S82.463J Displaced segmental fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

Name of the Condition

• Displaced segmental fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
• ICD-10 Code: S82.463J

Summary

A displaced segmental fracture of the shaft of the unspecified fibula is a break in the long, thin bone of the lower leg, where the bone is fractured into two or more separate pieces with the fragments out of alignment. This injury involves the middle portion of the fibula and is classified as an open fracture (type IIIA, IIIB, or IIIC), meaning the skin is breached and the wound is severe. The term "unspecified" indicates the side (left or right) is not documented. "Subsequent encounter" denotes follow-up care after the initial treatment, and "delayed healing" indicates the fracture has not progressed as expected during the normal healing timeline.

Causes

Most commonly caused by high-energy trauma, such as motor vehicle accidents, falls from significant height, or direct impact to the leg. Open fractures may result from the same mechanisms, with the bone piercing the skin or the trauma causing an external wound. Delayed healing can occur due to infection, poor blood supply, 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.
• Open fracture type (IIIA, IIIB, or IIIC), which increases infection risk and healing challenges.

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.
• Open wound or exposed bone (for open fracture types).
• Signs of infection, such as redness, warmth, or drainage.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, deformity, and wound characteristics. Imaging tests, such as X-rays, are typically used to confirm the fracture, evaluate alignment, and assess healing progress. Additional tests, like CT scans or MRIs, may be ordered to evaluate soft tissue damage or infection. Laboratory tests (e.g., blood work) may be performed to check for infection or nutritional deficiencies affecting healing.

Treatment Options

Treatment focuses on promoting healing and managing the open fracture. This may include surgical intervention to clean the wound, stabilize the fracture (e.g., with plates, screws, or external fixation), and address any infection. Antibiotics are often prescribed for open fractures to prevent or treat infection. Immobilization with a cast or brace may be used to support the leg during healing. Physical therapy is typically recommended to restore strength and mobility once the fracture shows signs of progress.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of infection, and the patient’s overall health. Delayed healing may require extended treatment, including additional surgeries or advanced therapies (e.g., bone grafts). Regular follow-up appointments are necessary to monitor healing progress through imaging and physical exams. Full recovery can take several months, and some patients may experience long-term stiffness or weakness.

Complications

• Infection (especially with open fractures).
• Nonunion or malunion of the fracture.
• Nerve or blood vessel damage.
• Chronic pain or arthritis.
• Limited mobility or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed weight-bearing restrictions to support healing.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Practice good wound care if the fracture is open to prevent infection.
• Use protective gear during sports or activities to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Increased pain, swelling, or redness around the fracture site.
• Signs of infection (e.g., fever, pus, or foul odor from the wound).
• Numbness, tingling, or changes in skin color below the fracture.
• Difficulty moving the leg or bearing weight.
• Worsening deformity or instability.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and the presence of delayed healing to support the S82.463J code. Include details about the wound (e.g., size, contamination) and any surgical interventions performed. Note the "subsequent encounter" status, indicating follow-up care after the initial treatment phase. Ensure the fibula is documented as "unspecified" if the side is not clearly identified.
