S82.421D Displaced transverse fracture of shaft of right fibula, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Displaced transverse fracture of shaft of right fibula, subsequent encounter for closed fracture with routine healing
• ICD-10 Code: S82.421D

Summary

A displaced 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 bone fragments are separated and misaligned. This is a closed fracture, meaning the skin remains intact, and it represents a subsequent encounter for treatment during the healing phase. The transverse pattern indicates the fracture line runs horizontally across the bone, and routine healing confirms the fracture is progressing without complications.

Causes

Most commonly caused by direct trauma or high-impact forces to the leg, such as falls, sports injuries, or motor vehicle accidents. Twisting motions or sudden impacts can also lead to this type of fracture.

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.

Symptoms

• 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.

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, determine its extent, and evaluate alignment. For subsequent encounters, imaging may also assess healing progress.

Treatment Options

Treatment focuses on supporting healing and may include immobilization with a cast or brace, pain management, and physical therapy to restore strength and mobility. Routine healing indicates no additional interventions are typically required beyond monitoring.

Prognosis and Follow-Up

With proper care, most fractures heal within 6–8 weeks. Follow-up appointments monitor healing progress, and physical therapy may be recommended to regain full function. Routine healing suggests a favorable outcome with minimal long-term effects.

Complications

While routine healing reduces risks, potential complications include delayed union, nonunion, or persistent pain. Infection is rare in closed fractures but may occur if the skin is compromised.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through adequate calcium and vitamin D intake.
• Perform exercises to strengthen leg muscles and improve balance.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms like numbness or discoloration develop. These may indicate complications requiring prompt evaluation.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with routine healing. Ensure clinical notes specify the fracture’s status (e.g., healing progress, absence of complications) to support the code. Include details on immobilization, therapy, or follow-up imaging if performed.
