S82.466F Nondisplaced segmental fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Nondisplaced segmental fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.466F

Summary

A nondisplaced segmental fracture of the shaft of the unspecified fibula is a break in the long, thin bone of the lower leg involving two separate fracture sites along the same bone segment, with the bone fragments remaining in their normal alignment. This type of fracture is classified as an open fracture type IIIA, IIIB, or IIIC, meaning the overlying skin is breached with significant soft tissue damage. The "subsequent encounter" designation indicates this is a follow-up visit for the fracture, and "routine healing" confirms the fracture is progressing without complications.

Causes

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

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 typically involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies such as X-rays or CT scans to confirm the fracture type and alignment. The open fracture classification (IIIA, IIIB, or IIIC) is determined by the extent of soft tissue damage and contamination. Routine healing is confirmed through follow-up imaging and clinical assessment.

Treatment Options

Treatment focuses on managing the open fracture to prevent infection and promoting healing. This may include wound care, antibiotics, and immobilization with a cast or brace. Surgical intervention may be required for severe soft tissue damage or to stabilize the fracture. Physical therapy is often recommended to restore function once healing is underway.

Prognosis and Follow-Up

With proper treatment, most nondisplaced segmental fractures of the fibula heal well, especially when classified as routine healing. Follow-up care is essential to monitor for complications such as infection or delayed union. Full recovery may take several months, depending on the severity of the injury and the patient’s overall health.

Complications

• Infection at the fracture site, particularly with open fractures.
• Delayed or nonunion of the fracture.
• Nerve or vascular damage due to the initial trauma.
• Chronic pain or instability in the affected leg.

Lifestyle & Prevention

• Avoid high-impact activities that increase fracture risk.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Use protective gear during sports or activities with fall risks.
• Address underlying conditions like osteoporosis to reduce bone fragility.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a leg injury. Follow up with a healthcare provider if symptoms worsen or if you notice signs of infection, such as redness, warmth, or drainage from the wound.

Tips for Medical Coders

This code (S82.466F) is used for a subsequent encounter of a nondisplaced segmental fracture of the fibula shaft with an open fracture type IIIA, IIIB, or IIIC, where healing is routine. Documentation should clearly indicate the fracture type, encounter stage, and healing status. Ensure the open fracture classification (IIIA, IIIB, or IIIC) is supported by clinical notes, and confirm that the encounter is subsequent (not initial) and healing is routine.
