S82.434K Nondisplaced oblique fracture of shaft of right fibula, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced oblique fracture of shaft of right fibula, subsequent encounter for closed fracture with nonunion

Summary

This condition describes a break in the long, thin shaft of the right fibula, one of the two bones in the lower leg. The fracture is oblique (at an angle) and nondisplaced, meaning the bone fragments remain in their normal alignment. It is classified as a closed fracture, with no open wound or communication to the fracture site, and is documented as a subsequent encounter for a fracture that has failed to heal (nonunion). This type of fracture typically results from trauma and requires ongoing management to address the nonunion.

Causes

Direct trauma to the lower leg, such as from falls, sports injuries, or motor vehicle accidents. Twisting injuries during physical activity can also lead to this type of fracture.

Risk Factors

• Engaging in high-impact sports or activities.
• Osteoporosis or weakened bone density.
• Previous fractures or bone-related conditions.
• Poor blood supply to the fracture site.
• Inadequate immobilization during initial healing.

Symptoms

• Persistent pain localized to the lower right leg, even after initial treatment.
• Swelling and bruising around the fracture site that may not resolve.
• Difficulty bearing weight on the affected leg.
• Possible tenderness to touch at the fracture site.
• No visible deformity, as the fracture remains nondisplaced.

Diagnosis

Physical examination to assess tenderness, swelling, and alignment. Imaging tests, such as X-rays, to confirm the fracture type, location, and lack of displacement. Additional imaging, like CT scans or MRI, may be used to evaluate for nonunion. Evaluation of healing progress compared to expected timelines.

Treatment Options

• Continued immobilization with a cast or splint to support the bone.
• Pain management with medications.
• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• Physical therapy to restore strength and mobility once healing progresses.
• Monitoring for signs of infection or further complications.

Prognosis and Follow-Up

Prognosis depends on the success of treatment for the nonunion. With appropriate intervention, healing may occur, but recovery can be prolonged. Regular follow-up appointments are necessary to assess healing and adjust treatment plans. Long-term monitoring may be required to ensure the fracture site stabilizes.

Complications

• Delayed or failed healing (nonunion) requiring additional intervention.
• Chronic pain or discomfort at the fracture site.
• Limited mobility or functional impairment.
• Increased risk of future fractures in the affected area.
• Possible need for surgical revision if initial treatment is unsuccessful.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed weight-bearing restrictions to support healing.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or activities to reduce injury risk.
• Attend all follow-up appointments to monitor healing progress.

When to Seek Professional Help

• Persistent or worsening pain despite treatment.
• Increased swelling, redness, or drainage from the fracture site.
• Inability to bear weight on the affected leg.
• Signs of infection, such as fever or pus.
• New or worsening deformity at the fracture site.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure the record specifies the fracture type (nondisplaced oblique), location (shaft of right fibula), and the presence of nonunion. Include details on treatment provided and any imaging results that confirm nonunion to support code assignment.
