S82.424C Nondisplaced transverse fracture of shaft of right fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Nondisplaced transverse fracture of shaft of right fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC
• ICD-10 Code: S82.424C

Summary

A nondisplaced transverse fracture of the shaft of the right 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, meaning there is no significant separation or mispositioning of the fragments. This code specifically applies to initial encounters for open fractures classified as type IIIA, IIIB, or IIIC, indicating a severe open injury with extensive soft tissue damage, contamination, or vascular compromise.

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. Open fractures occur when the overlying skin is broken, exposing the bone to the external environment.

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 collisions or falls from 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 fracture site.
• Possible deformity or instability of the leg structure.
• Signs of infection or contamination at the open wound site.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, deformity, and the extent of the open wound. Imaging tests, such as X-rays, are typically used to confirm the fracture, determine its extent, and evaluate alignment. Additional assessments may include evaluating soft tissue damage, vascular status, and potential contamination at the open wound site.

Treatment Options

Treatment focuses on stabilizing the fracture, managing the open wound, and preventing infection. This may include surgical intervention to clean the wound, realign the bone, and stabilize the fracture with hardware. Antibiotics are often administered to reduce infection risk. Immobilization with a cast or brace may be used post-surgery to support healing. Physical therapy is typically recommended during recovery to restore strength and mobility.

Prognosis and Follow-Up

Prognosis depends on the severity of the open fracture, the extent of soft tissue damage, and the success of treatment. Nondisplaced fractures generally heal well with proper care, but open fractures carry a higher risk of complications. Follow-up appointments are necessary to monitor healing, assess for infection, and adjust treatment as needed. Recovery may take several months, with gradual return to weight-bearing activities guided by the healthcare provider.

Complications

• Infection at the open wound site.
• Delayed healing or nonunion of the fracture.
• Nerve or vascular damage.
• Chronic pain or instability.
• Post-traumatic arthritis.
• Compartment syndrome (increased pressure in the leg muscles).

Lifestyle & Prevention

• Use protective gear during high-impact activities or sports.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid high-risk situations that may lead to falls or trauma.
• Follow post-injury care instructions carefully to support healing.
• Engage in gradual, supervised physical therapy to restore function.

When to Seek Professional Help

Seek immediate medical attention if you experience severe leg pain, swelling, or an open wound after an injury. Signs of infection, such as increased redness, pus, or fever, also require prompt evaluation. Difficulty bearing weight or visible deformity should be assessed by a healthcare professional to rule out fractures or other serious injuries.

Tips for Medical Coders

This code (S82.424C) is specific to the initial encounter for an open fracture of the right fibula, classified as type IIIA, IIIB, or IIIC. Documentation must clearly indicate the fracture type, laterality (right), and that it is an initial encounter. Coders should verify the open fracture classification (IIIA, IIIB, or IIIC) and ensure the encounter is documented as initial. Avoid using this code for subsequent encounters or closed fractures.
