S82.262K Displaced segmental fracture of shaft of left tibia, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced segmental fracture of shaft of left tibia, subsequent encounter for closed fracture with nonunion

Summary

A displaced segmental fracture of the shaft of the left tibia with nonunion is a break involving multiple segments of the tibia, where the bone fragments remain misaligned and fail to heal properly. This condition occurs during a subsequent encounter for a closed fracture that has not united after an expected healing period.

Causes

Commonly caused by high-energy trauma such as motor vehicle accidents, falls from significant height, or direct impact injuries. Nonunion may result from inadequate initial stabilization, poor blood supply to the fracture site, infection, or excessive movement during healing.

Risk Factors

• Participation in high-impact sports or activities
• Osteoporosis or bone-weakening conditions
• Smoking, which impairs bone healing
• Poor nutrition or vitamin deficiencies
• Previous lower leg injuries or surgeries

Symptoms

• Persistent pain and swelling in the lower leg
• Visible deformity or irregularity of the shin
• Inability to bear weight on the affected leg
• Bruising and tenderness at the fracture site
• Possible clicking or grinding sensation with movement

Diagnosis

Diagnosis involves a physical examination to assess swelling, deformity, and tenderness. Imaging tests such as X-rays are used to visualize the fracture and nonunion. CT scans may be employed to evaluate bone alignment and fragment details, while MRI can assess soft tissue involvement.

Treatment Options

• Surgical intervention: Internal or external fixation to stabilize the fracture and promote healing.
• Bone grafting: Transplanting bone tissue to stimulate union.
• Electrical stimulation: Using devices to enhance bone growth.
• Physical therapy: To restore function and strength after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and treatment effectiveness. Regular follow-up with imaging is necessary to monitor healing progress. Full recovery may take several months, with potential for long-term mobility limitations if healing is incomplete.

Complications

• Chronic pain or discomfort
• Persistent deformity or instability
• Increased risk of future fractures
• Infection (if surgical intervention is required)
• Limited range of motion in the affected leg

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 physical activities.
• Follow post-treatment instructions carefully to optimize healing.

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 symptoms worsen or do not improve with treatment, or if you notice signs of infection such as redness, warmth, or drainage.

Tips for Medical Coders

Document the subsequent encounter for a closed fracture with nonunion, specifying the left tibia and segmental nature of the fracture. Include details on treatment approaches and any complications to support accurate coding. Ensure documentation reflects the nonunion status and closed fracture type.
