S82.145N Nondisplaced bicondylar fracture of left tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Nondisplaced bicondylar fracture of left tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Summary

This condition describes a fracture of the left tibia where both the medial and lateral condyles are broken but remain in their original alignment. It is a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage, and includes nonunion, meaning the fracture has failed to heal properly.

Causes

These fractures typically result from high-energy trauma, such as motor vehicle accidents, falls from height, or severe sports injuries. Open fractures occur when the bone pierces the skin, and nonunion may develop due to inadequate blood supply, infection, or improper immobilization.

Risk Factors

• High-impact activities or occupations with a risk of trauma.
• Osteoporosis or other bone-weakening conditions.
• Poor blood supply to the fracture site.
• Inadequate initial treatment or immobilization.
• Infection at the fracture site.

Symptoms

• Persistent pain at the fracture site, often worsening with activity.
• Swelling, bruising, or drainage from the open wound.
• Inability to bear weight on the affected leg.
• Visible deformity or instability of the knee.
• Limited range of motion or stiffness.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and wound characteristics, followed by imaging studies such as X-rays or CT scans to confirm the fracture type and nonunion. Additional tests may evaluate blood flow or infection.

Treatment Options

• Surgical intervention to stabilize the fracture, often with internal fixation.
• Debridement to clean the wound and address infection.
• Bone grafting or other procedures to promote healing in cases of nonunion.
• Antibiotics for open fractures to prevent or treat infection.
• Immobilization with a cast or brace during recovery.
• Physical therapy to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and response to treatment. Follow-up appointments are essential to monitor healing, assess for complications, and adjust treatment as needed. Recovery may be prolonged due to nonunion or infection.

Complications

• Infection at the fracture site or wound.
• Delayed or failed healing (nonunion).
• Nerve or blood vessel damage.
• Chronic pain or arthritis in the knee.
• Limited mobility or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed weight-bearing restrictions.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Practice proper wound care if the fracture is open.
• Use protective equipment during activities to reduce injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or drainage from the wound, or if you cannot bear weight on the affected leg. Contact your healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC), the presence of nonunion, and the subsequent encounter status. Include details about the open wound, treatment provided, and any complications to ensure accurate coding. Verify that all elements of the code are supported by clinical documentation.
