S82.464D Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for closed fracture with routine healing
• ICD-10 Code: S82.464D

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 segment, with the bone fragments remaining in their normal alignment. This injury is classified as closed (skin intact) and is now in the healing phase, as indicated by the "subsequent encounter" and "routine healing" designations. The fracture typically affects the middle portion of the fibula and results from significant force or trauma.

Causes

Most commonly caused by high-energy trauma, such as motor vehicle accidents, falls from height, or direct impact to the leg. Twisting injuries or severe rotational forces can also lead to this type of fracture.

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.

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.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging studies, such as X-rays or CT scans, are typically used to confirm the fracture type and alignment. The "subsequent encounter" and "routine healing" designations indicate the fracture is progressing as expected without complications.

Treatment Options

Treatment may include immobilization with a cast or brace to support healing, pain management, and physical therapy to restore strength and mobility. Surgical intervention is rarely needed for nondisplaced fractures but may be considered if alignment issues arise.

Prognosis and Follow-Up

With proper care, most nondisplaced segmental fractures heal within 6–8 weeks. Follow-up appointments monitor healing progress, and imaging may be repeated to confirm bone union. Return to normal activities is gradual, guided by pain levels and functional recovery.

Complications

Rare complications include nonunion (failure to heal), malunion (poor alignment), or nerve damage. Infection risk is low for closed fractures but may increase with surgical intervention.

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.
• Practice safe movement techniques to reduce injury risk.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., numbness, discoloration) develop. Prompt evaluation is needed if the cast or brace becomes loose or uncomfortable.

Tips for Medical Coders

Document the fracture type (nondisplaced segmental), laterality (right), encounter stage (subsequent), and healing status (routine) to support accurate coding. Include details on imaging results, treatment plans, and follow-up notes to confirm the fracture is healing without complications.
