S82.463C Displaced segmental fracture of shaft of unspecified fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Displaced segmental fracture of shaft of unspecified fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC
• ICD-10 Code: S82.463C

Summary

A displaced segmental fracture of the shaft of the unspecified fibula is a break in the long, thin bone of the lower leg, where the bone is fractured into two or more separate pieces with the fragments out of alignment. This injury involves the middle portion of the fibula and is classified as an open fracture (type IIIA, IIIB, or IIIC), meaning the skin is broken, exposing the fracture site. The "initial encounter" designation indicates this is the first time the patient is receiving treatment for this specific injury.

Causes

Most commonly caused by direct trauma or high-impact events, such as falls, sports injuries, or motor vehicle accidents. Twisting motions or forceful impacts to the leg can also lead to this type of fracture. Open fractures occur when the force is severe enough to break the skin and underlying soft tissues.

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.
• High-energy trauma, such as motor vehicle accidents or falls from significant height.

Symptoms

• Severe pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Visible wound or open skin at the fracture site.
• Possible deformity or instability of the leg structure.
• Numbness or tingling if nerve involvement occurs.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, deformity, and the presence of an open wound. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine its extent and alignment. Additional imaging, like CT scans, may be used to evaluate soft tissue damage. The open nature of the fracture is determined by clinical assessment of the wound and surrounding tissues.

Treatment Options

• Immediate wound care and irrigation to reduce infection risk.
• Surgical intervention to clean the wound, stabilize the fracture (e.g., with plates, screws, or rods), and repair soft tissues.
• Antibiotics to prevent or treat infection.
• Pain management and immobilization (e.g., casting or splinting) during recovery.
• Physical therapy to restore mobility and strength after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and treatment response. Open fractures carry a higher risk of infection and complications, which may prolong recovery. Follow-up care includes monitoring for infection, assessing fracture healing, and guiding rehabilitation. Regular imaging and clinical evaluations are typically required to ensure proper recovery.

Complications

• Infection at the fracture site or wound.
• Delayed healing or nonunion of the fracture.
• Nerve or blood vessel damage.
• Chronic pain or instability.
• Post-traumatic arthritis in the ankle or knee.
• Compartment syndrome (increased pressure in the leg tissues).

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, construction).
• 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.
• Follow safety protocols in high-impact environments (e.g., wearing seatbelts, using proper footwear).

When to Seek Professional Help

Seek immediate medical attention if you experience severe leg pain, swelling, deformity, or an open wound after an injury. Signs of infection (e.g., fever, increasing pain, redness, or pus) or numbness/tingling in the leg also require prompt evaluation.

Tips for Medical Coders

This code (S82.463C) is used for a displaced segmental fracture of the fibula shaft with an open fracture type IIIA, IIIB, or IIIC, documented as the initial encounter. Coders must confirm the fracture is segmental (two separate fracture sites), displaced, and open (type III). Documentation should specify the fracture type (IIIA, IIIB, or IIIC) and that this is the initial treatment episode. Ensure alignment with clinical notes and avoid using this code for closed fractures or subsequent encounters.
