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

Name of the Condition

• Displaced fracture of left tibial tuberosity, subsequent encounter for closed fracture with routine 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. This code specifies a subsequent encounter for a closed fracture with routine healing, indicating the fracture is not penetrating the skin and is progressing normally without complications. Displacement means the bone fragments are misaligned, which may affect knee function and stability.

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. The subsequent encounter phase implies the initial injury has already been treated, and the focus is on monitoring healing.

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

Symptoms

• Mild to moderate pain and swelling over the tibial tuberosity
• Gradual improvement in knee extension and weight-bearing ability
• Reduced deformity or abnormal positioning as healing progresses
• Minimal bruising or discoloration in the affected area

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and functional limitations. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. Follow-up imaging may be ordered to monitor healing progress. Clinical notes should document the fracture's status and absence of complications.

Treatment Options

• Continued immobilization or bracing if needed for stability
• Pain management with analgesics or anti-inflammatory medications
• Physical therapy to restore range of motion and strength
• Monitoring for signs of delayed healing or complications

Prognosis and Follow-Up

Most fractures with routine healing progress well, with full recovery expected over several weeks to months. Follow-up appointments are typically scheduled to assess healing and adjust treatment. Complications are rare but may include persistent pain or limited mobility if healing is delayed.

Complications

• Delayed union or nonunion of the fracture
• Persistent pain or functional limitations
• Malunion (improper healing leading to deformity)
• Rarely, infection or nerve damage

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use proper protective gear during sports or physical activities
• Maintain bone health through adequate nutrition and exercise
• Gradually resume activity under medical guidance to prevent re-injury

When to Seek Professional Help

Seek medical attention if symptoms worsen, such as increased pain, swelling, or inability to bear weight. Contact a provider if there are signs of infection (e.g., fever, redness) or if healing does not progress as expected.

Tips for Medical Coders

Document the fracture's status as "subsequent encounter" and confirm it is closed with routine healing. Include details on imaging results, clinical assessments, and any treatment modifications. Ensure the encounter aligns with the healing phase and no complications are present.
