S82.425F Nondisplaced transverse fracture of shaft of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Nondisplaced transverse fracture of shaft of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.425F

Summary

A nondisplaced 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 fracture line runs horizontally across the middle portion of the bone. The bone fragments remain in their normal anatomical alignment, and the fracture is classified as open (type IIIA, IIIB, or IIIC) with routine healing. This code is used for a subsequent encounter, indicating follow-up care after the initial treatment phase.

Causes

Most commonly caused by direct trauma or high-impact forces to the leg, such as falls, sports injuries, or motor vehicle accidents. Open fractures may result from the same mechanisms, with the bone piercing the skin or the injury causing an external wound. The fracture type (IIIA, IIIB, or IIIC) reflects the extent of soft tissue damage and contamination.

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.

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 (for open fracture types).

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. The classification of the open fracture (IIIA, IIIB, or IIIC) is based on the severity of soft tissue damage and contamination.

Treatment Options

Treatment may include immobilization with a cast or brace to support healing, pain management, and monitoring for infection (especially in open fractures). Surgical intervention may be required for severe open fractures to clean the wound and stabilize the bone. Physical therapy is often recommended to restore function and strength.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, though recovery time may vary depending on the fracture type and individual factors. Follow-up care is essential to monitor healing progress, address any complications, and guide rehabilitation. Routine healing indicates the fracture is progressing without significant issues.

Complications

• Infection (more common in open fractures).
• Delayed healing or nonunion.
• Nerve or blood vessel damage.
• Chronic pain or stiffness.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Use protective gear during high-impact activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving home safety (e.g., removing tripping hazards).
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, or an open wound. Contact a healthcare provider if symptoms worsen, or if there is difficulty bearing weight, numbness, or signs of infection (e.g., redness, pus).

Tips for Medical Coders

This code is specific to a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) with routine healing. Documentation must confirm the fracture type, the subsequent nature of the encounter, and evidence of routine healing (e.g., clinical assessment, imaging, or provider notes). Ensure alignment with the ICD-10-CM guidelines for fracture coding and encounter sequencing.
