S82.423A Displaced transverse fracture of shaft of unspecified fibula, initial encounter for closed fracture

Name of the Condition

• Displaced transverse fracture of shaft of unspecified fibula, initial encounter for closed fracture
• ICD-10 Code: S82.423A

Summary

A displaced 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 bone fragments are separated and misaligned. The fracture line runs horizontally across the middle portion of the bone, and the displacement indicates the fragments are not in their normal anatomical position. This is an initial encounter for a closed fracture, meaning the skin is intact and the fracture has not pierced through the skin.

Causes

Most commonly caused by direct trauma or high-impact forces to the leg, such as falls, sports injuries, or motor vehicle accidents. Twisting motions or sudden impacts 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.
• Visible 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, determine its extent, and evaluate the degree of displacement. The "closed fracture" classification is confirmed by the absence of an open wound or skin penetration.

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 may be required if the fracture is severely displaced or unstable.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though recovery time depends on the severity of the fracture and individual healing factors. Follow-up care typically includes monitoring for proper healing and rehabilitation to restore function. Long-term outcomes are usually good, but some patients may experience residual stiffness or weakness.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in a misaligned position.
• Chronic pain or instability in the lower leg.
• Nerve or blood vessel damage in severe cases.

Lifestyle & Prevention

• Wear appropriate protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid activities that increase the risk of falls or direct leg trauma.
• Engage in regular weight-bearing exercise to strengthen bones.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of an open wound. Persistent pain, swelling, or difficulty walking after an injury should also prompt a healthcare evaluation.

Tips for Medical Coders

This code (S82.423A) is specific to a displaced transverse fracture of the fibula shaft, unspecified side, with an initial encounter for a closed fracture. Documentation should clearly indicate the fracture type (transverse), displacement, anatomical location (shaft of fibula), laterality (unspecified), encounter type (initial), and fracture status (closed). Ensure the record supports these elements to justify the code selection.
