S82.401K Unspecified fracture of shaft of right fibula, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Unspecified fracture of shaft of right fibula, subsequent encounter for closed fracture with nonunion
• ICD-10 Code: S82.401K

Summary

This condition refers to a fracture (break) of the middle portion of the fibula, the smaller bone in the lower leg, on the right side. The term "unspecified" indicates the exact location of the fracture on the fibula has not been detailed. It is a closed fracture, meaning the bone is broken but the skin is not pierced, and it is a subsequent encounter for treatment of a fracture that has failed to heal (nonunion).

Causes

Most commonly caused by direct trauma or impact to the outside of the leg, such as from falls, sports injuries, or accidents. Nonunion may result from inadequate immobilization, poor blood supply to the bone, infection, or severe displacement of the fracture fragments.

Risk Factors

• Participation in contact sports or high-impact activities.
• High-risk occupations or environments increasing fall or injury likelihood.
• Osteoporosis or reduced bone density, which weakens bone strength.
• Advanced age, which may compromise bone integrity.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain and swelling in the lower leg.
• Difficulty bearing weight on the leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.
• Lack of improvement in symptoms over time despite prior treatment.

Diagnosis

Physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays or CT scans, are typically used to confirm the fracture and determine if healing has occurred. Additional tests may evaluate blood flow or bone density.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• Immobilization of the leg using a splint or cast to stabilize the fracture.
• Pain management with medications such as analgesics.
• Physical therapy to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Follow-up care is essential to monitor healing and adjust treatment as needed. Regular imaging may be required to assess progress.

Complications

• Chronic pain or discomfort.
• Persistent instability or deformity of the leg.
• Increased risk of future fractures due to weakened bone.
• Potential need for additional surgeries if healing does not occur.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or high-risk activities.
• Follow post-treatment instructions carefully to optimize healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to bear weight, or if symptoms worsen despite treatment.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure clinical documentation specifies the fracture type (closed), the bone involved (right fibula shaft), and the nonunion status to support accurate coding.
