S82.223N Displaced transverse fracture of shaft of unspecified tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Displaced transverse fracture of shaft of unspecified tibia, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Summary

A displaced transverse fracture of the tibial shaft is a break that runs horizontally across the main portion of the tibia (shinbone), with the bone fragments separated and misaligned. This fracture is classified as an open fracture type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination. The term "nonunion" signifies that the fracture has failed to heal properly after an expected period. The injury typically results from direct trauma or high-impact forces and may vary in severity depending on the degree of displacement, soft tissue involvement, and healing status.

Causes

Displaced transverse fractures of the tibial shaft commonly occur due to direct trauma, such as falls, motor vehicle accidents, or sports injuries. High-energy impacts, like those from contact sports or industrial accidents, can also cause these injuries. Less commonly, repetitive stress or overuse may lead to stress fractures that progress to displaced transverse breaks. Open fractures with nonunion often result from inadequate initial treatment, infection, or poor blood supply to the fracture site.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Previous lower leg injuries.
• Age-related bone density loss, particularly in older adults.
• Lack of protective gear during physical activities.
• Poor nutrition or smoking, which can impair bone healing.
• Inadequate initial fracture management or follow-up care.

Symptoms

• Persistent pain at the fracture site, often worsening with activity.
• Swelling, bruising, or tenderness along the shin that does not resolve.
• Difficulty bearing weight or walking, even with support.
• Visible deformity or abnormal movement of the leg.
• Signs of infection, such as redness, warmth, or drainage from the wound site.
• Delayed or absent healing, as indicated by persistent pain or lack of bone union on imaging.

Diagnosis

Diagnosis involves a thorough clinical evaluation, including a detailed history of the injury and symptoms. Physical examination assesses for deformity, swelling, and signs of infection. Imaging studies, such as X-rays, CT scans, or MRI, are used to confirm the fracture type, assess displacement, and evaluate for nonunion or associated soft tissue damage. Laboratory tests may be ordered to check for infection or nutritional deficiencies affecting healing.

Treatment Options

Treatment focuses on promoting fracture union and addressing soft tissue damage. Options may include surgical intervention, such as internal or external fixation, to stabilize the fracture and facilitate healing. Antibiotics are often required for open fractures to prevent or treat infection. Bone grafting or other advanced techniques may be necessary for nonunion. Physical therapy is typically recommended to restore function and strength once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of infection, and the success of treatment. Nonunion fractures may require additional interventions, and recovery can be prolonged. Regular follow-up with imaging and clinical assessments is essential to monitor healing and adjust treatment as needed. Long-term outcomes may include residual pain, stiffness, or functional limitations, particularly if soft tissue damage was extensive.

Complications

• Infection, especially in open fractures.
• Delayed or failed healing (nonunion or malunion).
• Chronic pain or arthritis in the affected joint.
• Nerve or blood vessel damage.
• Muscle weakness or atrophy due to prolonged immobilization.
• Need for additional surgeries or prolonged rehabilitation.

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.
• Quit smoking, as it impairs bone healing.
• Use protective gear during sports or activities with fall risks.
• Follow post-treatment instructions carefully to optimize healing.
• Engage in gradual, supervised physical therapy to restore mobility.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe or worsening pain.
• Signs of infection, such as fever, redness, or drainage.
• New or worsening deformity.
• Inability to bear weight or walk.
• Persistent swelling or bruising that does not improve.

Tips for Medical Coders

This code (S82.223N) is used for a subsequent encounter for an open fracture type IIIA, IIIB, or IIIC of the tibial shaft with nonunion. Documentation must specify the fracture type (IIIA, IIIB, or IIIC) and confirm nonunion. Ensure the encounter is classified as "subsequent" and that the fracture is open with significant soft tissue damage. Verify that the tibia is unspecified (not left or right) and that the fracture is transverse and displaced. Accurate documentation of healing status and fracture characteristics is critical for correct coding.
