S82.461F Displaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.461F

Summary

A displaced segmental fracture of the shaft of the right 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 IIIA, IIIB, or IIIC), meaning the skin is pierced or there is a wound communicating with the fracture site. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "routine healing" signifies that the fracture is progressing normally without complications.

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. Open fractures may result from the same mechanisms, with additional skin penetration from the injury force or bone fragments.

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.
• Activities with a high risk of falls or direct trauma to the leg.

Symptoms

• 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.
• Visible wound or open area at the fracture site (for open fractures).

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. For open fractures, evaluation of the wound and surrounding tissue is also performed to assess the severity of the injury.

Treatment Options

Treatment depends on the severity of the fracture and the type of open wound. Options may include:

• Surgical intervention to realign and stabilize the bone, such as internal fixation with plates or screws.
• Wound care for the open fracture site, including cleaning and possible debridement.
• Antibiotics to prevent infection.
• Immobilization with a cast or brace to support healing.
• Pain management and physical therapy to restore function.

Prognosis and Follow-Up

With proper treatment, most displaced segmental fractures of the fibula heal well, especially when classified as routine healing. Follow-up care is essential to monitor progress and ensure the fracture is healing correctly. Physical therapy may be recommended to restore strength and mobility. The prognosis is generally good, but recovery time can vary depending on the severity of the injury and the patient's overall health.

Complications

• Infection at the open fracture site.
• Delayed healing or nonunion of the fracture.
• Nerve or blood vessel damage.
• Chronic pain or instability in the leg.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Avoid high-impact activities that increase the risk of falls or trauma.
• Wear appropriate protective gear during sports or activities.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Engage in regular weight-bearing exercises to strengthen bones.
• Use caution on uneven surfaces or in environments with a high risk of falls.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe pain, swelling, or deformity in the leg.
• An open wound or bleeding at the fracture site.
• Inability to bear weight on the affected leg.
• Signs of infection, such as fever, redness, or pus.
• Numbness, tingling, or loss of circulation in the foot or toes.

Tips for Medical Coders

When coding for S82.461F, ensure the documentation specifies:

• The fracture is displaced and segmental.
• The location is the shaft of the right fibula.
• The encounter is subsequent (not initial or acute).
• The fracture is open and classified as type IIIA, IIIB, or IIIC.
• The healing is routine (no complications or delayed healing). Accurate documentation of the fracture type, location, and healing status is critical for correct code assignment.
