S82.40 Unspecified fracture of shaft of fibula

Name of the Condition

• Unspecified fracture of shaft of fibula
• ICD-10 Code: S82.40

Summary

This condition refers to a fracture (break) of the middle portion of the fibula, the smaller of the two bones in the lower leg. The term "unspecified" indicates that the exact location of the fracture on the fibula has not been pinpointed. This is a closed fracture, meaning the bone is broken but the skin is not pierced.

Causes

Most commonly caused by direct trauma or impact to the outside of the leg, such as from falls, sports injuries, or accidents.

Risk Factors

• Participation in contact sports.
• High-risk occupations or activities that increase the likelihood of falls or impacts.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.

Symptoms

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

Diagnosis

Physical examination by a healthcare professional. Imaging tests such as X-rays, to determine the exact location and extent of the fracture.

Treatment Options

• Immobilization of the leg using a splint or cast to allow the bone to heal properly.
• Pain management with medications such as analgesics.
• Physical therapy to restore movement and strength post-recovery.
• Surgery may be required for severe or displaced fractures.

Prognosis and Follow-Up

Most fractures of the fibular shaft heal well with appropriate treatment. Recovery time varies but typically ranges from 6 to 8 weeks. Follow-up appointments are necessary to monitor healing and adjust treatment as needed.

Complications

• Delayed healing or nonunion of the fracture.
• Malunion, where the bone heals in an incorrect position.
• Nerve or blood vessel damage near the fracture site.
• Chronic pain or instability in the leg.

Lifestyle & Prevention

• Wear protective gear during high-risk activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid activities that increase fall risk, especially in older adults.
• Strengthen leg muscles to improve stability and reduce injury likelihood.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness, pus) at the injury site.

Tips for Medical Coders

Document the fracture as unspecified when the exact location on the fibula shaft is not clearly identified. Ensure the encounter type (e.g., initial, subsequent) and fracture status (open/closed) are accurately recorded to support coding specificity.
