S82.499A Other fracture of shaft of unspecified fibula, initial encounter for closed fracture

Name of the Condition

• Other fracture of shaft of unspecified fibula, initial encounter for closed fracture
• ICD-10 Code: S82.499A

Summary

This condition describes a fracture of the shaft (middle portion) of the fibula, the smaller bone in the lower leg, where the specific side (right or left) is not documented. The term "other" indicates a fracture type not classified under more detailed subcategories (e.g., transverse, oblique). The injury is closed (skin intact) and represents the initial encounter for treatment. Severity may vary, including displaced or non-displaced fractures.

Causes

Most commonly caused by direct trauma or impact to the leg, such as from falls, sports injuries, or motor vehicle accidents. High-force impacts, twisting motions, or repetitive stress may also lead to this type of fracture.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries.

Symptoms

• Pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine its extent and alignment.

Treatment Options

Treatment depends on fracture severity and may include immobilization with a cast or brace, pain management, and physical therapy. Severe or displaced fractures may require surgical intervention, such as internal fixation.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time varies based on fracture severity and patient health. Follow-up care often includes monitoring healing progress and gradual return to weight-bearing activities, guided by clinical evaluation.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), chronic pain, or nerve damage. Infection risk is low for closed fractures but may increase with open injuries.

Lifestyle & Prevention

• Wear protective gear during high-risk activities (e.g., sports).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive high-impact motions that strain the leg.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the encounter as initial for a closed fracture of the fibula shaft. Ensure the unspecified side is appropriate (e.g., when side is not documented or clinically irrelevant). Verify that "closed" is confirmed (no skin breach) and that the fracture is of the shaft (not proximal/distal).
