Name of the Condition

• Nondisplaced fracture of the lateral malleolus of the right fibula
• ICD-10 Code: S82.64XA

Summary

A nondisplaced fracture of the lateral malleolus of the right fibula is a type of ankle fracture where the bone remains aligned despite being broken. This injury typically results from twisting or an impact but does not involve the bone fragment moving out of place.

Causes

• Traumatic injuries such as falls, sports injuries, or car accidents.
• Sudden twisting or rolling of the ankle.

Risk Factors

• Participation in high-impact sports or activities.
• Poor coordination or balance.
• Osteoporosis or weakened bones due to aging.

Symptoms

• Swelling and tenderness around the ankle.
• Pain, especially when bearing weight.
• Bruising in the ankle area.
• Limited range of motion in the ankle.

Diagnosis

• Physical examination of the ankle for swelling and tenderness.
• Imaging tests, such as X-rays, to confirm the fracture's presence and ascertain whether it is nondisplaced.

Treatment Options

• Rest, ice, compression, and elevation (RICE) to reduce swelling.
• Immobilization using a cast or splint to keep the bone in place.
• Over-the-counter pain relievers like ibuprofen or acetaminophen to manage pain.
• Physical therapy to restore strength and mobility once healing begins.

Prognosis and Follow-Up

• With proper care, most nondisplaced fractures heal without long-term issues.
• Regular follow-ups to ensure proper healing through physical examinations and repeat X-rays.
• Physical therapy may be required to regain full function.

Complications

• If left untreated, the fracture could displace or not heal correctly, leading to chronic pain or instability.
• Potential for developing arthritis in the ankle joint if the fracture affects joint surfaces.

Lifestyle & Prevention

• Strengthening exercises to improve balance and support around the ankle.
• Wearing appropriate and supportive footwear during physical activities.
• Maintaining bone health through calcium and vitamin D-rich diets.

When to Seek Professional Help

• Inability to bear weight on the ankle.
• Significant swelling, bruising, or deformity in the ankle area.
• Persistent pain despite home treatment efforts.

Tips for Medical Coders

• Ensure the specification of the fracture as nondisplaced and of the right fibula.
• Verify the initial encounter for a closed fracture to use the correct code, S82.64XA.
• Avoid confusion with similar codes for open fractures or different fracture locations on the fibula.
