S82.462H Displaced segmental fracture of shaft of left fibula, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Displaced segmental fracture of shaft of left fibula, subsequent encounter for open fracture type I or II with delayed healing
• ICD-10 Code: S82.462H

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 injury involves the middle portion of the fibula and is classified as an open fracture (type I or II), meaning the skin is broken but the wound is relatively small and clean. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "delayed healing" refers to a slower-than-expected recovery process.

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. Open fractures may result from trauma that penetrates the skin, while delayed healing can stem from factors like poor blood supply, infection, or inadequate immobilization.

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.
• Poor nutrition or underlying medical conditions affecting healing.

Symptoms

• Persistent 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.
• Delayed healing may present as prolonged pain or lack of progress in fracture union.

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 and determine its extent and alignment. Additional tests, like CT scans or MRIs, may be ordered to evaluate healing progress or detect complications. Clinical evaluation of the wound (for open fractures) and assessment of healing status are also critical.

Treatment Options

Treatment focuses on promoting healing and managing symptoms. This may include immobilization with a cast or brace, pain management, and monitoring for infection. Surgical intervention, such as internal fixation, may be considered if the fracture is unstable or healing is severely delayed. Physical therapy is often recommended to restore function once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and adherence to treatment. Delayed healing may extend recovery time, but most fractures eventually heal with appropriate care. Follow-up visits are essential to monitor progress, adjust treatment, and address any complications. Regular imaging may be used to assess bone union.

Complications

• Infection, particularly with open fractures.
• Nonunion or malunion of the fracture.
• Nerve or blood vessel damage.
• Chronic pain or stiffness.
• Delayed healing, as indicated by the code.

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.
• Use protective gear during sports or activities with fall risks.
• Follow post-injury care instructions closely 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 signs of infection (e.g., redness, pus, fever) at the fracture site.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (left fibula), and encounter type (subsequent) clearly. Note the presence of delayed healing, as this impacts coding and reflects the clinical status. Ensure documentation supports the open fracture classification and healing timeline to justify the code.
