S82.462K Displaced segmental fracture of shaft of left fibula, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced segmental fracture of shaft of left fibula, subsequent encounter for closed fracture with nonunion
• ICD-10 Code: S82.462K

Summary

A displaced segmental fracture of the shaft of the left fibula is a break in the long, thin bone on the lateral side of the lower leg, where the bone is broken into two or more separate pieces and the fragments are out of alignment. This is a closed fracture, meaning the skin remains intact. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "nonunion" refers to a failure of the bone to heal properly after an expected period.

Causes

Most commonly caused by direct trauma or high-impact events, such as falls, sports injuries, or motor vehicle accidents. Twisting motions or forceful impacts to the leg can also lead to this type of fracture. Nonunion may result from inadequate immobilization, poor blood supply to the bone, infection, or excessive movement at the fracture site during healing.

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.
• Smoking or poor nutrition, which can impair bone healing.

Symptoms

• Persistent pain and swelling in the lower leg, often lasting beyond the typical healing period.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.
• No visible signs of healing on imaging after several months.

Diagnosis

Diagnosis involves a 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 evaluate for nonunion. Additional tests, like bone scans or MRI, may be performed to assess blood flow and bone healing potential.

Treatment Options

Treatment for nonunion may include surgical intervention, such as bone grafting, internal fixation with plates or screws, or external fixation devices to stabilize the fracture. Non-surgical options, like electrical stimulation or ultrasound therapy, may be considered in some cases. Physical therapy is often recommended to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Follow-up care is essential to monitor healing and adjust treatment as needed. Regular imaging and clinical evaluations help track progress and address complications promptly.

Complications

• Chronic pain or discomfort.
• Limited mobility or functional impairment.
• Increased risk of future fractures.
• Infection, particularly if surgery is required.
• Nerve or vascular damage in severe cases.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs bone healing.
• Use protective gear during sports or activities with fall risks.
• Follow post-treatment instructions carefully to promote healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact your healthcare provider if pain persists, worsens, or if you notice no improvement in symptoms after initial treatment. Signs of infection, such as fever or increased redness, also require prompt evaluation.

Tips for Medical Coders

When coding S82.462K, ensure documentation supports the diagnosis of a displaced segmental fracture of the left fibula shaft, a subsequent encounter, and closed fracture with nonunion. Verify that the encounter is for follow-up care and that nonunion is explicitly documented. Include details about the fracture's alignment, healing status, and any interventions performed.
