imaging (e.g., CT or MRI) may be employed for detailed assessment, particularly if surgical intervention is considered.

Treatment Options

• Immobilization with a cast or splint to stabilize the fracture.
• Pain management through medications or ice therapy.
• Surgical intervention for displaced or unstable fractures, often involving hardware like pins, screws, or plates.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Most fractures heal within 6–8 weeks with proper immobilization. Follow-up appointments monitor healing progress and may include repeat imaging. Return to normal activities depends on fracture severity and treatment. Long-term outcomes are generally favorable with appropriate care.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in an abnormal position.
• Chronic pain or arthritis in the ankle joint.
• Nerve or blood vessel damage in severe cases.

Lifestyle & Prevention

• Wear supportive footwear and use ankle braces during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid uneven surfaces or hazardous environments that increase fall risk.
• Strengthen ankle muscles through targeted exercises to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe ankle pain, swelling, or deformity after an injury. Persistent pain, inability to bear weight, or signs of infection (e.g., redness, fever) also warrant prompt evaluation.

Tips for Medical Coders

Document the specific side (left fibula) and displacement status to ensure accurate coding. Include details on fracture type (e.g., open/closed) and encounter stage (e.g., initial, subsequent) as required for complete code assignment. Verify clinical documentation supports the use of S82.62.
