S82.425D Nondisplaced transverse fracture of shaft of left fibula, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced transverse fracture of shaft of left fibula, subsequent encounter for closed fracture with routine healing
• ICD-10 Code: S82.425D

Summary

A nondisplaced transverse fracture of the shaft of the left 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, and the fracture is classified as closed (no break in the skin). This code is used for a subsequent encounter when the fracture is healing routinely without complications.

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. For a subsequent encounter, documentation should show evidence of routine healing, such as callus formation or reduced fracture line visibility.

Treatment Options

• Immobilization with a cast or brace to support healing.
• Pain management with medications or physical therapy.
• Monitoring for signs of proper bone union during follow-up visits.

Prognosis and Follow-Up

With proper treatment, nondisplaced fractures of the fibula generally heal well. Follow-up care may include periodic imaging to confirm healing progress and gradual return to weight-bearing activities as tolerated. Routine healing is expected when the fracture site shows progressive stability and reduced symptoms.

Complications

• Delayed union or nonunion if healing is impaired.
• Malunion, where the bone heals in an abnormal position.
• Nerve or vascular damage in rare cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid activities that increase fall risk, especially in older adults.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or new symptoms like numbness or discoloration develop. These may indicate complications requiring prompt intervention.

Tips for Medical Coders

This code is specific to a subsequent encounter for a closed fracture with routine healing. Documentation must confirm the fracture is nondisplaced, transverse, and located in the shaft of the left fibula. Ensure the encounter is classified as "subsequent" and that healing is documented as routine, with no signs of delayed or abnormal healing.
