S82.426 Nondisplaced transverse fracture of shaft of unspecified fibula

Name of the Condition

• Nondisplaced transverse fracture of shaft of unspecified fibula
• ICD-10 Code: S82.426

Summary

A nondisplaced transverse fracture of the shaft of the unspecified fibula is a break in the long, thin bone on the lateral side of the lower leg, where the fracture line runs horizontally across the middle portion of the bone. The bone fragments remain in their normal anatomical alignment, meaning there is no significant separation or mispositioning of the broken parts.

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 or twisting motions can 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

• Immobilization of the leg with a cast or brace to allow healing.
• Pain management with medications or other therapies.
• Physical therapy to restore strength and mobility after healing.
• Surgical intervention is rarely required for nondisplaced fractures but may be considered in specific cases.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, as they often heal well with proper immobilization and care. Follow-up appointments are typically scheduled to monitor healing progress, assess for complications, and guide rehabilitation.

Complications

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

Lifestyle & Prevention

• Wear appropriate protective gear during sports or high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid activities that increase the risk of falls or leg injuries.
• Use caution on uneven surfaces or in environments with tripping hazards.

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

When coding for S82.426, ensure the documentation specifies a transverse fracture of the fibula shaft that is nondisplaced and does not indicate laterality (right or left). Verify that the fracture is not associated with displacement, as this would require a different code. Confirm the anatomical location (shaft of fibula) and fracture type (transverse) are clearly documented to support accurate coding.
