S82.152G Displaced fracture of left tibial tuberosity, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Displaced fracture of left tibial tuberosity, subsequent encounter for closed fracture with delayed healing

Summary

A displaced fracture of the left tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches. Displacement means the bone fragments are misaligned, which may affect knee function. This code specifies a subsequent encounter for a closed fracture with delayed healing, indicating the fracture has not progressed as expected during treatment. The injury typically results from trauma or excessive stress on the knee, particularly in active individuals.

Causes

Traumatic injury is the primary cause, such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. Sports-related incidents, motor vehicle accidents, or other high-impact events can lead to this fracture. Delayed healing may occur due to factors like inadequate immobilization, poor blood supply, or underlying health conditions affecting bone repair.

Risk Factors

• Participation in activities with rapid knee extension or jumping (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Osteoporosis or bone-weakening conditions
• Smoking or poor nutrition, which can impair healing

Symptoms

• Persistent pain and swelling over the tibial tuberosity
• Inability to fully extend the knee or bear weight
• Visible deformity or abnormal positioning of the knee
• Bruising or discoloration in the affected area
• Delayed healing signs, such as lack of progress on imaging

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. Additional tests like MRI or CT scans may be ordered to assess healing progress. Clinical evaluation of healing timelines and patient history helps determine if healing is delayed.

Treatment Options

Treatment focuses on promoting healing and restoring function. Options may include continued immobilization, physical therapy to strengthen surrounding muscles, or surgical intervention if displacement persists. Pain management and activity modification are often part of the plan. Follow-up imaging monitors healing progress.

Prognosis and Follow-Up

Prognosis depends on the severity of displacement and adherence to treatment. Most fractures heal with proper care, but delayed healing may extend recovery time. Regular follow-up appointments assess progress, and adjustments to treatment plans are made as needed. Full return to activity is gradual, guided by clinical and imaging findings.

Complications

• Nonunion or malunion of the fracture
• Chronic pain or knee instability
• Reduced range of motion
• Infection (if surgical intervention is required)
• Long-term functional limitations

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 proper protective gear during sports
• Engage in low-impact exercises to maintain strength without stressing the knee
• Follow post-injury rehabilitation protocols closely

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility declines. Contact a provider if there are signs of infection (e.g., fever, redness) or if the knee cannot bear weight. Persistent symptoms after treatment warrant reevaluation to rule out complications.

Tips for Medical Coders

This code is for a subsequent encounter of a closed fracture with delayed healing. Document the encounter type (subsequent) and confirm the fracture remains closed. Note any factors contributing to delayed healing, such as patient compliance or comorbidities, to support coding accuracy. Ensure alignment with clinical documentation and follow-up care details.
