S82.464F Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.464F

Summary

A nondisplaced segmental fracture of the shaft of the right fibula is a break in the long, thin bone of the lower leg involving two separate fracture sites along the same bone segment, with the fragments remaining in alignment. This injury is classified as an open fracture type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and potential contamination. The "subsequent encounter" designation applies to follow-up care during the healing phase, where routine healing is documented.

Causes

Most commonly caused by high-energy trauma, such as motor vehicle accidents, falls from significant height, or direct impact to the leg. Twisting injuries or severe rotational forces can also lead to this type of fracture. Open fractures may result from the trauma piercing the skin or from a pre-existing wound becoming contaminated.

Risk Factors

• Participation in high-impact sports or activities with risk of falls.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries that compromise bone integrity.
• Exposure to environments with increased risk of trauma (e.g., construction sites).

Symptoms

• Intense 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.
• Numbness or tingling if nerve involvement occurs.
• Visible wound or open area if the fracture is open.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and wound characteristics. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture type and alignment. The classification of the open fracture (IIIA, IIIB, or IIIC) is determined based on the extent of soft tissue damage and contamination.

Treatment Options

Treatment focuses on stabilizing the fracture and managing the open wound. This may include immobilization with a cast or brace, surgical intervention to clean the wound and stabilize the bone, and antibiotics to prevent infection. Follow-up care involves monitoring healing progress and adjusting treatment as needed.

Prognosis and Follow-Up

With proper treatment, most nondisplaced segmental fractures of the fibula heal well. Routine healing is expected during subsequent encounters, but follow-up appointments are necessary to ensure the fracture remains aligned and the wound heals without complications. Physical therapy may be recommended to restore strength and mobility.

Complications

• Infection, particularly with open fractures.
• Delayed healing or nonunion.
• Nerve or blood vessel damage.
• Chronic pain or instability.
• Limited mobility or functional impairment.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid activities that increase the risk of falls or trauma.
• Seek prompt medical attention for leg injuries to prevent complications.

When to Seek Professional Help

• Severe pain or swelling that worsens over time.
• Signs of infection, such as fever, redness, or pus.
• Numbness, tingling, or loss of circulation in the leg.
• Difficulty bearing weight or moving the leg.
• Wound reopening or drainage.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing during the subsequent encounter. Ensure the code S82.464F is used only when the fracture is nondisplaced, segmental, and involves the right fibula, with the specified open fracture classification and healing status.
