S82.426H Nondisplaced transverse fracture of shaft of unspecified fibula, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced transverse fracture of shaft of unspecified fibula, subsequent encounter for open fracture type I or II with delayed healing
• ICD-10 Code: S82.426H

Summary

A nondisplaced 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 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 I or II (skin is broken but the wound is small and clean with minimal soft tissue damage). This is a subsequent encounter for treatment, indicating ongoing care for delayed healing.

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 may result from the same mechanisms, with the force sufficient to break the skin and expose the fracture site. Delayed healing may occur due to factors like poor blood supply, infection, or inadequate immobilization.

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.
• Smoking or poor nutrition, which can impair healing.
• Certain medical conditions (e.g., diabetes) that affect circulation.

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.
• Delayed healing signs, such as prolonged pain or lack of progress in recovery.

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. Additional tests (e.g., CT scans or MRIs) may be ordered to evaluate soft tissue damage or healing progress. Documentation should specify the fracture type (open I or II) and the presence of delayed healing.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace, pain management, and physical therapy. For open fractures, wound care is essential to prevent infection. Surgical intervention may be considered if healing is significantly delayed or if there are complications. Follow-up imaging and clinical assessments monitor progress.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, overall health, and adherence to treatment. Most nondisplaced fractures heal with proper care, but delayed healing may extend recovery time. Regular follow-up appointments are necessary to assess progress and adjust treatment plans. Full weight-bearing and return to normal activities are gradual, guided by clinical improvement.

Complications

• Infection at the fracture site, especially with open fractures.
• Nonunion (failure of the bone to heal) or malunion (improper healing).
• Chronic pain or stiffness in the leg.
• Nerve or blood vessel damage.
• Delayed functional recovery.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective gear during sports or activities with fall risks.
• Quit smoking, as it impairs bone healing.
• Follow prescribed weight-bearing restrictions and rehabilitation exercises.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact your healthcare provider if pain worsens, swelling persists, or you notice signs of infection (e.g., redness, warmth, or pus). Follow up as scheduled to monitor healing progress.

Tips for Medical Coders

Document the fracture type (open I or II), the presence of delayed healing, and the subsequent encounter status clearly. Ensure the fibula is specified as "unspecified" (not right or left) and that the fracture is transverse and nondisplaced. Include details about treatment provided and any factors contributing to delayed healing to support accurate coding.
