S82.154H Nondisplaced fracture of right tibial tuberosity, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced fracture of right tibial tuberosity, subsequent encounter for open fracture type I or II with delayed healing

Summary

A nondisplaced fracture of the right tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches, with no misalignment of bone fragments. This is a subsequent encounter for an open fracture type I or II, meaning the skin over the fracture site was compromised but the wound is limited, and healing is delayed. The tibial tuberosity is critical for knee extension, and even nondisplaced fractures can impact function.

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. Open fractures occur when the injury breaches the skin, exposing the fracture site. Delayed healing may result from factors like poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Activities involving sudden stops or jumps
• Poor nutrition or underlying health conditions affecting bone healing

Symptoms

• Localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Visible wound or laceration at the fracture site (for open fractures)
• Bruising or tenderness on palpation
• Persistent pain or lack of progress in healing over time

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. CT or MRI may be used to assess soft tissue damage or healing status. Clinical evaluation of the open wound and healing progress is also critical.

Treatment Options

Treatment focuses on stabilizing the fracture, promoting healing, and managing the open wound. Options may include immobilization with a cast or brace, wound care for the open fracture, pain management, and physical therapy to restore function. Surgical intervention may be considered if healing does not progress or if complications arise.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the effectiveness of treatment, and individual healing capacity. Follow-up care is essential to monitor healing progress, adjust treatment as needed, and prevent complications. Physical therapy is often recommended to restore strength and mobility once healing allows.

Complications

• Infection at the fracture site
• Nonunion or malunion of the fracture
• Chronic pain or stiffness
• Impaired knee function
• Nerve or vascular damage

Lifestyle & Prevention

• Use proper protective gear during high-impact activities
• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Avoid sudden, forceful movements that strain the knee
• Gradually increase activity levels to prevent overuse injuries

When to Seek Professional Help

Seek medical attention if there is severe pain, swelling, or inability to bear weight, or if the open wound shows signs of infection (e.g., redness, pus, fever). Persistent pain or lack of healing progress also warrants evaluation.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture type I or II with delayed healing. Include details on the fracture status (nondisplaced), the open wound classification, and evidence of delayed healing (e.g., imaging or clinical notes). Ensure the code aligns with the specific encounter type and healing status.
