S82.425B Nondisplaced transverse fracture of shaft of left fibula, initial encounter for open fracture type I or II

Name of the Condition

• Nondisplaced transverse fracture of shaft of left fibula, initial encounter for open fracture type I or II
• ICD-10 Code: S82.425B

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 bone and the bone fragments remain in their normal anatomical position. This injury is classified as an open fracture type I or II, indicating a break in the skin with minimal contamination or a larger wound without significant soft tissue damage. The term "initial encounter" denotes the first episode of care for this specific fracture.

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. Open fractures may result from the same mechanisms, with the bone piercing the skin or the injury causing an external wound.

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 open wound or break in the skin (for open fracture types).
• Minimal deformity due to nondisplacement.

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 alignment. For open fractures, the wound is examined to classify the type (I or II) based on size and contamination.

Treatment Options

• Wound care for open fractures to prevent infection.
• Immobilization with a cast or brace to stabilize the bone.
• Pain management with medications.
• Surgical intervention may be required for severe open fractures or if soft tissue damage is present.
• Physical therapy to restore strength and mobility after healing.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, especially with proper immobilization and care. Follow-up appointments are necessary to monitor healing, assess for complications, and guide rehabilitation. Open fractures require close monitoring for infection and may have a longer recovery period.

Complications

• Infection, particularly with open fractures.
• Delayed healing or nonunion.
• Nerve or blood vessel damage.
• Chronic pain or instability.
• Post-traumatic arthritis in severe cases.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving home safety (e.g., removing tripping hazards).
• Strengthen leg muscles to support the fibula.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to bear weight, visible deformity, or an open wound. Prompt care is critical for open fractures to reduce infection risk and ensure proper healing.

Tips for Medical Coders

Document the fracture type (nondisplaced), location (left fibula), and encounter type (initial) clearly. For open fractures, specify the type (I or II) based on wound size and contamination. Ensure documentation supports the classification to align with coding guidelines.
