S82.423F Displaced transverse fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced transverse fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.423F

Summary

A displaced transverse fracture of the shaft of the unspecified 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, and the displacement indicates the fragments are not in their normal anatomical position. This code represents a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, with routine healing, meaning the fracture is in a healing phase following an initial injury where the skin was breached and the wound is healing without significant complications.

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. Open fractures occur when the bone pierces the skin or when external force damages the skin over the fracture site, and the subsequent encounter indicates ongoing management of the healing process.

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.
• Conditions that impair wound healing or increase infection risk.

Symptoms

• Pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Visible deformity or instability of the leg structure.
• Possible signs of ongoing healing, such as reduced swelling or improved mobility.

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 type and alignment. For open fractures, evaluation of the wound and surrounding tissue is also performed to determine the extent of skin and soft tissue damage. Follow-up imaging may be used to monitor healing progress during subsequent encounters.

Treatment Options

Treatment focuses on promoting healing and restoring function. This may include immobilization with a cast or brace, pain management, and monitoring for infection. Surgical intervention may be required if the fracture is unstable or if there are complications with the open wound. Physical therapy is often recommended to restore strength and mobility once healing is underway.

Prognosis and Follow-Up

Prognosis is generally favorable with proper treatment and adherence to follow-up care. Routine healing indicates the fracture is progressing without major complications, but regular monitoring is necessary to ensure the bone and soft tissue heal appropriately. Follow-up appointments may involve repeat imaging and physical assessments to track recovery.

Complications

• Infection at the fracture site or wound.
• Delayed healing or nonunion of the bone.
• Nerve or vascular damage.
• Chronic pain or instability.
• Limited mobility or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through a balanced diet and regular exercise.
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if there is increased pain, swelling, redness, or drainage from the wound, or if there are signs of infection. Contact a healthcare provider if mobility does not improve or if new symptoms develop during the healing process.

Tips for Medical Coders

This code is used for a subsequent encounter for an open fracture of the fibula shaft, classified as type IIIA, IIIB, or IIIC, with routine healing. Documentation should specify the fracture type, the encounter stage (subsequent), and confirmation of routine healing. Ensure the open fracture classification and healing status are clearly documented to support accurate coding.
