S82.464B Nondisplaced segmental fracture of shaft of right fibula, initial encounter for open fracture type I or II

Name of the Condition

• Nondisplaced segmental fracture of shaft of right fibula, initial encounter for open fracture type I or II
• ICD-10 Code: S82.464B

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 I or II, meaning the overlying skin is compromised but the wound is typically small and clean. The fracture affects the middle portion of the fibula and is documented during the initial encounter for treatment.

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 break in the skin (for open fractures).

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

Treatment Options

• Wound cleaning and debridement for open fractures to reduce infection risk.
• Immobilization with a cast, brace, or splint to stabilize the fracture.
• Pain management with medications or other interventions.
• Surgical intervention may be required if the fracture is unstable or if soft tissue damage is severe.
• Physical therapy to restore mobility and strength after healing.

Prognosis and Follow-Up

Prognosis is generally favorable with proper treatment, especially for nondisplaced fractures. Follow-up care includes monitoring for healing progress, assessing for complications, and adjusting treatment as needed. Regular imaging may be used to ensure proper alignment and bone union. Return to normal activities depends on the severity of the injury and adherence to treatment plans.

Complications

• Infection, particularly with open fractures.
• Delayed healing or nonunion of the fracture.
• Nerve or blood vessel damage.
• Chronic pain or instability.
• Post-traumatic arthritis in the ankle or knee.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., helmets, padding).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid activities that increase fall risk, especially in older adults.
• Strengthen leg muscles to improve stability and reduce injury likelihood.
• Follow safety protocols in environments with trauma risks.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible bone or wound, or signs of infection (e.g., fever, increased redness). Prompt evaluation is critical for open fractures to prevent complications.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right fibula. For open fractures, classify the type (I or II) based on wound characteristics. Ensure the encounter is documented as initial to align with the code. Include details about the fracture pattern (segmental) and any associated injuries to support accurate coding.
