S82.422G Displaced transverse fracture of shaft of left fibula, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Displaced transverse fracture of shaft of left fibula, subsequent encounter for closed fracture with delayed healing
• ICD-10 Code: S82.422G

Summary

A displaced transverse 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 fragments are separated and misaligned. The fracture line runs horizontally across the middle portion of the bone. This is a subsequent encounter for a closed fracture (skin remains intact) with delayed healing, indicating the fracture is not progressing as expected during the healing process.

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. Delayed healing may result from factors like poor blood supply, infection, or inadequate immobilization.

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 healing.

Symptoms

• Persistent pain and swelling in the lower leg beyond the typical healing timeline.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.
• Lack of visible progress in healing during follow-up imaging.

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, evaluate the degree of displacement, and assess healing progress. Additional tests may be ordered to identify causes of delayed healing, such as blood work or bone scans.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace, pain management, and physical therapy to restore function. In cases of significant delay, surgical intervention (e.g., bone grafting or fixation) may be considered. Nutritional support and smoking cessation are also recommended to optimize healing.

Prognosis and Follow-Up

Prognosis depends on the underlying cause of delayed healing and the effectiveness of treatment. Most fractures eventually heal with appropriate care, but recovery may take longer than usual. Regular follow-up appointments and imaging are necessary to monitor progress. Physical therapy is often required to regain strength and mobility.

Complications

• Nonunion (failure of the fracture to heal).
• Malunion (healing in an incorrect position).
• Chronic pain or stiffness.
• Nerve or vascular damage.
• Infection (if surgical intervention is needed).

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 healing.
• Use protective gear during sports or activities with fall risks.
• Follow post-injury care instructions closely to prevent re-injury.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity, or if you notice signs of infection (e.g., redness, warmth, or pus at the injury site). Contact your healthcare provider if symptoms worsen or do not improve with treatment, or if you have difficulty bearing weight on the affected leg.

Tips for Medical Coders

Document the fracture type (displaced transverse), location (shaft of left fibula), encounter type (subsequent), and healing status (delayed healing) to support accurate coding. Include details on imaging results, treatment plans, and any factors contributing to delayed healing (e.g., poor blood supply, noncompliance) to justify the code selection. Ensure documentation aligns with the specific criteria for "subsequent encounter" and "delayed healing" as defined in the ICD-10-CM guidelines.
