S82.422F Displaced transverse fracture of shaft of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced transverse fracture of shaft of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.422F

Summary

A displaced 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 bone fragments are separated and misaligned. The fracture line runs horizontally across the middle portion of the bone. This code applies to a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) with routine healing, indicating the fracture is in the healing phase after initial treatment.

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 (types IIIA, IIIB, or IIIC) involve skin or soft tissue damage, often from severe trauma.

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.
• High-energy trauma, such as motor vehicle collisions.

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 residual open wound or scarring from the initial fracture (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, determine its extent, and evaluate the degree of healing. Clinical documentation should specify the fracture type (IIIA, IIIB, or IIIC) and the routine healing status.

Treatment Options

Treatment may include immobilization with a cast or brace to support healing, pain management, and physical therapy to restore function. For open fractures, wound care and monitoring for infection are essential. Surgical intervention may be required if healing is delayed or complications arise.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, though recovery time varies based on fracture severity and patient health. Follow-up appointments are necessary to monitor healing progress, assess mobility, and adjust treatment as needed. Physical therapy may be recommended to regain strength and range of motion.

Complications

Potential complications include infection (especially with open fractures), delayed union or nonunion, malunion, chronic pain, or nerve damage. Open fractures carry a higher risk of soft tissue injury or infection.

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-fracture care instructions to support healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or new symptoms (e.g., fever, redness, or drainage from the wound) develop. Immediate care is needed for signs of infection or if the leg becomes unstable.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing status to support this code. Ensure the encounter is classified as "subsequent" and that the fracture is open (not closed) with no evidence of delayed or nonunion. Clinical notes should clearly describe the healing phase and any ongoing treatment.
